Rolled cloth "Bikrost" manufactured by "TekhnoNIKOL" is a modern material used in roofing. This product, due to its technical characteristics, significantly improves the quality of waterproofing and facilitates this time-consuming and dirty process. Practical experience of use shows that the product, along with the advantages, has disadvantages that the consumer needs to be aware of.
Structural composition
The main purpose of the material is to create an absolute tightness of the coating. Since we are talking about a roof, this means a high level of water resistance of the canvas. This applies to all types of building materials. The product has a two-layer structure and resembles a sandwich.
Synthetic polyester fiber or fiberglass, viscous bitumen mixture or bitumen modified with polymers, applied on both sides under high pressure, was taken as the basis. Three letters in the classification terminology of the material give information about the composition of the web.
The reinforcing (main) layer or the first letter can be indicated by the symbol:
- "X" (fiberglass);
- "C" or "T" (fiberglass);
- "E" (polyester fibers);
- "O" (cardboard backing).
Surface coverage information is indicated by the second letter:
- "K" (shale screening or granular rock);
- "P" (polymer film);
- "M" (mineral sand).
The third letter in the marking is the coating on the back of the material:
- "P" (polymer film);
- "M" (mineral mixture).
The material is produced in the form of a rolled web with a width of 1 m and a length of 7 to 15 m. The weight of the package also depends on the footage. It can be 30-45 kg. The fabric consumption during use is calculated taking into account the overlap (approximately 8 cm).
The material is in demand due to its wide application. It can be used when covering the roof, including its sloping options. Trademark products are suitable for use as a vapor barrier and waterproofing, suitable for restoration, renovation of roofs. The material has a relatively affordable price, which is consistent with the declared qualities of the material.
Characteristics
The parameters of the material and its distinctive properties are confirmed by certificates and other documentation that must be viewed when choosing a product. The product is applicable to different types of roofing. It can be used on straight and flat planes, there are several main characteristics.
It is worth noting the advantages of this material.
- Plasticity and flexibility. This indicator is important, because at low temperatures the web does not bend well and is prone to cracking. Brittleness is detected at -15 degrees (this applies to the HPP model).
- The material has good heat resistance parameters. These useful properties make it possible to avoid the spreading of the fabric from the reinforcing coating at high temperatures.
- Breaking strength. The reinforcing mesh can withstand up to 30 kg of tensile load, while the bitumen is not damaged.
- In addition, the material is water-absorbent. During the day, it absorbs water in an amount of 1% of its own mass.
- The high fire safety of "Bikrost" is due to its compliance with the flammability of B3. It belongs to the class of combustible materials G4.
- Ease of installation, installation in a short time. Installation can be done within a few hours.
- The main disadvantage is a short service life - about 5 years (with the exception of fiberglass-based material, which lasts from 7 to 10 years).
- Builders note that the material is quite heavy, and this is an undoubted shortcoming in the conditions of work on the roof.
- The workflow will require special construction tools and a gas burner, otherwise you can not hope for a quality result.
Features of different types
The two main types of Bikrost material have some differences. These are waterproofing sheets, most in demand for roofing.
- "Bikrost K"- products used for the top layer of the roof. Its outer surface is made of coarse shale or sand, the thickness of the material is 3.7 mm.
- "Bikrost P"- a distinctive characteristic of the product is a protective bottom layer in the form of a polymer film, the total thickness is 2.7 mm.
It is worth noting other varieties.
- CCI- frame fiberglass, obtained by weaving glass threads and impregnated with a mixture of bitumen. It is considered the most durable. Top and bottom has a protective polymer film. This coating can last up to 7 years.
- HPP used for the bottom laying of a multi-layer roofing carpet. The base of the material is fiberglass treated with a bituminous and polymer mixture, covered on all sides with polyethylene.
- HKP is based on fiberglass. From the outside, it has a slate topping. On the inside is a polymer. The canvas does not fade under the influence of the sun and is considered sufficiently durable due to the protection using granulate.
- TCH- refers to especially durable varieties, the basis is fiberglass. The upper side, in addition to bitumen, is covered with gray roofing granulate (shale grits). This type of soft roof is suitable for ballast and unloaded flat roofs. This is the most expensive product, the cost of which is determined by high quality and reliability.
- EKP- a plastic type of waterproofing sheet, successfully used for roofs with a slight slope.
- EPP- material suitable for thermal insulation, coated on both sides with a polymer film.
It is not necessary to do only one layer of waterproofing. With the help of two layers of "Bikrost" (HPP and HKP), superimposed one on top of the other, a higher quality of the coating is achieved, the service life is increased up to 12 years.
Installation of waterproofing
You can install waterproofing materials of this brand yourself. At the same time, it is desirable to have basic knowledge of the process and observe safety precautions. All work is carried out in special clothes and shoes.
For installation you will need:
- gas stove;
- propane tank;
- special roofing knife;
- bituminous primer;
- rolling roller with metal needles;
- hoses;
- hook;
- brush;
- roll cloth.
Preparation comes down to cleaning the surface from old coatings, small debris, moisture and dust. It is necessary to level the plane as much as possible. To do this, use a solution of cement or bituminous mastic.
After that, a primer mixed with gasoline is applied with a brush or brush. Its layer must dry before further work.
- The roll is rolled out at the place of fixation with a margin of 20 cm on both sides. The excess is cut off, the prepared sheet is folded again.
- The work should be done together. Rolling is done from the bottom to the top using a hook. At this time, the second worker warms up the material and the roof, trying not to destroy the bitumen layer.
