An integral part of the process of arranging the roof of any structure is its waterproofing. Moreover, the choice of one material or another directly depends on the type of roof. In this article we will talk about such a popular material as Bikrost - what it is, what its varieties are and technical characteristics. In addition, we will describe the sequence of work with this material and provide several recommendations.

"Bikrost" - what is it?

Bikrost roofing is one of the affordable varieties roll materials, which is of noticeably higher quality than, say, ordinary roofing felt. The main purpose of such a roof is to protect residential or industrial buildings from moisture and damage to the ceilings, load-bearing structures and other property. It is worth noting that bikrost is most preferable in the case of flat or slightly sloping roofs.

The following examples of the use of this material can be cited:

• arrangement of the upper or lower layers of the roof;
• ensuring waterproofing of load-bearing structures in large engineering structures - bridges, tunnels and others;
• replacing old ones roofing materials, whose service life has expired;
• installation on hard subfloors in areas that require additional waterproofing, such as basements or basement floors.

Bicrost roofing material consists of the following components:

• polymer film and a layer of fine gravel;
• oxidized modified bitumen layer;
• fiberglass - fabric or canvas;
• another layer of modified bitumen;
• a layer of polyethylene film to protect bicrost from sticking together during transportation and storage.

Among the main advantages of the material are the following capabilities:

1. The operating temperature range of the material is -30℃ to 50℃.
2. Bicrost can be laid at an air temperature of 0 ℃ (more details: " ").
3. The structure of the material ensures its high mechanical strength.
4. Provides high-quality insulation and waterproofing.
5. The service life of the material is at least 10 years.
6. Bikrost can be used to repair damaged roofing by laying it on top of the old coating. In addition, it can also be used as the main roofing material.
7. Installation is very quick and easy.
8. The material is accessible to most buyers due to its low cost and good quality.

Installation method

By and large, no special skills are required to work with bicrost. However, you will still have to acquire a certain set of tools and monitor compliance with certain standards.

In order to cover a roof with bicrost, you need to perform a certain list of works.

On initial stage should be done preliminary preparation roofs. The old, deteriorated waterproofing coating must be dismantled and the surface cleaned of dirt.

If the previously laid material is in good condition, it can serve as a basis for laying bicrost. However, it will need to be prepared for additional processing before further installation of new waterproofing.

The next step is the actual processing of the rough surface. IN in this case There are a number of subtleties. In particular, if cracks are found in the old coating and it has become permeable to moisture, it will need to be repaired. All the cracks are filled bitumen mastic, which is capable of plugging defects, returning the material to its original properties. Nevertheless, this method applicable only in cases where total area damage does not exceed 10% of the surface.

After the mastic has completely dried, the treated surface is covered with a layer of primer. It is needed for subsequent adhesion of bikrost with the old one. insulating material and preventing roof delamination.

Now you can get to work with bicrost. Since it is sold in rolls, it must be rolled out before installation. flat surface and leave for a while to straighten out. After this, the material is cut to the specified dimensions.

During the installation process, in order for the bikrost to adhere to the roof surface, it must be heated. For this you will need gas burner on propane or butane.

Start work from the edge of the roof. After heating the end of the roll with a gas burner, it is pressed to the surface. Next, the roll is gradually rolled out on the roof and warmed up. At the end, the laid bicrost is rolled with a heavy manual iron roller so that the material sets well.

As soon as the installation of the first roll is completed, you need to immediately take on the next one. Installation of each subsequent layer of bikrost is carried out with an overlap of 10-15 cm. Thus, complete tightness of the seams is achieved, and moisture does not enter the space between the rolls.

After installation, the tightness of the seams must be checked, since any pores and gaps will lead to a violation of the integrity of the coating.

1. Before starting work, the roof surface must be thoroughly cleaned of dirt and dust, and imperfections and defects in the rough coating must be eliminated.
2. Installation of bikrost must be done from the bottom up so that the water is gradually drained from the roof.
3. It is convenient to roll out and warm up rolled material using a hook without sharp edges.
4. To work at height, workers must be provided with safety belts.
5. Since operating gas burners can be hazardous to health, you should work in special clothing and a respirator.

