Strip foundation drawing

Reinforcing the foundation is not an easy procedure, and it can be difficult to take into account all the nuances correctly. But if you follow all the instructions for reinforcing the strip foundation, watch a video on the topic, it is still possible to deal with it yourself. One of the important stages of construction is the calculation of the base.

Features of the strip foundation drawing

The tape base is a concrete tape that runs around the entire perimeter of the future building. It is most often used in suburban construction, as it allows you to build a foundation in a short time on any type of soil. This type of foundation is universal.

The tape base can be used:

  • for buildings made of concrete, brick and stone;
  • for buildings with heavy overlap (prefabricated reinforced concrete or monolithic, metal);
  • if the site consists of different types of soil (for example, one part is sand, and the other is heaving loam);
  • if a basement or basement is planned in the building.

Strip foundations are divided into: prefabricated, monolithic, rubble.

At the planning stage, it is necessary to correctly select the necessary elements for reinforcement and their quantity. So it is recommended to draw up a detailed drawing of the future foundation with the selected scheme. If you make a mistake at the design stage (saving building material, designing the structure incorrectly, completing an inaccurate drawing), this can subsequently lead to negative consequences.

Most often they encounter such problems that arise due to an incorrectly executed drawing:

  • skew;
  • insufficient amount of material;
  • deformations of various kinds;
  • uneven precipitation;
  • the appearance of cracks, etc.

Calculation of the number of elements, a correctly executed drawing and following it at all stages will allow you to build a strong and durable structure. In order to calculate the amount of reinforcement for a strip foundation, the easiest way is to use an online calculator or a special program.

Depth

In order for such a foundation to function for a long time, you need to lay it at the right depth. To do this, it is necessary to study the type of soil and the distance at which it freezes.

Distinguish between shallow and deepened type of foundation. The first type is used for construction on heaving and slightly heaving soils. This is the most common option used in suburban construction. The cost of its construction is only 15-18% of the total cost of construction.

In turn, the deepened foundation is stable and durable. It is also suitable for two-story buildings. Accordingly, this is a more costly option. The depth of the buried base is calculated by the formula freezing depth plus 10-20 cm. Of course, the more floors, the deeper the foundation is required. It also depends on the type of soil. If the soil is good, the depth can be reduced. For a light one-story house, a shallow base is more often used.. The depth of the foundation for a two-level house made of foam blocks reaches 50 cm.

Strip foundation reinforcement scheme

Reinforcement of the strip foundation is a crucial stage on which the life of the building depends. Reinforcement of shallow and deep foundations differ slightly. In the first case, it is much easier to strengthen the base. In addition, you can plan a small basement. It is suitable for building the foundation for most wooden buildings: cottages, bathhouses, agricultural buildings.

A recessed type of foundation is laid under houses made of stone with single concrete floors. or in buildings in which several floors and basements are planned. Of course, in this case, large financial investments will be required.

Since the foundation experiences significant loads during operation, it is necessary to reinforce both the upper and lower parts. And if its height exceeds 150 mm, it is necessary to install more steel rods in the transverse and vertical directions. It is necessary to strengthen the foundation with hot-rolled reinforcement, the diameter of which is from 6 to 8 mm.

Working fittings should be 10 to 20 mm in diameter, and auxiliary fittings - from 6 to 10 mm. Reinforcement bars are overlapped to prevent layering. Connect the transverse rods with longitudinal special clamps. Longitudinal reinforcement should be placed inside the prefabricated frame. After installing the rods, they must be connected. This is done so that in the future cracks and chips do not form on the foundation.

The distribution of reinforcement is carried out in accordance with building codes SNiP 52-01-2003. This provision indicates that the distance between vertically arranged rods is calculated based on the concrete filler and the method of its laying. The rule regulated in SNiP 52-01-2003 indicates the norms for laying longitudinal rods: the distance between them should not be more than 40 cm.

Methods for fastening parts of reinforcement

There are two ways to connect rods: welding and knitting. In individual construction, wire knitting is most often used, in mass production - welding. It is preferable to use knitting also because the places where the reinforcement is fastened by welding are subject to corrosion, losing strength and reliability of adhesion. Welding of reinforcement is permissible if the bar is marked with the letter "C".

Basic principles of foundation reinforcement

First, rods of small diameter are driven in in increments of 50-80 cm. Their height should not be more than the height of the formwork. A brick is laid at the bottom of the trench, which will be a support for the lower tier of reinforcement. Then a metal rod is fixed at a certain height from the soil.