- This is followed by the connection of the material with the base, after which they pass along the edges with a roller, paying special attention to the seams.
- After drying the lower part, they proceed to the front coating, using products with granulate to protect against external influences.
- With a roof slope of more than 15%, the soft roof is fixed along the edge of the eaves, less than 15% - fixed perpendicularly and in parallel.
It is impossible to walk on the coating until it is completely dry.
Roofing materials "Bikrost" are widely demanded products. The waterproofing fabric of this brand is especially popular. This is a relatively affordable material, the cost of which depends on the strength characteristics.

Bikrost is a universal bituminous waterproofing roll material designed for inexpensive roofing and waterproofing with a service life of up to 10 years. It is used at construction sites where there is no need to use expensive bitumen-polymer materials with a long service life.
Bikrost is available in two types:
- for the lower layer of the roofing carpet and for waterproofing works for various purposes (protection of the lower and upper surfaces of the roll - polyethylene film);
- for the top layer of the roofing carpet (protection of the lower surface of the roll - polyethylene film, the upper surface of the roll - coarse-grained dressing of various colors).
Knowing what the letters and numbers mean in the labeling of materials, you can quickly understand which one you need.
T, X and E- designation of the base on which the material is made - Tfiberglass, X-glass canvas, E-polyester;
To- designation of the upper protective layer of the roll - coarse dressing;
P- designation of the bottom protective layer of the roll - polyethylene film;
4,0
- a number indicating the weight of one square. meters of material (the larger the number, the thicker the material).
Bikrost stamps
When choosing a Bikrost brand, you need to know:
- for what types of work;
- what service life.
Based on the answers to these questions, it is much easier to make the right choice. Fiberglass-based bikrost are mainly used for waterproofing and roofing work on unloaded roofs with a small slope, which do not experience tensile and tensile loads during operation. Bikrost based on fiberglass can withstand high tensile loads, so it is used on loaded structures.
Scope and method of application of Bikrost
Bituminous rolled materials are used for waterproofing underground and surface structures for flat roofs up to exploited ones. In order for the waterproofing to be reliable and durable, it is necessary to qualitatively prepare the basis on which the rolled bitumen material will be laid in the future.
As a rule, a concrete screed serves as the basis, it must be dedusted and degreased with a bitumen primer, and then using a propane torch and other equipment, fuse the rolled material, not forgetting that the overlap between the sheets should be at least 10 centimeters. Thanks to the primer, the adhesion of the screed and the first layer of roofing or waterproofing will be the best. At objects where it is impossible to work with an open flame, bituminous adhesive mastics are used for gluing rolled bituminous materials.

Roofing "TechnoNIKOL Bikrost HPP" according to its price and technical characteristics can be attributed to economy class materials. The relatively low price of the "HPP" canvas, from 50 to 70 rubles per m 2, is successfully combined with the high mechanical characteristics of the canvas and the bitumen layer.
Operational characteristics of "TechnoNIKOL Bikrost HPP"
To select the optimal conditions for roofing work, you should pay attention to the main characteristics of the TechnoNIKOL HPP material:
Advice! Roofing "HPP", unlike the "HKP" series, does not have a protective surface layer of powder, so you should not unroll the roll or step on the panel, especially at low temperatures.
Practical use of waterproofing "TechnoNIKOL Bikrost HPP"
First of all, it should be noted that the material "HPP" is very rarely used on its own for arranging a soft roof. It can be used to overlap the walls and cornices in the area of the roof adjoining, aprons can be applied in the contact area with ventilation pipes, aerators and other elements installed on the roof. The thickness of 2.6 mm and the absence of an external powder make Bikrost KhPP an ideal material for the substrate under the main waterproofing layer from EKP or HKP.
If it is necessary to perform a single-layer waterproofing or soft roofing from HPP, experts recommend that the concrete base on which Bikrost will be laid be dried thoroughly, heated with a burner and treated with a TechnoNIKOL primer. Such a procedure helps to significantly improve the characteristics of adhesion to the base, especially if it is not possible to qualitatively remove moisture from a porous or cracked surface. Further, when surfacing the sheet, the primer will be compacted and fused with the bituminous layer of "Bikrost".
The material is sold in rolls, each weighing 45 kg. In one roll, a Bikrost canvas 15 m long and 1 m wide is rolled up. Warning information and information about the batch and release date must be applied on the outer surface of the roll.
When laying the roofing, the edge of the sheet is turned away from the roll, the edge and base are heated to operating temperature and the material is slowly rolled out in the required direction. The characteristics of the Bikrost bitumen sandwich allow heating up to only 80 ° C, at a higher temperature the bitumen will begin to flow and expose the fiberglass frame. In addition, in order to achieve high adhesion characteristics with the stone substrate, the heating must be carried out evenly, but quickly enough.
When arranging roofing coverings of a large area, it is more rational to lay several rolls at the same time. This allows you to get a dense coating with the best adhesive characteristics.
The “HKP” layer is laid after the revision of the quality of the laid “KHPP”, if necessary, the poorly adhering edge is lifted with a steel mounting, heated with a burner and pressed with a rag for 20-30 seconds.
Conclusion
The service life of even a single-layer roof from Bikrost TechnoNIKOL HPP is 7 years. A double layer of "HPP" and "HKP" allows you to get significantly higher performance, so such waterproofing can last 10-12 years, with a manufacturer's guarantee for "HKP" of 10 years. Single-layer coatings are more often used on temporary structures and in roof repairs.
