The structure of the house will not last long if the foundation is not protected from moisture. Concrete is the basis of the foundation, it is strong and durable, but is not able to undergo humid environment. From above, this part of the house is affected by precipitation, while from below - soil and groundwater. This should be added to the heaving and pressure of the soil, the chemical reagents that are contained in the water, as well as the temperature difference in the ground and underground parts of the foundation.

The need for waterproofing

If the foundation is not isolated at the time of construction, then in a couple of years you will have to pay a much larger amount for the restoration of the material.

Waterproofing is presented today in a huge assortment, it can be:

• mastic;
• roll;
• liquid.

The latter variety is more effective, with its help you can create a seamless contour and cut off the path of moisture inside the structure.

Varieties of liquid waterproofing

Liquid waterproofing for concrete is represented by several materials, the most common are liquid rubber and liquid glass. Manufacturers claim only the advantages of these solutions, but in practice it turns out that there are also disadvantages. If we compare liquid rubber and glass with rolled bituminous materials, as well as membrane films, then the former will be distinguished by the ease of application to the base of various shapes. The material is able to penetrate even into hard-to-reach places.

Using liquid glass or rubber, you can create a layer that is more resistant to moisture than bituminous materials.

The technology of waterproofing concrete with liquid glass does not provide for heating the material, which facilitates the application and increases the level of fire safety. The resulting layer is non-toxic, it does not melt in the heat, and also does not ignite. These materials can replace several layers of rolled waterproofing at once, however, the application should be carried out in a rather thin layer, so the final weight is negligible.

Scope of use

With any surfaces, liquid rubber and glass are able to adhere well. These advantages have significantly expanded the scope of the described materials, therefore today they are used to waterproof structures and premises with the constant presence of water.

This should include:

• fonts in the baths;
• fountains;
• base bowls of pools.

Liquid glass reviews

In building hypermarkets, in particular in Leroy, liquid waterproofing of concrete is offered in a wide range. Among other materials, liquid glass should be distinguished, the service life of which is 5 years. This does not mean at all that after this period the foundation will lose its protection. Glass during operation will only gradually self-destruct, and the process will begin from the surface layers. According to consumers, in a year the reinforced layer will become thinner by 1 mm. If you apply liquid glass with a layer of up to 5 mm, then the material will completely lose its properties in the tenth year.

However, users emphasize that waterproofing can be provided with a longer service life if it is covered with protective paint. When consumers use liquid penetrating waterproofing for concrete, they emphasize another nuance that can be called minus and plus. It is expressed in instant crystallization. The solution must be applied very quickly, otherwise it will seize and will not be suitable for work. If you do not have practice, then it is better to entrust the matter to a professional, since the material can simply be spoiled.

Fast setting becomes an advantage, according to buyers, when it is necessary to cover a concrete pool basin located close to groundwater. In this case, we are talking about structures that manage to fill with water in one evening. In wet conditions, waterproofing work can not be carried out with every material, to be precise - only with liquid glass. In 4 hours, the surface will dry completely and form an impermeable film.

If you decide to use liquid glass for concrete waterproofing, you must read the instructions. From it you can find out that using given material it is important to follow the dosage. If you mix the material with a composition similar to a concrete mixture, then there should not be an increased dose, since the solution will turn out to be “oak” and will not adapt to the design. In this case, the seams will be torn, as well as the joints. In addition, according to consumers, the coating will be unstable to damage, and cracks will appear if it is accidentally hit.

Liquid waterproofing for concrete is one of the most effective. If you decide to use liquid glass, then you can apply for application:

• brush;
• roller;
• brush.

Depending on what the final goals are, you should choose the proportion of the mixture.

When it is planned to lay on top of the laid layer roll material, then the waterproofing is done superficially. To do this, the glass is diluted with concrete and applied with a brush or spray gun in two layers. The mixture will penetrate into the foundation by 2 mm, filling cracks and micropores.

Liquid waterproofing for concrete can also be used when the foundation is prefabricated. In this case, it is required to isolate the seams using a composition of cement and liquid glass. To create a durable monolithic foundation liquid glass should be added to the solution. It is important to consider the dosage, otherwise the strength of the structure will suffer. The pouring of the foundation should be carried out by several people who will develop the mixture until it sets.

Sometimes liquid glass is used for In this case, work is usually carried out to restore the foundation, which began to collapse during operation. To do this, holes are made in separate parts of the structure using a perforator, and then the prepared mixture is injected inside. It is unlikely that there will be specific equipment in the house, so such work is usually trusted to professionals, and it is easy to overdo it with the dosage.

Features of applying liquid rubber

Liquid waterproofing for concrete is offered for sale in the form of rubber. This is a ready-made composition that is applied with a roller or brush. Mixtures are cheaper if they are intended for application in several layers. It should be remembered that after opening the package, the rubber will not be stored, so it must be used up immediately. This waterproofing technology is time consuming and not able to provide deep penetration.

You can use a two-component compound, such as bituminous emulsion, which is mixed with polymers at work and applied by spraying. This will require special equipment. The composition is clogged by pressure into the base firmly enough. This allows you to reduce material consumption, and if you carry out work by spraying, you will have to use the services of specialists.

Features of liquid rubber

The price of liquid waterproofing for concrete will be mentioned below. However, cost is not the only thing you need to know before purchasing a product. When choosing a solution to protect the foundation, you should pay attention to the features of liquid rubber, which remains elastic even after drying. This indicates that ground movements and shrinkage of the house will not affect the integrity of the formed layer. The material will only slightly stretch in those places where the foundation has cracked or shrink when displaced. If we compare rubber with liquid glass, then the latter does not have such abilities.