It is necessary that the frame is at a distance of 5 cm from each side of the trench. It is in this case that the reinforcement will be completely immersed in concrete. In order for the supports to be even stronger, a sand cushion is installed.

The technological sequence is as follows:

  • at the bottom of the pit, sand is poured with a height of at least 10-20 cm;
  • carefully rammed;
  • sprinkled with water.

When the sand dries, it usually takes 2-3 days, geotextiles are laid on the pillow.

Depending on the type of soil and the height of the future building, the size of the sand cushion may increase. In some cases, the size of the sand cushion reaches up to 80 cm..

Basic rules for reinforcing a monolithic foundation

To reinforce a monolithic foundation, from 2 to 4 rods are required in the lower belt and the upper belt. They are folded into a structure resembling steps and reinforced with a special rod mesh.

Reinforcing bars should be 10-12 mm in diameter. Subsequently, it depends on how they will be fastened - by welding or viscous. To give the structure solidity, the rods are laid in two directions and placed below the bearing floors or columns.

The reinforcing elements are installed after the formwork is completed and connected to each other with wire. Then a grid is laid on top of them. It should be noted that the structure, together with the mesh, must be at least 7 cm from the ground.

Reinforcement of the sole of the strip foundation is carried out using a mesh that is laid below the pillow. The dimensions of the frame cells should be 20 ... 30 cm. Moreover, it is better to use whole rods that do not have any connections.

Features of fiberglass reinforcement

Reinforcement of the strip foundation with fiberglass reinforcement is not much different from metal. The main difference is that in this case it is easier to reinforce the corners. The service life of this reinforcement is much longer than steel. In addition, there are no problems with the appearance of corrosion. The weight of the rods is also much less, so all work can be completed faster.

Features of the formwork device

During the formwork assembly, it is necessary to ensure that the reinforcing bars do not touch the ground, because. this will accelerate the occurrence of corrosion. The layer of concrete solution that protects the reinforcement should be at least 5-8 cm.

One of the important stages is the reinforcement of the corners of the foundation, because. she will be under the most pressure. If the reinforcing work is not done correctly, then the entire building will lose stability, and the reinforcement bars will not be able to cope with the pressure.

The corners are made from rods of class A3. One side should overlap the other by approximately 50-70 cm. Reinforcing bars that are inside the corners must be in contact with the outer parts of the reinforcement.

The reinforcement of the decorative part of the base (bay window) and the T-shaped elements of the adjoining elements is also performed. These vulnerabilities are reinforced with additional U-shaped or L-shaped fasteners.

Drawing of a monolithic strip foundation and its construction

Impossible without project documentation erection country cottage. For the construction of a garden house, a project is not required. However, without a sketch, it will not be possible to mark the building spot. Therefore, the owner of the site needs minimal knowledge in design, advice from professionals for individual stages of construction.

How to make a drawing of the foundation?

At the initial stage, it is necessary to determine the dimensions of the building, having received four axes of the outer walls. Then the axes of internal load-bearing walls, heavy partitions are added to the project, taking into account the following factors:

Then on the sketch it is enough to add two lines (inside, outside the perimeter) from the axes tape foundation. Formwork panels will be mounted along these cords, the string along the center lines will allow you to control geometry deviations monolithic foundation.

The simplest design method

When calculating individual elements strip foundation you will need tables SP 22.13330 or V.S. Sazhin's Guide. The technology for calculating the width of the tape has the form:

The depth of occurrence for the MZLF is 0.3 - 1 m, depending on the groundwater level. Buried tapes are lowered below the freezing mark by 0.4 - 0.6 m. The height of the basement part of the foundation depends on the preferences of the developer:

  • when pouring the tape at a level of 10 - 20 cm from the ground level, you can make a floor on the ground, drastically reducing the construction budget
  • when lifting by 40 - 60 cm, a ceiling on beams or a slab is used; ventilation ducts are required in the basement
  • if an underground floor is planned, the height of the basement depends on the level of the finished floor in it

According to the results of calculations, it is possible to make a drawing for the removal of axes in the building spot, for earthworks.

Strip foundation sketch

For accurate drawing monolithic foundation you need access to professional graphic editors AutoCAD, Compass, Solid Work, Archikad. Therefore, for garden buildings, paper sketches are more often used. On it it is necessary to mark the axes of the walls, auxiliary structures (stove, internal stairs, porch, fireplace), draw the contours of the foundation tape.