Varieties of "Bikrost"

Manufacturers produce two types of bikrost - lining and roofing, therefore, they are marked with the letters “P” and “K”.

For installation, Bikrost P is used as a waterproofing intermediate layer. It has double sided bitumen base, and is covered with a fusible film on top.

But “Bikrost K” serves as a finishing waterproofing material for roofing. The lower part of such a coating consists of bitumen, and on top there are small and coarse-grained granite chips.

Explanation of symbols

There are a number of varieties of Bikrost roll material, therefore, to determine its composition, it is marked with a three-digit letter code.

Here is a breakdown of the letter designations:

1. P – presence of polymer film.
2. K – coarse gravel chips.
3. M – mineral powder with a fine fraction.
4. C – the material is based on standard fiberglass.
5. T – frame fiberglass is used.
6. X – the base is made of fiberglass.
7. E – polyester non-woven fabric at the base of the material.
8. O – the basis is specialized cardboard.

The brands KhPP, TKP, HKP, TPP are in greatest demand; EKP Bicrost and other products are also of very high quality, although they are purchased somewhat less frequently. In addition to the composition, the marking indicates such characteristics of bikrost as weight in kg/m2, as well as the color of mineral chips and specifications used in production. Note that the thickness of the bicrost will also depend on the component composition, which it is advisable to take into account when carrying out work.

Material Specifications

The technical characteristics of bikrost may differ slightly depending on the brand of product, since their component composition is also different.

Let's consider the main parameters of various grades of material:

• Bikrost HPP- This is a material used primarily as lining waterproofing. It is based on fiberglass, on which a layer of bitumen is applied on both sides. Upper part roll material cover protective film, which prevents layers from sticking together. The characteristics of bicrost HPP do not allow its use for any other purposes, since it does not have high mechanical strength.
• Bicrost brand HKP is more durable, so this material is used as the main roof. In this case, the base is also fiberglass. On the front side, a layer of coarse mineral chips is applied to the base, and below is a layer of oxidized bitumen. The rolled material is protected from sticking by a low-melting film.
• TCH- This is a type of bikrost, which is based on fiberglass. The front part of the material is covered with a mixture of bitumen and gravel, and the back part consists of a bitumen layer. This bicrost has good mechanical strength and is mainly used for inversion roofs.
• Bikrost Chamber of Commerce and Industry It basically contains frame fiberglass, which is covered with bitumen layers on both sides. That's why this type material is used to perform lining waterproofing. This variety of bikrost performs well in combination with the HKP and TKP brands.
• Bikrost SPP- This is the cheapest type of roll waterproofing. It consists of a main layer of standard fiberglass, which is covered with a mixture of bitumen with fine granite granules on one side and oxidized bitumen on the other.

Storage conditions

Please note that bicrost roll wrappers tend to stick together. Therefore, you only need to store it in a vertical position, without stacking several rolls on top of each other. If stored incorrectly, even protective films cannot prevent sticking.

In addition, bicrost should only be stored in indoors, without direct access sun rays and precipitation, at a temperature not lower than -10 ℃.

Results

Thus, thanks to the variety of bicrost types, everyone can choose for themselves best option and enjoy a well-functioning, protected roof for many years. At the same time, installation will not take much effort and time.

Bikrost is a universal bitumen waterproofing roll material designed for inexpensive roofing and waterproofing with a service life of up to 10 years. It is used on 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 bottom layer of roofing carpet and for waterproofing work for various purposes(protection of the bottom and top surfaces of the roll - polyethylene film);
• for the top layer of roofing carpet (protection of the lower surface of the roll is polyethylene film, the upper surface of the roll is protected by coarse coating of various colors).

Knowing what the letters and numbers in the labeling of materials mean, you can quickly understand which one you need.