The cost of liquid waterproofing

The price of liquid glass for concrete waterproofing is 249 rubles. for 10 l. This is 15 kg of solution. As for liquid glass, 1 kg of material can be purchased for 155 rubles. The consumption of this waterproofing per square meter will be approximately 6 kg. Depending on the porosity, the indicator may vary. Sometimes it reaches 3 kg per square meter.

Conclusion

In order to achieve a positive result when waterproofing the foundation with liquid-type materials, it is necessary to familiarize yourself with the technology. For example, liquid rubber should only be applied to a dry surface, but manufacturers claim that the coating will dry even if the foundation remains wet. And for the material there is no difference - the base was dry or wet; the problem is that the water inside the foundation after the completion of the waterproofing work simply will not find a way out.

Hydraulic isolation of concrete with special compounds is important in the construction of new buildings, and the preservation of existing ones. At proper processing old foundations with protective materials from dampness, the buildings are still in operation for a long period. The most common drawback of old buildings is the corrosion of iron fittings. The applied means allow you to get rid of the disadvantage and operate concrete buildings longer.

Penetration into the finished structure of an aggressive environment and salt substances destroys concrete and iron from the inside. Therefore, additives in concrete for waterproofing can prevent such factors. Treatments are also used to achieve the same result on finished structures.

Description of the concrete waterproofing process

Penetrating concrete waterproofing uses a wide variety of preparations offered by the industry. But some of them have proven themselves better than others and are chosen by builders more often. Penetron concrete waterproofing belongs to the category of the most selected materials. She processes strategically important buildings, such as bridges, or rather their concrete part, which descends into water flows, concrete walls on embankments that protect cities from rising water in rivers. Also, the composition is able to protect the structure from temperature extremes and constant exposure to water. For a long time hydraulic isolation means were used, which covered only the surface with a protective layer in the form of a film coating, and with a small scratch, water flows seeped inside and continued their destructive property.

Now new tests have made it possible to create a material that is very different in composition from the previous ones, which, covering the concrete part, not only insulates it from above, but also penetrates inside, seeping through all possible ways, small capillaries and depressions. He, processing concrete, copes with corrosion and destruction.

Benefits of Penetrating Insulation

Penetrating insulation allows you to contain the impact on concrete of such factors as:
The high content of chlorine in water, which destroys the metal parts of the concrete structure and corrodes the metal,
Frequent wetting of a structure located on the street, exposure to concrete changes in the seasons, radiation during solar activity. Penetron, connecting with a concrete carrier, increases its density, which allows it to stoically resist the effects of aggression from nature.
The composition when it hits the recesses and small cracks, filling them, produces the process of overgrowing, that is, they are drawn in with the mixture and completely disappear.

How to work with a mixture of Penetron

Application building mix involves diluting it with water to the state of thick sour cream and applying it to a surface moistened with water in advance. You can spread the composition with a brush or roller. First, corners and places with grooves and cracks are processed. Then it is rolled over all the necessary part of the concrete.

When applied, the components of the creamy mixture penetrate into the thickness through the capillaries and recesses and clog them. When interacting with the concrete base, an impregnated crystalline crust is formed, which strengthens and makes the concrete durable. Crystals prevent the penetration of moisture, but freely pass air flows, which allows you to maintain a favorable atmosphere in buildings. Applied, the Penetron mixture can be used to treat external walls and in the middle of buildings, which will create a completely impenetrable protection.

In other words, it is an effective composition that comprehensively processes concrete and, in the event of any damage and cracks, the mixture tightens with the help of crystalline formations problem areas and the protection becomes complete again.

Liquid waterproofing method

Liquid concrete waterproofing is the next processing method. The adhesion of every millimeter is important point. Otherwise, what is the use of processing if it is not stuck on the entire surface and will have gaps.

This occurs when applying rolled hydraulic insulators, through which air penetrates in some places, followed by water.

The complexity of processing a concrete base is that it is difficult to make it even and rough, wavy surfaces do not allow for good hydraulic insulation. This is where the method comes to the rescue, in which full coverage is made and the impossibility of passes arises. Liquid rubber will cover the entire surface, both before leveling and after it.

To apply liquid hydraulic insulation to the floor, a preliminary screed is made, but only in order to save material. But in those cases when it is necessary to make hydraulic insulation inside the concrete, that is, to make it and fill and screed from above, liquid rubber is just what is needed.

The more curved the surface, the more difficult it is to make a complete hydraulic isolation, but this does not apply to the composition of liquid rubber, it freely covers up all structural errors.

Another important fact is that liquid rubber can be applied to a layer of concrete that is not completely dry. That is, the rubber composition applied to the concrete base, which was poured five days ago, will waterproof it and will not fall behind anywhere, and hydraulic protection can be made on the floor part already on the third day after pouring.

Bituminous and other insulators work only on a dried and cleanly cleaned substrate. Before applying, you need to check that there are no puddles left on the base, they are not visible to the eye, so you can run your hand and see if it is dry or not. If there are places where the hand feels a little moisture, you need to dry these areas. How to dry, you can get wet with a piece of foam rubber. If the hand does not feel moisture, and the surface is cold and slightly damp, you can spray rubber protection.