Reinforcement scheme

For anyone strip foundation reinforcement is necessary if it is intended to manufacture a monolithic structure in place. The layout of the lower, upper reinforcement cage can be shown in the same drawing. It will be needed to draw up an estimate when buying bars, wire, gaskets, stands. When drawing a diagram, you must consider:

With a belt width of less than 15 cm, one bar in each belt is sufficient. In wide tapes, the minimum distance between the rods (in the light) must be more than 35 mm (bottom), 40 mm (top). Reinforcement is needed in the lower part at the sole, near the upper edge of the structure. In the middle part, the tape is reinforced only at its high height (from 0.7 m).

Construction technology

For monolithic foundation a standard construction methodology is used, consisting of the following steps:

  • full-scale removal of axes
  • trenching / excavation
  • backfill padding
  • sole waterproofing
  • formwork installation
  • reinforcement
  • concreting
  • surface waterproofing

To reduce the heaving forces, the blind area is insulated, the side surface of the tape, drains are laid at the level of its sole. At each stage, there are nuances that allow you to reduce the amount of work, increase the resource of the structure.

Marking, pit

Before moving the axes into the building spot, it is necessary to place the building on the site for the normal operation of engineering systems, the fertile layer, and the dwelling itself. For example, parking is often present on the street side, the septic tank of the external sewer requires periodic emptying, therefore it is also located closer to the street. It must be at least 4 m from the foundation to provide a sanitary zone.

Power line poles, wells with shut-off valves for connection to central life support systems are also mounted here. The front facade is most often turned towards the roadway. After that, it is enough to markup strip foundation according to the scheme:

  • first wall - starting angle 3 m from the boundaries of the site, awn 5 m from the red line (street road)
  • side walls - perpendicular to the first axis (building a triangle with 4.3 m legs, 5 m hypotenuse)

The corners of the last wall (back facade of the house) are obtained automatically. During earthworks, the manufacture of a foundation cushion, the cord has to be removed periodically. To avoid repeated measurements, cast-offs are recommended - a horizontal bar between two pegs. They need 2 pieces for each axis, three strings can be stretched at once along wide strips (lateral faces of the foundation, wall axis).

Cushion, formwork

A layer of non-metallic material under the sole of the tape monolithic foundation designed to replace porous material, leveling the bottom of the trench. The most popular underlay scheme:

  • sand 20 cm + crushed stone 20 cm - laid on geotextile, wrapped with it on top after tamping every 10 cm
  • crushed stone + sand (similar thickness) - a more convenient option, an extra layer of geotextile is added between these materials, but you do not need to pour footing when laying rolled waterproofing
  • sand 40 cm or crushed stone 40 cm - the first option is only with low GWL, the second with high groundwater

Rolled waterproofing (usually hydrostekloizol) is laid in 2 - 3 layers with a release, so that after concreting it can be wrapped on the side edges of the tape. The formwork is mounted on top of it, it is better to use materials that can be reused (OSB, plywood, edged board).

Vertical shields, the height of which is 5 cm more than the design mark, are supported to the sides of the trench, the ground, fastened with jumpers (studs, bar). In the underground level, it is necessary to leave openings for the entry of engineering systems, in the basement of the ventilation duct. To do this, pipes are passed through the shields, which remain in the concrete for the sleeves or are pulled out during stripping.

reinforcement, filling

Aromoframework tape the foundation is usually two-level. For light buildings, two corrugated bars in the upper belt, two in the lower one are enough. To fix the rods inside the formwork, rectangular clamps are used, curved from smooth 6–8 mm reinforcement, to which longitudinal reinforcement is tied with wire. The main requirements are:

The lower rods rest on polyethylene pads or concrete pads to provide a protective layer. pouring takes place according to standard technology with a seal around the ring every 60 cm of concrete to remove air.

Waterproofing, drainage

For monolithic foundation, partially or completely submerged in the ground, protection from moisture is necessary. It is carried out in several ways:

A storm drain is built into the outer perimeter of the blind area (storm water inlets + surface trays), with the help of which thawed, rain runoff is drained.

The above technology is suitable for tape foundation of any type, deepening. The recommendations of specialists will help to avoid mistakes, reduce the complexity of construction operations. The dwelling will have a high operational resource, despite independent calculations.