T, X and E- designation of the base on which the material is made - T-fiberglass, X-fiberglass, E-polyester;
TO- designation of the upper protective layer of the roll - coarse-grained topping;
P- designation of the bottom protective layer of the roll - polyethylene film;
4,0 - a number indicating the weight of one square meter. meter of material (the larger the number, the thicker the material).

Bikrost brands

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 do right choice. Bikrost based on fiberglass are used mainly for waterproofing and roofing works on non-load-bearing roofs with a low slope, which during operation do not experience tensile or tensile loads. Bikrost based on fiberglass can withstand high tensile loads, therefore it is used on loaded structures.

Area and method of application of Bikrost

Bitumen roll materials are used for waterproofing underground and above-ground structures for installation flat roofs up to the exploited. In order for the waterproofing to be reliable and durable, it is necessary to qualitatively prepare the base on which the rolled bitumen material will be laid in the future.

As a rule, the basis is concrete screed, it must be dedusted and degreased using a bitumen primer, and then the rolled material must be fused using a propane torch and other equipment, not forgetting that the overlap between the panels 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 sites where it is impossible to work with an open flame, for gluing rolled bituminous materials bitumen adhesive mastics are used.

Description of material

Bikrost is a waterproofing sheet consisting of a durable base onto which a mixture of bitumen binder and fillers is applied. The material is intended for installation and repair of roofing carpet.

Bikrost K is used to install the top layer of roofing carpet. Coarse-grained topping on the front side protects the material from exposure to sunlight.

Bikrost P is used as a vapor barrier when installing a roofing carpet (the bottom layer of the system). Fine-grained powder or film can be used as a protective layer of the material.

Bikrost material can be used in all climatic regions (according to SNiP 23-01-99*).

Scope of application:

Designed for waterproofing buildings, structures and building structures.

Structure:

Bikrost is produced by double-sided application of a bitumen binder consisting of bitumen and filler to a fiberglass (fiberglass, perforated fiberglass, frame fiberglass) or polyester base, followed by application to both sides of the canvas protective layers. Coarse-grained (shale, asbagal), fine-grained (sand) coatings and polymer film are used as protective layers.

Brands:

Depending on the type of protective layers and area of ​​application, Bikrost is produced in two brands:

Bikrost K— with coarse-grained topping on the front side and polymer film on the underside of the canvas; used to install the top layer of waterproofing with sun protection;

Bikrost P— with fine-grained topping or polymer film on the front side and polymer film on the bottom side of the canvas or fine-grained topping on both sides of the canvas; applies to device lower layers waterproofing.

Work execution:

According to the “Guidelines for the design and installation of roofs made of bituminous materials from the roofing company TechnoNIKOL”, it can be used in all climatic regions according to SNiP 23-01.

Rolled fabric "Bikrost" manufactured by "TechnoNIKOL" - modern material, used in roofing work. This product due to its technical characteristics, it significantly improves the quality of waterproofing and facilitates this labor-intensive and dirty process. Practical experience of use shows that, along with advantages, the product has disadvantages that the consumer needs to be aware of.

Structural composition

The main purpose of the material is to create absolute tightness of the coating. Since we're talking about about the roof, this means high level water resistance of the fabric. This applies to all types of building materials. The product has a two-layer structure and resembles a sandwich.

The base is synthetic polyester fiber or fiberglass, a viscous bitumen mixture or polymer-modified bitumen, applied on both sides under high pressure. Three letters in the classification terminology of the material provide information about the composition of the fabric.

The reinforcing (base) layer or the first letter can be indicated by the symbol:

• “X” (fiberglass);
• “C” or “T” (fiberglass);
• "E" (polyester fibers);
• "O" (cardboard backing).

Information about surface coverage is indicated by the second letter:

• “K” (shale screenings or granular rock);
• “P” (polymer film);
• "M" (mineral sand).

The third letter in the marking is the coating on the reverse side of the material:

• “P” (polymer film);
• "M" (mineral mixture).

The material is produced in the form of a roll 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 consumption of the canvas 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 to cover the roof, including its inclined variants. The brand's products are suitable for use as vapor barriers and waterproofing, and are suitable for restoration and renovation of roofs. The material has a relatively affordable price, which fully corresponds to the declared qualities of the material.