Rubber makes a complete seamless spacesuit over the entire surface. That is, when coated, there is not even a hint of any connecting overlap. There is a complete steam and hydraulic isolation. It turns out that the area treated with rubber is wrapped around from all sides. Excellent protection against moisture and gaseous substances.

Benefits of liquid rubber

Formaldehyde, causes minor damage:

• Hydrochloric acid, harms only at high temperatures,
• Hydrogen sulfide does not cause any harm.

Liquid rubber keeps concrete bases from water and chemicals, but does not keep from mechanical breaks. Therefore, usually a screed is made on top of the applied composition, if it is a floor, and a coating of other materials is applied to the sidewalls.

Waterproofing materials

If you need to hydraulically isolate concrete plates foundation from the outside, then in order to prevent damage, foam or insulation is placed on top of the rubberized base, and this is how backfilling is performed.

When waterproofing concrete, various materials are offered, consisting of mastics containing bitumen and polymers. Technoprok produces environmentally friendly and high quality mastic for insulating concrete surfaces.

Do-it-yourself concrete waterproofing can be done with Rapidflex and Technoprok liquid rubber brands. These are emulsion compounds that can be used to process basements and other concrete premises on their own, but using equipment adapted for this. Rubber compounds are not applied with brushes and rollers, they must be sprayed onto the surface so that the liquid is evenly distributed and adheres.

Materials for liquid waterproofing

To work with a brush on your own, you can use liquid rubber coatings, which are available in the form of a paste. Elastopaz or Elastomix materials have such a consistency that they can be worked with a spatula or brush.

In order for these rubbers to adhere well to the concrete base, its surface must be smeared with primers that will contribute to good adhesion of liquid rubber and concrete. Hydraulic sealing with liquid rubber compounds produces protection against water and radon.

When using the adapted equipment and spraying the room with rubber, the whole process is as follows. On a well-cleaned surface, vacuumed and free of debris, the application begins, layer by layer of liquid rubber.

During operation, it is advisable not to stop and spray in uniform stripes. All work should be done quickly, as the rubber compound quickly hardens and a solid crust is obtained.

Building protection

Protective work for concrete structures is simply necessary, whatever the concrete, with correct proportions batch, with the addition of an additive to concrete for waterproofing, using a variety of additives, without additional protective film, it will begin to deteriorate and collapse over time. Corrosive processes occur, but if you carry out additional work in terms of protection from them, concrete can serve for a long time.

Concrete buildings built by the ancient Romans have survived to this day, but, of course, now no one plans to build such durable buildings, but for 50-70 years you can keep the foundation in good condition.

When processing and hydraulic isolation in own houses special compounds should be used to close all kinds of cracks and treat corners. Mastic for waterproofing concrete will close access to moisture through small cracks formed during drying. The entire surface is treated with it before applying any type of hydraulic insulation, except for penetrating and using liquid glass. In all other ways, it will help improve the water-repellent work of hydraulic insulation, fill and level construction errors and prevent the concrete base from starting to collapse at joints and chips.

Liquid glass for waterproofing

There are several options for hydraulic isolation, which are used for work on large construction sites and for water protection of domestic buildings. Waterproofing concrete with liquid glass is one of the options. At home, it is used quite rarely, since the composition has the ability to quickly crystallize and solidify. Of course, sometimes when building pits for storing water supplies, liquid glass in a powdered state is added to the mixed concrete, before it is poured into the prepared and installed formwork. It is quickly stirred, and the composition is compacted in the formwork.

This supplement allows long time maintain the integrity of the concrete and prevent water from escaping. In addition, the added powder protects against the appearance of cracks through which water will seep, but such a pit is short-lived and will eventually have to be further isolated.

Construction teams use glass additives when kneading in special equipment, which makes it possible to prevent glass from crystallizing ahead of time and the prepared concrete will be more durable. There are also options for applying glass to the surface. There is sodium glass, which has increased stickiness and interacts well with mineral components. This category is used for additives in the foundation and in the manufacture of antiseptic and fire-resistant impregnations.

Potassium liquid glass is resistant to the effects of the atmosphere and is used in the manufacture of dyes. Liquid glass treatment is often used to protect architectural monuments made of concrete, since the applied glass covers the entire surface with a continuous crystalline film and water with the wind will not be able to destroy the statues. It is also used in places where a fire hazard situation may occur, and glass, unlike rubber, will not burn and retain a protective layer.

When adding liquid glass to concrete solutions, precautions must be taken. So that the concrete is not spoiled, a quick kneading and rolling or pouring the finished solution is necessary. Before adding liquid glass is diluted in a ratio of 1:2 with water. It can be added to the solution and simply sprayed from the spray bottle onto the surface. A layer of liquid glass will restore the weathered areas of the concrete base and create antiseptic protection.

Description of the work process

Before use, the entire surface is cleaned of dust, leveled and treated with degreasing compounds. For application to the surface, a spray gun is used, while the penetration of glass into concrete occurs by 1-2 mm. If it is necessary to increase the protective layer, then it is necessary to apply several times, thus increasing the penetration to 2 cm.

When processing wooden products, you can put it in a vessel with liquid glass, for complete coverage and impregnation. For basements, 1 liter of glass can be added to the plaster for every 10 liters of mortar. Liquid glass is used for hydraulic insulation of basements, screeds, wells and other buildings, as well as for corrosion protection of metal. Wooden floors are cleaned before treatment with liquid glass sandpaper. Before starting work, all surfaces are well cleaned.