Drawing of a monolithic strip foundation and its erection Without project documentation, it is impossible to erect a country cottage. For the construction of a garden house, a project is not required. However

Strip foundation plan, drawing

In private and commercial housing construction, a strip foundation is often used, the drawing of which in a simplified form is a top view with linear dimensions.

Scheme of the strip foundation.

Features of the strip foundation

The strip foundation belongs to the class of monolithic foundations, but is more economical than slab foundations. With a reduction in the consumption of concrete and reinforcing structures, such supports remain highly reliable for low-rise housing construction and are also used in the construction of fences, utility and household buildings of various types.

This type of foundation plan can represent two types of support structures:

  • monolithic, during the production of which the solution is poured into a trench with filling,
  • made with laying of finished reinforced concrete products.

The depth of the trench in both cases is greater than the level of soil freezing, and the width is calculated taking into account the load.

Rice. 2. A simple and understandable schematic representation of a monolithic strip support with dimensions.

Influencing factors

When performing engineering calculations, the following factors are taken into account:

  • the total weight of the structure (during the construction of buildings, the materials from which the construction will be made, the internal layout, the number of floors, the number and size of window and door openings are taken into account),
  • type of soil that affects the degree of shrinkage,
  • the magnitude of the load during operation.

Features of building a plan

The plan of tape-type supports is created according to certain rules.

  • The scaling is 1:100 or 1:400.
  • Before construction, axial marking is performed.
  • If there are columns, their location is indicated on the diagram.
  • The general outlines of the structure are applied in lines of 0.5-0.8 mm.

The full plan includes images of the footing and soles, indicating the places of depth differences characteristic of uneven surfaces, and openings for the entry of utilities. The latter can be represented in two ways:

  • with a full schematic representation and indication of data on the low point,
  • axial point by transferring the main data (diameter, parameters of the lower point) to the explication.

Communication holes and ledges are depicted by shading or contour, broken lines. If necessary, such images are clarified with explanations or footnotes.

Image of difficult areas

If the plan depicts a prefabricated or monolithic foundation of a complex configuration, it is difficult to convey the nuances of the device in a single complete diagram. In this case, more complex planning methods are used:

  • apply additional images of cuts to the main drawing, ensuring their axial correspondence,
  • if necessary, make such cuts larger, they are performed on separate supplement sheets indicating all the necessary data (numerical, explanations, arrows indicating the type of cut, etc.).

In accordance with the complexity of the sections, scaling 1:20, 1:25 or 1:50 is selected.

On additional sections indicate:

  • ground level,
  • floor level,
  • general outline of the supporting structure,
  • thermal and waterproofing.

Possible additions to the general scheme

If a monolithic or prefabricated strip foundation is planned, for the most complete information needed by the builders, the general plan is accompanied by:

  • a reinforcement scheme drawn up taking into account the load and geometric parameters (the reinforcement is laid in the lower and upper parts in the horizontal direction, with a total support height of more than 1.5 meters, additional vertical reinforcement is required),
  • notes containing information about the nuances of the design,
  • recommendations for preparatory work,
  • information about hydro and thermal insulation,
  • tables indicating the load standards for a specific supporting structure.

Degree of deepening

The depth of the strip foundation is determined in accordance with the purpose of the support. There are two main types of structures - buried and shallow. This feature is necessarily reflected in the plan.

  • Shallow types are used in the construction of small brick or concrete structures, as well as in the construction of wooden buildings on soils of a slightly heaving type. The depth of the trench in this case is 50-70 cm.
  • Recessed types of strip foundations with reinforced reinforcement are suitable for large houses that have basements or basements, heavy floors. The optimal depth of the trench is 20-30 m more than the depth of soil freezing.

Sectional drawing of a buried strip foundation.

The plan always contains information about the degree of penetration of the tape.

The consumption of materials for the implementation of buried supports is much higher.

Differences between the drawings of prefabricated and monolithic supports

The principle was described above, according to which a plan is drawn up for any strip foundation, whether it is monolithic or prefabricated. At the same time, the drawing, which shows the prefabricated type of support, has a characteristic difference - the images indicate the mark of whole and corner reinforced concrete blocks.

Independent calculations

Without experience and qualifications, it is not difficult to create a plan for supporting structures if the prefabricated foundation is calculated for outbuildings or fences. To do this, it is enough to take into account the following parameters:

  • soil shrinkage vertically,
  • load from the weight of the main structure,
  • the load from the roof with a rafter system, when it comes to utility or household buildings,
  • earth pressure load acting from the sides.