Characteristics

Material parameters and its distinctive properties confirmed by certificates and other documentation that must be viewed when choosing a product. The product is applicable for different types roofs. It can be used on straight and level 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 fabric bends poorly and is susceptible to cracking. Fragility is detected at -15 degrees (this applies to the HPP model).
• The material has good heat resistance parameters. These beneficial properties make it possible to avoid spreading of the fabric from the reinforcing coating when high temperature.
• Tensile strength. The reinforcing mesh can withstand up to 30 kg of tensile load without damaging the bitumen.

• In addition, the material is characterized by water absorption. During the day, it absorbs water in the amount of 1% of its own weight.
• The high fire safety of Bikrost is due to its compliance with flammability B3. It belongs to the class of flammable materials G4.
• Easy installation, installation in short terms. Installation can be completed within a few hours.

• The main disadvantage is the 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 drawback in terms of roofing work.
• The work process will require special construction tools and a gas burner, otherwise you can’t hope for a high-quality result.

Features of different types

The two main types of Bikrost material have some differences. These are waterproofing sheets that are most in demand for roofing work.

• "Bikrost K"– products used for the top layer of roofing. Its outer surface is made of coarse shale or sand, the thickness of the material is 3.7 mm.
• "Bikrost P" – distinctive characteristic The product has a protective bottom layer in the form of a polymer film, the total thickness is 2.7 mm.

It is worth noting other varieties.

• Chamber of Commerce and Industry– frame fiberglass fabric obtained by weaving glass threads and impregnated with a mixture of bitumen. It is considered the most durable. It has a protective polymer film on top and bottom. This coating can last up to 7 years.
• HPP used for the bottom laying of a multi-layer roofing carpet. The base material is fiberglass treated with bitumen and polymer mixture, covered on all sides with polyethylene.
• HKP It is based on fiberglass. WITH outside it has a slate topping. There is a polymer on the inside. The canvas does not fade when exposed to the sun and is considered quite durable due to protection using granulate.

• TCH– refers to particularly durable varieties, the base is fiberglass. In addition to bitumen, the upper side is covered with gray roofing granulate (shale grains). This type of soft roof is suitable for ballast and non-loaded flat roof. This is the most expensive product, the cost of which is determined by its high quality and reliability.
• ECP- a plastic type of waterproofing sheet, successfully used for roofs with a slight slope.
• EPP– a material suitable for thermal insulation, covered on both sides with a polymer film.

It is not at all necessary to do only one layer of waterproofing. With the help of two layers of "Bikrost" (HPP and HKP), superimposed on one another, more high quality coating, service life increases to 12 years.

Installation of waterproofing

Stow waterproofing materials this brand you can do it yourself. It is advisable to have basic knowledge of the process and follow safety precautions. All work is carried out in special clothing and shoes.

For installation you will need:

• gas burner;
• propane tank;
• special roofing knife;
• bitumen primer;
• rolling roller with metal needles;
• hoses;
• hook;
• brush;
• rolled fabric.

Preparation comes down to cleaning the surface of 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 bitumen mastic.

Afterwards, 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 and the prepared sheet is folded again.
• The work should be done by two people. Rolling is done from bottom to top using a hook. At this time, the second worker warms up the material and the roof, trying not to destroy the bitumen layer.
• Next comes the connection of the material to the base, after which they pass along the edges with a roller, paying special attention to the seams.
• After the bottom part has dried, they begin the front coating, using products with granulate to protect against external influences.
• When the roof slope is more than 15% soft roof fixed along the edge of the cornice, less than 15% - fixed perpendicularly and parallel.

You cannot 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. It's comparative available material, the cost of which depends on the strength characteristics.

To learn how to cover a garage roof with TechnoNIKOL with your own hands, watch the following video.