There are several compositions that are used for hydraulic insulation. Now developed those that do not have a quick drying and can be used at home without the use of special equipment. These compounds are diluted with water in a ratio of 1: 2 and applied with a brush on a concrete base. The process is the same as for painting. The composition of the glass has such a feature that if the surface was not quite even, then the use of the composition will level it, the roughness will be removed and small cracks will close.

The use of a new composition of liquid glass makes it possible at home to make a quick hydraulic protection of basements, bathrooms, wooden buildings, concrete sewer drains and wells.

Concrete waterproofing

Concrete waterproofing is the process by which concrete surfaces such as floor slabs, walls, floors, etc. become waterproof. Exist various ways waterproofing devices.

Concrete

Concrete is construction material, consisting of cement, water, a number of fillers, reinforcing components, chemical and mineral additives. Sand and gravel are used as fillers, and reinforcement is mainly used metal fittings, as well as glass and plastic fibers. Chemical additives make it possible to obtain concrete with special properties. Mineral additives are used to increase the strength of concrete. In addition, admixtures can be used in place of Portland cement, which is usually the main ingredient in concrete.

Waterproofing systems.

There are 2 main systems for waterproofing concrete - this is a complex system for waterproofing and a system based on the use of waterproofing membranes.

The integrated waterproofing system includes 2 subtypes: hydrophilic and hydrophobic waterproofing systems.

Exist various methods hydrophilic waterproofing devices, the most common of which is a crystalline waterproofing device. This method is based on the transformation of the water contained in the concrete into insoluble crystals. The action of a number of hydrophilic waterproofing materials is based on their property, upon contact with water, to absorb it, expand under its influence and thereby fill the pores of concrete, making it waterproof.

Hydrophobic waterproofing systems are based on the use of various waterproofing coatings, membranes, etc., which are applied with outside isolated structures.

membranes

Waterproofing membranes are liquid and sheet. Liquid membranes are applied to concrete and form a rubber coating about 6 mm thick. The main advantages of this waterproofing method are high performance in use and low cost.

Sheet membranes are made from bitumen. These membranes are laminated polyethylene films and the sheets thus obtained are glued to the concrete. It is a very durable waterproofing material. Sheet membranes are used for waterproofing foundations, underground parking, tunnels, etc. The main disadvantage of sheet membranes is that they are glued by hand,
leading to higher labor costs.

hydrophobic concrete

Unlike hydrophobic membranes, "hydrophobic concrete" represents a completely new advanced technology. It is not based on the waterproofing of ready-made concrete structures, but on the production of waterproof concrete. Hydrophobic concrete is obtained by introducing special additives at the stage of its production. These additives prevent capillary infiltration of water into the concrete, thereby making it waterproof. Such concrete is successfully used in Asia, Europe and Australia and has proven itself among builders, as it allows to produce construction works even in the rain.

Crystal waterproofing for concrete

Crystal waterproofing device is one of the device options integrated system waterproofing. Let's look at how this is done. First of all, the area of ​​the concrete surface on which the waterproofing device is to be made must be moistened with water, then applied with a primer layer from a low density solution, and then covered with a crystalline waterproofing material, which is a high density solution. After that, the chemical diffusion process begins. The high density crystalline waterproofing solution penetrates the concrete to the low density solution until equilibrium is reached. After water enters the concrete, the hydration of the cement begins. The hydrated cement reacts with the crystalline waterproofing material contained in the concrete. During the diffusion process, the crystalline waterproofing material penetrates into the concrete to a depth of up to 30.5 cm. This method of waterproofing is very effective, since the crystals formed in the concrete are protected from any external damage. Another advantage is the heat resistance of the structure in an unchanged state up to 130 degrees. In addition, when waterproofing is installed, the resistance of the structure to such a chemical reaction as carbonization increases, as a result of which leaching and destruction of concrete is reduced; the diffusion of chloride ions into the structure is prevented, which in turn protects the reinforcement embedded in the concrete from corrosion and expansion.

Injection waterproofing of concrete

In some cases, when repairing concrete structures, technology is used. This method is based on filling the resulting shrinkage cracks with polyurethane or epoxy resins. Less often, they resort to the introduction of cement-containing injection materials. Injection waterproofing is recognized as the most effective and fast way repair of concrete structures from leaks. With its help, you can stop a strong infiltration of water in a matter of minutes. The disadvantage of this technology is the high cost of the applied waterproofing materials.

Before proceeding with the waterproofing device concrete...

Penetrating waterproofing for concrete is a mixture that is used to protect foundations and other parts of a building from moisture. It is used in both private and industrial construction. The composition of such a mixture includes cement, sand, as well as various chemical components. Penetration depth active substances inside the concrete is 10-12 cm. This allows you to reliably protect the foundation from moisture and extend its service life.

Concrete blocks, which are part of the foundation, are exposed to moisture throughout the operation. Atmospheric precipitation contributes to the erosion of the base of the building, which can lead to serious consequences. Concrete has microcracks through which moisture penetrates, getting into the basement.

It is also worth noting that water passes not only through microscopic cracks in the concrete structure, but also through the seams that are located between separate elements designs. These places are vulnerable and also need reliable protection. Brickwork does not have independent resistance to moisture.

In order to protect the foundation or any other structure (for example, a garage floor made of cement), it is customary to use a penetrating waterproofing for concrete. It is most often applied at the stage of building a house. But in the case when the house has already been built and there is a problem with moisture in the basement, then waterproofing is applied from the inside.