For insurance, the obtained load values ​​\u200b\u200bare increased by 2%.

professional planning

Plan strip support for a residential building requires more detailed calculations and professional execution. When performing calculations, the specialist takes into account the current provisions of SNiP and takes into account the slightest nuances, including operational loads, the possible weight of a snow cap on the roof, weight reduction when making window and door openings.

Schema Requirements

Plan the foundation of the tape type must meet the following requirements:

  • easy readability,
  • completeness of information on the main scheme,
  • the presence of additional information in applications,
  • sufficiency of data for construction without the need to perform additional calculations.

A detailed and complete drawing of any type of support structure is easy to implement. It eliminates the possibility of discrepancies and errors at the stage of preparatory work and installation.

Strip foundation sectional drawing with dimensions


In private and commercial housing construction, a strip foundation is often used, the drawing of which in a simplified form is a top view with linear dimensions.

Drawing and erection of a monolithic strip foundation

  • Preparatory work
  • Reinforcement of a monolithic foundation
  • Making mortar and pouring
  • Final stage

Who in the world does not know a monolithic strip reinforced concrete foundation? 8 out of 10 houses on the planet stand on this very foundation, because it is built quickly, is relatively inexpensive, and at the same time withstands quite serious physical and temperature stresses.

Drawing 1. Strip foundation made of monolithic concrete.

To build a strip foundation, the drawing must be made quite serious, but many can do without it.

Simplicity in manufacturing is ensured by the logic of the whole design.

Making a precast foundation is a little easier, but the system remains the same. For example, you can disassemble drawing 1, which is designed for brick one-story buildings located in the southern parts of the country (the small width of the foundation will not allow laying 2 bricks).

Preparatory work

You will need the following tools and materials:

Drawing 2. Reinforcement of the strip foundation.

  • shovel;
  • wheelbarrow for soil;
  • roulette;
  • gravel;
  • sand;
  • geotextile;
  • edged board;
  • wood saw;
  • hammer with nails;
  • ruberoid;
  • broken brick.

The first step is to mark the site on which all further activities will be carried out. The terrain plan indicates exactly where this should be done, and the drawing will tell you the exact parameters.

The width of the trench is 0.55 m, and the depth is 1.2 m. As the width increases, the strength capabilities also increase. If the strength of the foundation is sufficient, and the area of ​​\u200b\u200bsupport on the ground is insufficient, then an extension can be artificially made from below (drawing 2). If a depth of 1 m is not enough to go below the freezing layer, then you need to continue deepening, but usually this is enough.

Do not forget that the trench goes not only along the outer perimeter of the building, but also under all load-bearing walls. Sometimes there are no load-bearing walls in the house, but in this case a crosshair is made from below to increase the strength of the structure.

When digging a trench, you need to be careful enough, since in the end not only the vertical surfaces, but also the bottom should be even. If this is not the case, then the force of gravity will be distributed unevenly.

After the work of digging and leveling is completed, a layer of fine gravel for drainage is covered on the bottom, the thickness of which is 10 cm. Geotextile is laid on the gravel to separate it from what will happen from above.

Scheme of formwork strip foundation.

The next layer is laid out a 10 cm sand cushion, which is compacted with a vibrating plate or watered with water to shrink. Continuation of work is possible only after the sand has dried, i.e. after 2-3 days. Gravel and sand display drawing 3.

In the meantime, the sand dries, you can prepare the formwork. To do this, you will need to use a cutting board made of conifers (deciduous trees quickly rot from moisture), which is hammered together with nails into wooden shields. The shields themselves are installed in trenches and rise above the ground level by only 0.2 m. This height is quite enough for convenient operation of the house, and there will also be no overspending on the strip foundation.

Due to the fact that the thickness of 1 board is 3.5 cm, the width of each shield is 7 cm. As a result, only 41 + - 1 cm of usable space remains in the tunnel.

A roofing material is laid on the bottom and walls for waterproofing. After the formwork is removed, the roofing material will remain on the foundation.

Before you start reinforcing, you need to scatter broken bricks or plastic plates to the bottom. This will completely eliminate the contact of metal and moisture.

With constant exposure to moisture on the reinforcement system, the latter begins to rot.

Reinforcement of a monolithic foundation

  • reinforcing rod 12 mm;
  • hacksaw or grinder;
  • welding machine;
  • roulette.