From time immemorial, waterproofing work has been considered hard and dirty work; craftsmen had to work with a large number of liquid tar, bitumen, inhale soot and fumes from tar combustion products. With the advent of rolled roofing materials, such as Bikrost TechnoNIKOL, work has not only become cleaner, the quality and technical characteristics of the waterproofing layer have improved by an order of magnitude.

What materials are used for laying soft roofing?

Among several dozen varieties of rolled materials for waterproofing from the Technonikol company, there is plenty to choose from, but the dry characteristics and descriptions in the product catalog give a vague idea of ​​​​the advantages and disadvantages of the Bikrost soft roof.

Today there is considerable practical experience in the use of Technikol products, on the basis of which we can recommend proven best side a couple of typical waterproofing coatings, widely used for roofing work:

• "TechnoNIKOL Bikrost HKP" — roll waterproofing with a protective surface layer of shale grit or granulated sand;
• "TechnoNIKOL Bikrost HPP"- almost identical in structure to the previous coating, but instead of protective powder, a protective polymer film is glued to the “HPP”.

Both waterproofing options are made on the basis of perforated fiberglass, with a double-sided layer of bitumen rolled onto the base, oxidized and modified to increase viscosity with rubber-like fillers.

Important! The vast majority of Bikrost coatings, including HKP and KhPP, are designed for use in all climatic zones of Russia.

Use and technical characteristics of "Bikrost HPP"

Roofing covering "TechnoNIKOL Bikrost HPP" in its price and technical characteristics can be classified as economy class materials. The relatively low price of the KhPP canvas, from 50 to 70 rubles per m 2, is successfully combined with high mechanical characteristics canvas and bitumen layer.

Operating 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:

1. The control sample of the Bikrost HPP fabric can withstand a load of at least 30 kg in the transverse direction without violating the integrity of the reinforcing tape and the bitumen layer;
2. High temperatures and performance characteristics roofing sheet "KhPP" allow you to avoid deformation, spreading, cracking or delamination of the material. The “KhPP” sample exhibits the fragility of the bitumen layer at temperatures below 15 o C. At 0 o the sheet can still be bent on a blank with a diameter of 25 mm without much effort;
3. The insulating layer "Bikrost TechnoNIKOL HPP" shows good characteristics resistance to water absorption and water permeability. In 24 hours, the sample, completely immersed in water, managed to absorb moisture of no more than 1% of its own weight.

Advice! The “KhPP” roofing covering, unlike the “HKP” series, does not have a protective surface layer of powder, so you should not unnecessarily roll out the roll or step on the sheet, especially at low temperatures.

Practical use of TechnoNIKOL Bikrost HPP waterproofing

First of all, it should be noted that the KhPP material is very rarely used independently for the construction of soft roofs. It can be used to overlap walls and cornices in the area where the roof abuts, and 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 external powder make “Bikrost HPP” ideal material for the substrate under the main layer of waterproofing from “EKP” or “KhKP”.

If it is necessary to perform single-layer waterproofing or soft roofing from CPP, experts recommend concrete base, on which the Bikrost will be laid, dry thoroughly, heat it with a burner and treat it with a primer from TechnoNIKOL. This procedure helps to significantly improve the adhesion characteristics to the base, especially if it is not possible to efficiently remove moisture from a porous or cracked surface. Further, when surfacing the fabric, the primer will compact and fuse with the Bikrost bitumen layer.

The material is sold in rolls, weighing 45 kg each. One roll contains Bikrosta fabric 15 m long and 1 m wide. Warning information and information about the batch and production date must be placed on the outer surface of the roll.

When laying the roofing covering, the edge of the sheet is turned away from the roll, the edge and base are heated to operating temperature and slowly roll out the material in the required direction. The characteristics of the Bikrosta bitumen sandwich allow heating to only 80 o C; at a higher temperature, the bitumen will begin to flow and expose the fiberglass frame. In addition, in order to ensure high adhesion characteristics to the stone base, heating must be carried out evenly but quickly enough.

When installing roofing coverings over a large area, it is more rational to install several rolls at the same time. This allows you to obtain a dense coating with the best adhesion characteristics.