The principle of operation of the protective composition is simple and clear. After its application to concrete, the process of absorption of chemical additives through microcracks begins. In case of contact with water, the mixture that filled the capillaries of the block crystallizes. Such crystals fill the empty space and prevent the subsequent penetration of moisture. It is important to note that they do not dissolve in water.

Useful information! In addition to waterproof qualities, such impregnation strengthens concrete material making it more durable and wear resistant.

To apply such a mixture, a wet surface is required, which distinguishes it from roll coatings and mastic based on bitumen. Before you buy penetrating waterproofing for concrete, you should clearly understand the principle of its operation.

Penetrating mixtures protect the foundation not only from moisture, but also from the occurrence of mold and fungi. The process, which is based on the interaction of free lime and moisture, allows you to reliably close the pores in the concrete structure and protect the structure from destructive factors.

When is concrete waterproofing used?

To speed up the process of penetration of waterproofing substances into the concrete material, it is necessary to apply the composition on a wet surface. This method is very popular in cases where it is necessary to reconstruct the premises. Penetrating compounds are often used when there is no possibility to apply another method of protection.

Penetrating substances are actively exploited to protect the foundations of private residential buildings from moisture. Industrial building are also included in the list of objects that are treated with this type of waterproofing. Objects exposed to high humidity:

• cellars;
• wells;
• pools;
• bathrooms.

This waterproofing material for concrete is not very popular, as some people simply do not know about its existence. However, the application of bituminous mastics is accompanied by certain difficulties, since they harden very quickly. In turn, rolled materials do not guarantee one hundred percent protection of concrete from the damaging effects of moisture.

The main characteristics of penetrating waterproofing for the foundation

Waterproofing of any structure can be carried out at the construction stage. Moreover, many experts recommend using this particular method. It takes into account the addition of dry matter to the cement mortar. Such a mixture affects the structure of the future foundation, waterproofing properties which appear from the very beginning.

Additives in concrete for waterproofing help protect the foundation from the effects of precipitation and water in the soil at all points without exception. The operational life of this insulation will be equal to the shelf life of the foundation itself, since they are a single whole.

Note! Crystals that form in microscopic pores are resistant to water. They can be destroyed by letting water through, but even in this case, they are restored over time. Regeneration of this type allows for a high degree of protection of the foundation.

Advantages of penetrating waterproofing for the foundation

An important advantage of such additives is their ability to speed up the process of building a house. This is due to the fact that their use eliminates the need to dry the concrete. Thus, there is a time saving due to the penetrating waterproofing for concrete. Reviews of such compositions are mostly positive.

When applying the mixture to a concrete surface, you need to know that it must be wet. Moreover, the higher this indicator, the faster the crystallization reaction occurs inside the pores. The material itself does not lose its properties after processing, retaining all useful technical characteristics, such as:

• breathability;
• vapor tightness;
• resistance to temperature fluctuations;
• mobility.

The only indicator that undergoes a change after applying waterproofing is water resistance. This isolation is the most acceptable solution in the case when it is necessary to protect the foundation of an already finished structure from moisture. This is due to the fact that it eliminates the need to excavate the foundation. You can buy waterproofing for concrete in a specialized store or place an order via the Internet.

The penetrating composition provides reliable waterproofing protection, regardless of which side it was applied to the foundation. Pressure ground water in this case also has no effect on the quality of protection. The insulated surface, as well as all seams and butt points, become immune not only to moisture, but also to an aggressive environment with different Ph values.

Penetrating waterproofing for concrete: disadvantages

Any of the existing isolations today has some disadvantages. High Performance penetrating compositions make them the most suitable for protecting foundations and other structures, but they are not ideal. The main disadvantage of such mixtures is that they are recommended to be used in combination with other waterproofing agents. For example, to protect the seams of the foundation from moisture, it is recommended to purchase a special substance designed for this.

Another disadvantage of penetrating water insulation is that it is quite expensive. Depending on the brand and specialization of the mixture, the price of concrete waterproofing can vary from 50 to 350 rubles. for 1 kg.

Note! As a rule, insulation of this type is sold in bags weighing 25 kg.

Before starting work on applying such a composition to the surface, it is necessary to carry out preliminary training. It is very important to clean the wall so that no (even minimal) contamination remains on it. Otherwise, the composition will not be well absorbed into the material. It is also worth degreasing the surface in advance. Experts recommend using a garden hose to clean the wall, as the water coming out of it under pressure does a very good job of this task.

The cost of waterproofing material can vary greatly depending on its type and brand. most economical and reliable option- penetrating waterproofing Lakhta. You can buy such a mixture for a very reasonable price (80-100 rubles per 1 kg).

All of the above manipulations are necessary in order to provide free access to microscopic pores. In the presence of large gaps and cracks in concrete walls they need to be eliminated. It is recommended to cover up such defects with cement mortar. This option is the most acceptable and simple.

It is also worth noting that waterproofing mixtures of this type do not work if used to protect the surface of the brickwork. With their help, you can only protect and strengthen the seams in such a design. Thus, for brickwork it is better to use more common and familiar protection options.

However, taking into account all the disadvantages, today there is no more effective remedy for waterproofing concrete structures. Before buying this composition, it is recommended to study the companies that are engaged in its production. This will allow you to choose the most reliable means for a very reasonable price.

Penetrating waterproofing: an overview of popular brands

Currently, the construction market is replete with various materials designed to protect the foundation. Penetrating insulation for concrete is also no exception. It is implemented by different companies, each of which has its pros and cons. Experts do not recommend buying the cheapest formulations, as they most often are not of high quality.