Drawing 3. Sand cushion device.

This process is the most difficult from the technical point of view. Tying with wire in the standard way is not possible here, so you have to make a slight indulgence in quality and resort to welding. If desired, there is an option to use a harness at certain points, but mixing 2 options is inconvenient. Despite the standard drawing, it is better to slightly strengthen the structure, which will increase the margin of safety by at least half.

For reinforcing reinforced concrete bases, it is better to take a 12 mm rod, because. 10 will not give the desired strength indicators.

First of all, 12 parallel rods are laid in increments of 10 cm. The length of each of them is equal to the length of the base wall for which they will be used.

Perpendicular to these rods, another 1 layer is laid out in increments of 20 cm. The length of the perpendicular ones is 110 cm, which turns out to be exactly end-to-end joins the first. After laying the 2nd level, all places where the rods are in contact with each other must be welded using electric arc welding. It is advisable not to forget about 1 joint in order to achieve maximum quality.

After completing the crate, you need to make another one in the same way. At the second crate, even the joints will be located opposite, otherwise it will not be possible to complete the work. Between all parallel joints at 2 battens, segments of similar reinforcement are laid, but their length is 30 cm, after which each joint is securely tacked by the same welding.

After all the joints are made, you need to manually check each of them. Such reinforcement tunnels are made absolutely for each wall. Once all of them are prepared and installed in their places, you can proceed to the next stage of work.

Making mortar and pouring

Scheme of laying the strip foundation.

  • Concrete mortar m300 (water, cement, sand, gravel);
  • concrete mixer;
  • water;
  • polyethylene film.

To fill a monolithic strip foundation, automixers are usually ordered in order to meet the shortest possible time. Ideally, the timing should be limited to one light day, although it is very difficult to achieve such a performance. This will require not only automixers, but also hoses to deliver the solution directly to the site.

But this pleasure is expensive, besides, there is no guarantee that the supplier will provide exactly m300, and not m250, so most craftsmen in private construction prefer mixing on the spot. In practice, it takes much more time, but when a team of 8 people (2 concrete mixers) is working, the difference becomes illusory.

There is a lot of controversy on the topic of which cement to choose for concrete m300, because. it is easier to make it from m400, and m500 is 20% more economical. As a result, we will stop at m500, and the calculations will be carried out by volume in relation to 10 liters of dry cement.

Water is the main dilution material, which will require 6 liters. Only drinking water without impurities is used so that this does not affect the quality of concrete, and if there are a lot of impurities, then the solution will turn out to be completely fragile.

Sand is a fine dry aggregate. The larger its granules, the more the base material (cement) is saved, but the savings rarely reach 10%. In this case, 25 liters will be required. It is used exclusively in washed form.

Gravel (crushed stone) - its quantity in this case is 12 liters. Gravel particles never exceed a size of 7 cm, but they are never less than 0.5. It is he who allows you to save a lot when pouring, because. if you do without it (you will already get a solution of cement), then the price immediately rises by 30-35%. Apply only washed.

So, from 10 liters of cement, you can get 53 liters of high-quality m300 mortar. Sometimes, in order to save money, craftsmen increase the amount of coarse and fine aggregates, but this makes the final design of a monolithic strip foundation much weaker due to the level of fragility.

The solution is poured into the trench in layers of 15-20 cm. After pouring each layer, it must be plowed up to release the accumulated air. Such an action will significantly affect the quality of the reinforced concrete foundation.

After all the concrete is poured to the brim, the work is still not considered complete. The entire monolithic strip foundation, erected during the first 12-14 days, is watered. The reason for this is simple - when hardening, concrete absorbs moisture at a high rate, which is why it dries unevenly, and microcracks may appear.

But only at the slightest hint of precipitation, the solution is covered with plastic wrap, because. already at this stage, rain can begin to erode the reinforced concrete monolith. The time of complete solidification of the tape monolith is 28 days.

Final stage

After excavations have been carried out, the installation of forms, all kinds of protection measures, reinforcement and pouring of the strip foundation, then its full maintenance during hardening, we can assume that the foundation is ready.

In order to further secure it, you need to take additional precautions - storm water and a blind area are mandatory, but insulation and ring drainage are made as necessary on heaving soils or flooded areas. But it is better to take these precautions already when the house is built, because. at the same time it is impossible to do it physically.

Now the production of the tape base is completed completely, it remains to cover it with waterproofing, and you can start building a house.