The average price range is the most acceptable, as it includes good, high-quality brands of compositions. When choosing necessary funds the seller should be consulted. And also before you buy a penetrating waterproofing, it would be useful to study reviews about it on the Internet. To date, the following brands of penetrating mixtures are the most common and effective:

• Penetron;
• Lakhta;
• Kalmatron.

The first option is the most common. It has been used for about half a century around the world. Lakhta is distinguished by a variety of choices. And the Kalmatron brand mixture is considered the most versatile penetrating waterproofing. Pools, wells, cellars and balconies - all these structures can be protected using the products of this manufacturer. There are many other brands that differ in their composition, application and action. However, the above companies have proven themselves best in the production of products for the protection of concrete structures.

Penetrating waterproofing Penetron: characteristics

Building compositions of the Penetron brand are used not only for private, but also for industrial purposes. These mixtures appeared a long time ago, and the effectiveness of their use has been tested by time. The composition of this mixture includes sand (quartz) and active chemical compounds.

The cost of such a penetrating composition is quite high - 250-300 rubles. for 1 kg. However, its technical characteristics fully justify such a price. Penetrating waterproofing Penetron allows you to protect not only the foundation, but also walls, as well as floors made of concrete. The consumption of Penetron is quite simple to calculate, since about 1 kg of composition is required to protect 1 m².

Note! Be vigilant, as domestic markets are filled with various kinds of fakes, which can cost much less than the original. The quality of such mixtures is in question, so you should not save on waterproofing the foundation and other concrete structures.

The penetrating waterproofing for concrete Penetron is used for protection against water of wells, pools, a floor and walls in bathrooms and garages. Before using such a composition, it is advisable to read the instructions and watch the training video, which will describe in detail all the nuances of the work.

Features of penetrating waterproofing Lakhta

The Lakhta brand is domestic, and its distinguishing feature lies in a wide range of dry mixes used for concrete waterproofing. The products of this brand are used for various tasks, including to enhance the water resistance of seams.

The principle of operation of such mixtures is the same as in the case of Penetron waterproofing material. Active chemical components penetrate into the pores of the concrete structure and crystallize when interacting with water. Before proceeding with the application of Lakhta waterproofing, it is necessary to prepare the concrete surface.

The cost of this mixture is lower than the previous composition, but the products have quite good feedback. The price for 1 kg of the substance is approximately 120-180 rubles. In terms of technical characteristics, such insulation is practically in no way inferior to the composition of Penetron. The price of penetrating waterproofing Lakhta determines its popularity and prevalence in construction market.

This mix is ​​used for protection against moisture of concrete designs of industrial and household value. With the help of such waterproofing, you can increase the water resistance of walls and floors in the cellar or garage. And also it is actively used to protect swimming pools, bathrooms and balconies.

Penetrating waterproofing Kalmatron: price and properties

The composition of this brand allows you to quickly and effectively eliminate small leaks that destroy the foundation of the building. This mixture helps to increase the strength of the surface of the concrete material. A feature of the Kalmatron waterproofing substance is its versatility. Compositions of this type are used to isolate the following materials from moisture:

• concrete;
• reinforced concrete;
• bricks;
• foam concrete;
• aerated concrete.

The price of penetrating waterproofing for concrete of this brand is the most attractive of all the brands presented. The cost of 1 kg of the product is about 80-100 rubles. Thus, for a bag with a volume of 25 kg, you will need to pay approximately 2000-2500 rubles. Such compositions can be used both during the construction process and during the operation of concrete structures. Domestic consumers note the rather good waterproofing properties of Kalmatron compounds.

Useful information! Before purchasing this waterproofing material, one important point must be considered. It is not recommended to use it if the Ph level on the object is in the range from 3 to 11.

Liquid waterproofing for concrete: characteristics

In addition to dry mixes, there are other ways to protect concrete structures from the harmful effects of moisture. One of them is the use of liquid waterproofing. Today you can find a variety of composition liquid materials of this type, but the following are the most common:

• liquid rubber;

These materials have both advantages and disadvantages. Before purchasing one of them, it is recommended to study the features of their use. Liquid products are much easier to work with, especially when compared with bituminous mastics, membrane films and roll products.

You can buy liquid waterproofing for concrete on the construction market, in a store or on the Internet. The cost of such formulations is about 2 times higher when compared with dry mixes. Liquid substances that provide waterproofing to concrete are also convenient in that they can be applied to uneven surfaces.

The nuances of using liquid waterproofing for concrete

The process of applying a protective composition is quite simple. It does not involve heating the mixture, as is the case with bituminous mastic. It is also worth noting that the quality of this type of waterproofing is very high. Among other advantages of the liquid mixture, one can single out the fact that it does not cause any harm to human health, since it does not emit active chemical compounds.

Liquid water insulation is resistant to high temperatures, so in summer period do not be afraid that it will start to melt. Such material is an excellent alternative to rolled and other insulators.

Liquid glass for concrete waterproofing is applied using the following tools: brush, construction roller. The viscosity of the composition resembles the density of PVA glue. Such a mixture is applied in a thin layer, which, after drying, requires additional protection. This is due to the fact that the finished layer has a weak resistance to mechanical stress.

Penetrating insulation of this type allows you to achieve excellent results. Impregnations based on dry mixes increase water resistance, and liquid compositions make the concrete structure practically invulnerable to water. But this method also has some disadvantages. For example, it is quite difficult to make a layer of the required thickness with your own hands. Therefore, it is better to use the services of a professional.

Characteristics of coating waterproofing for concrete

Many people confuse impregnation with coated insulation. This is not surprising, since they are very similar in their properties. Both of these types of waterproofing must be applied to the surface of the structure, after which they penetrate deep into the concrete through microcracks. The difference between the impregnation and the coating mixture is that it protects the concrete from moisture, penetrating quite deep into the blocks. In turn, the coating mixture makes only the concrete surface waterproof.

Useful information! Penetrating coating waterproofing is absorbed into the concrete material shallowly, just enough to ensure reliable and effective adhesion to it. This is the main difference between impregnation and coating.

A very important point is that a layer having such a small thickness must be applied correctly. Otherwise, it will not cope with its functions.

requirements for modern coating materials, which provide impermeability of concrete to moisture, are very high. It is important to note that in the case of applying a waterproofing agent from the side that resists the movement of moisture, claims to the material increase. This is due to the fact that it must withstand the pressure of the fluid. This composition must have the following characteristics:

• good adhesion;
• water resistance;
• elasticity.

The latter characteristic is very important, since the concrete foundation wears out over time and cracks appear in it. In such situation good remedy coating type must not be damaged.

Features of waterproofing paint for concrete

Watertightness of concrete can be achieved with the help of another means. They are waterproofing paint. It has many benefits. For example, it is very easy to apply it on the surface yourself, which makes it popular among people.

Depending on the amount of constituent substances that make up such a paint, it can be one-component or two-component. Paint, which has a water-repellent effect, is most often a one-component. This composition is enamel and is distinguished by high technical specifications. If desired, it can be used as a seam penetrating waterproofing.

These compounds have a high degree of waterproofing, so they are most often used to protect the walls of pools and other tanks that are constantly in contact with water. The application of such paint is carried out by means of special spray guns. Thus, it becomes possible to independently regulate the jet leaving the tool.

Features of applying concrete waterproofing

The application of waterproofing material for concrete is carried out strictly in accordance with the instructions. This process is conditionally divided into several stages. Experts do not recommend retreating from them. Of course, it is much easier to use additives in concrete for waterproofing, but water insulation is not always done at the construction stage of a building. Consider the algorithm of actions that you need to focus on when working with waterproof compounds.

First of all, you should prepare the surface on which the penetrating material will be applied. The surface is thoroughly cleaned, after which it must be degreased. And also it will be necessary to carry out a preventive check of sewage communication. It shouldn't have any damage.

Useful information! If you want to waterproof a surface that is many years old, then removal may be required. old cladding. After that, a layer of plaster is applied. In some situations, it may be necessary to organize new reinforcement.

The places that match the seams require special attention. They should be carefully punched. The same applies to wide cracks (more than 4 mm). Finished channels are sealed using special sealing compounds. It is very important not to forget to close the slots at the points corresponding to the passage of pipes through the wall. For this, sealants are also used.

It should be noted that for the organization of penetrating waterproofing of the floor, the algorithm of actions will be somewhat different. In this case, the work is simplified, since the need for chasing the seams disappears. But in general, both processes are similar to each other, since they involve careful surface preparation and application of the composition of the most convenient way in accordance with the instructions.

The next step is to prepare a solution of penetrating water insulation. In this case, it is necessary to carefully study the instructions, which describe all the dosages and the method of using the mixture. Next, the composition is applied to a previously prepared surface. For this, different tools are used, such as a brush, roller or a special spray gun (depending on the properties of the waterproofing mixture).

Penetrating agents are modern means, which allow you to make the foundation waterproof, thereby increasing its service life. These mixtures can be very different from each other, but they all do their job better than traditional materials for guard concrete structures. When choosing a penetrating waterproofing for building foundations, as well as other concrete structures, it is necessary to pay attention to its price, composition and method of application.

According to building codes, concrete waterproofing is carried out to protect against the damaging effects of moisture.

Concrete structures are widely used in civil and industrial construction.

Many of them, such as a foundation or a well, are hidden by the ground, the other part is located in open space.

In both cases, concrete is exposed to external influences from which protection is required.

What is waterproofing for?

Concrete is an artificially created material that is not inferior to natural materials in terms of basic parameters.

These properties formed the basis for wide application concrete in the construction industry. Concrete has the necessary strength and durability.

Concrete consists of two main components - a binder and a filler. In the construction of residential buildings and factory buildings, cement is most often used as a binder.

The filler can be crushed stone, gravel and sand. In addition to traditional components, special additives are used in concrete for waterproofing.

New technologies for waterproofing concrete increase its resistance to the damaging effects of moisture.

Sometimes it is enough to add certain remedy in concrete mix to provide the required specifications.

Today, the following methods are used in construction for applying waterproofing:

• application of coating materials;
• painting with liquid insulating mixtures;
• impregnation with penetrating substances.

There are other ways to protect concrete from moisture damage. This must be done with knowledge of the essence of the processes that occur at the molecular level.

To understand why concrete waterproofing mixes are needed, you need to know chemical formula cement.

Without going into detailed description process, it is enough to bring the main ingredients of this substance - calcium oxide, silicon dioxide and aluminum oxide. In its original form, cement is a fine powder.

It is important to emphasize that the powder is very hygroscopic, in other words, it actively absorbs moisture from the atmosphere. Instructions for the storage of cement prescribes to protect it from moisture.

When cement is combined with water, a chemical reaction occurs, as a result of which the powder becomes a hard stone that serves as the basis for concrete.

Foundations and structures made of concrete gain design strength gradually.

It is important to emphasize that concrete does not "freeze" and does not "seize". These terms have the right to be used, but do not reflect the essence of the ongoing chemical reactions.

Concrete reaches its maximum density after all the cement has reacted with water. With further moisture fake diamond will gradually break down.

To prevent the degradation of structures, mastic is used for waterproofing concrete and other materials. Reliable protection can be achieved by coating concrete surfaces with liquid glass.

If the waterproofing of concrete is performed in violation of technological regime, then moisture will constantly fall on its surface and gradually penetrate inside.

In this case, the penetration of moisture entails very serious consequences.

First, the binder is washed out of the concrete monolith, in other words, petrified cement.

Secondly, as a result of contacts between moisture and reinforcement, the process of metal corrosion begins. After some time, the reinforcing frame loses its strength.

So that concrete buildings and structures do not collapse before the standard period, moisture should not penetrate into the body of concrete blocks. To do this, a waterproofing layer should be applied to the concrete.

Concrete waterproofing materials

Today, in the construction of facilities are used various technologies and materials for concrete waterproofing.

Among the most effective are the following substances:

• viscous and liquid formulations;
• roll and tile coatings;
• penetrating mixtures.

The application of any waterproofing to concrete is carried out according to certain rules. Coating a concrete surface with liquid glass is carried out in the same way as painting.

Viscous materials are preheated and applied with a spatula. Combined methods are used for more reliable waterproofing of concrete surfaces.

Liquid and viscous waterproofing

In order for liquid waterproofing for concrete to perform its functions, it is necessary to strictly follow the rules for handling this material.

When processing concrete with liquid glass, the insulating composition penetrates into the smallest cracks and creates a water-repellent surface layer.

The protective film is firmly connected to the concrete base. It is important to note that liquid glass, as a rule, covers surfaces to which there is easy access.

In some situations, in order to prevent the destruction of the protective layer, it is reinforced with a coating of another material. Most often, a polymer membrane is used for this purpose.

It is possible to apply a waterproofing layer on concrete only after careful preparation of the surface.

This requirement must be met not only when working with liquid glass, but also when using viscous mastics. Coating waterproofing for concrete, it is most often prepared on the basis of bitumen.

The mastic layer is applied to the previously primed surface. As a primer, an emulsion based on a solarium or kerosene is used.

The mastic is applied with a brush or sprayer. To increase the reliability of waterproofing, the protective composition is applied in two layers and reinforced with a polymer mesh.

Roll materials

When pouring floors in a garage or industrial premises, waterproofing must be laid under concrete. At such facilities, material is used in rolls or slabs.

For these purposes, roofing material is still most often used. Liquid glass for waterproofing in such situations is not suitable.

When waterproofing deep foundations, the roofing material is glued in several layers. Experts note that this is a laborious procedure.

In recent years, roofing felt has been replaced waterproofing materials based on fiberglass, which are characterized by increased strength and long service life.

Fiberglass, impregnated on both sides with a bitumen-polymer mixture, sprinkled with mineral chips on the outside.

During recent years this type of waterproofing is used to protect concrete roofs from moisture. It is impossible to work with liquid glass on such objects.

Penetrating waterproofing has a high cost and does not justify the expected costs.

The technology of waterproofing concrete with rolled materials is well developed, performed quickly and lasts a long time.

To complete the work, you only need gas-burner and a wooden ironing board. The surface is thoroughly cleaned before laying the waterproofing.

Penetrating agents

New materials and technologies appear regularly in the construction industry. Penetrating waterproofing for concrete is a good example of this.

The principle of operation of this mechanism is that special crystals penetrate into the cracks and pores of the concrete structure and clog them.

This blockage occurs as a result of the growth of crystals. In turn, growth begins when the source material comes into contact with water.

In this way, the concrete base is strengthened. This method is used to repair dams, in cases where the level of concrete filtration exceeds the established norms.

When waterproofing concrete with a penetrating method, it is very important to follow the instructions for using the preparation.

The waterproofing composition is available in the form of a powder, liquid or mastic. The first step is to dissolve the powder with water in the proportion indicated on the package.

Then within 7 - 10 minutes it is necessary to apply the solution on the concrete surface in two layers. The surface must first be wetted.

If the first layer is applied horizontally, then the second one is applied vertically, and vice versa. The final fixation of the solution occurs after three days. During this period, it is recommended to spray the concrete with water.

Scope of application

When preparing concrete waterproofing, the materials must be selected in accordance with the problem.

Many objects lose their original characteristics over time and require current or major repairs.

AT Everyday life often there is a need to carry out additional waterproofing of the basement.

Dampness in basement may occur as a result of rising groundwater levels.

In this situation, penetrating type waterproofing would be the most appropriate method of protection.

The added component must be properly prepared and the procedure for additional waterproofing must be carried out strictly according to the instructions.

Concrete waterproofing works are divided into vertical and horizontal. It is more convenient to apply mastic and roll materials on walls.

For multi-layer waterproofing, polymer membranes, roofing material and fiberglass-based roll material are used.

When applying waterproofing to concrete floors and roofs, impregnating materials are used.

It should be noted that there are no strict restrictions on the use of a particular type of waterproofing for horizontal surfaces.

A particular type of waterproofing material has a universal application.
