Bicrost roll material. Bikrost hkp, roll roofing. Prices for various types of gas burners and blowtorches

Recently, the construction industry has been offering developers a huge selection of different rolled roofing materials. If not so long ago only natural bitumen and cardboard-based roofing felt were used for these purposes, today not even all professional builders know by heart the existing names of rolled materials and their properties. This, on the one hand, significantly improves the quality of roofing coverings, and on the other hand, makes the choice much more difficult for inexperienced consumers. Moreover, not a single company indicates the shortcomings of its products; the emphasis is always placed only on the positive properties. In order to better understand what bikrost is, you need to learn a little about the general requirements and properties of all types of soft roofing coverings.

This type of coating is used mainly on flat roofs with a slope of up to 12°. But in villages you can find options for roofing and gable roofs, most often these are old country houses or various outbuildings.

Bikrost is manufactured by the very famous TechnoNIKOL corporation, and its specialists pay great attention to the quality of their products. This takes into account not only the current requirements for soft surfaces, but also developments for the future. The roof is manufactured on the most modern equipment using innovative technologies and materials. Each batch undergoes visual technical control, and laboratory tests are carried out using a random method.

The TechnoNIKOL company produces many types of rolled roof coverings

All types of bicrost meet basic operational requirements.

Due to the fact that bikrost can be used both for the internal lining layer and for the finishing coating, the structure of both types of roofing material is somewhat different.

1. Base. For these purposes, fiberglass fabric (material that is very durable in terms of physical parameters), polyester fiber (performance is somewhat worse) or fiberglass (mechanical performance is much lower) is used. All bases are not afraid of moisture.

   

2. Bitumen impregnation. It is available on both sides of the roll, and special innovative additives are added to increase resistance to UV rays, ductility at sub-zero temperatures and maintaining characteristics after heating to +80°C.

   

3. Protective polyethylene film. Purpose – to prevent rolls from sticking together during transportation and storage. The bicrost lining has such a film on both sides, the finishing film is only on the reverse.

   

4. Topping made of mineral or natural stone. Available only on rolls for finishing on the front side. Purpose – protection of bitumen from hard ultraviolet radiation and improvement of design characteristics.

   

Technical characteristics and types of material

Depending on the purpose, each type of material has its own marking.

Table. Bicrost brands

Recommendations for use in regions, depending on operating temperature conditions, are prescribed in SNiP 23-01. In terms of flammability, bikrost belongs to group G4, in terms of the speed of fire spread to RP4, and in terms of ignition temperature - B3. These characteristics indicate that it is considered a fire hazardous material; work requires compliance with all safety precautions.

Step-by-step instructions for laying bicrost

First, let's look at an interesting option for using a car gas equipment to connect a gas burner. Currently, many motorists have begun to abandon gasoline engines due to the constant increase in fuel prices. LPG is not uncommon; car enthusiasts have switched their cars to this cheap and environmentally friendly fuel. Such equipment makes it possible to connect the burner directly to it, there is no need to borrow or buy a gas cylinder.

Burner connection method

How is the connection made?

Step 1. Park the car as close as possible to the garage or other building that you plan to cover with bicrost.

Step 2. Open the hood and remove the plug from the gas supply unit. It is located above the cylinder head, has a rectangular shape, and is most often blue. An important distinguishing feature is that rubber hoses extend from this device to each engine cylinder. The plug is located on the side and is made of plastic. It is removed from the technological socket with medium force after the retaining lock is released. Pull it towards you and release the hole.

Step 3. Place the adapter on the free pipe. This is an ordinary hose of suitable diameter. To ensure tightness, tighten it with a clamp.

Step 4. Insert a piece of metal tube into the other end of the rubber adapter and also tighten the connection with a clamp, attach the burner hose. Start the engine and you can start fusing the rolled roofing.

Such actions take only a few minutes and save time. There is no need to lose it looking for a gas cylinder, check its serviceability and warranty period, or visit a special gas station. All that remains is to lift the materials and tools onto the roof and begin the work.

Laying bicrost

For high-quality installation of roll coverings, a flat, clean and durable base is required. If you have an old, worn-out coating with numerous damages, it is better to completely dismantle it or at least remove the most damaged areas.

If the building has been in use for a long time and a major renovation of the structure is planned in the coming years, one layer of bicrost will be sufficient to temporarily protect the roof from precipitation. It is this example using cheap coating that we will consider. In all other cases, laying must be carried out in at least two layers with the obligatory overlap of the overlaps of the lower panels.

Step 1. Thoroughly clean the surface of the ceiling from various debris, vegetation and dirt. Trim the ridges. Fill deep cracks and holes with a cement-sand mixture. Take all measures to ensure that cheap bicrost with a weak base does not suffer mechanical damage.

Step 2. If there was an old soft roof on the roof, then you need to inspect it for the presence of swelling and peeling. Such places are opened and separately melted; you can cut small pieces from the new roll and cover the surface. But in most cases, repairs are completed without patches, and leaks do not appear due to swelling. They must be straightened so that the new coating does not stretch or become damaged. These are preventive measures of the same type as leveling the concrete base.

Step 3. All vertical connections must be glued in at least two layers, regardless of their number on a horizontal roof. The fact is that in these places there are maximum displacements of architectural elements, which significantly increases the risk of leaks.

Step 4. Proceed with laying bicrost on a horizontal surface. If the installation is carried out not on the old coating, but on a screed, the surface is first primed with liquid bitumen. Roll out the rolls only towards yourself, try not to walk on the hot soft surface. We have already said that the cheapest bicrost with a fiberglass base is used. The word canvas itself does not mean that it is the durable tarpaulin fabric familiar to many consumers. In fact, it does not have threads; it is not made on looms, but by pressing thin fibers. This coating is characterized by minimal strength and requires very careful handling.

Practical advice. The burner should heat not only the bikrost, but also the roof. Due to this technology, the adhesion of the coating to the base significantly increases, it does not matter whether it is a concrete slab or old bitumen.

You need to heat the back side of the roll; there is a special plastic film on it. It should not burn, and the bitumen should not boil or bubble. Do not allow overheating; if burns appear on the front side, then this is a defect; after fusing the materials, you will have to install patches on them. At the optimal heating temperature, the film becomes transparent, it completely melts, and the bitumen softens greatly, but does not boil or burn.

To facilitate the process and increase the safety of the work, roll out the roll with any available device, you can bend ordinary wire. Work only in dry weather with positive air temperatures.

Step 5. The second roll must be rolled out so that its edge lies exactly on a special edge without stone chips. If the installation process is correct, then molten bitumen should protrude along the entire overlap line.

Step 6. Once the entire flat part of the roof is covered, carefully finish the junctions. It should be remembered that it is better to seal all the most dangerous places with two layers.

Important. Rolled bicrost has bitumen impregnation on both sides. The bottom one must melt; it performs two tasks: it tightly connects the coating to the base and does not allow water to pass through. The top impregnation only seals the roof.

Bicrost trimmings left after laying the roof should not be thrown away. If a defect was made during the work, and swelling, peeling or depressions appeared on the coating, using these pieces it will be possible to eliminate the defects by applying neat patches.

And universal advice - never rush, built-up roofs react very negatively to any deviations from the recommended installation conditions.

Video - Bikrost: what is it

You have learned the technical parameters and operational characteristics of Bikrost. But this is not the only roofing material produced by TechnoNIKOL. It produces a wide range of coatings of excellent quality. To make the right choice, you need to know their capabilities; you can read about brief characteristics at.

Regardless of the type of roof, all roofs need high-quality waterproofing. Agree that it is better to spend money on waterproofing once than to experience discomfort all your life due to rainwater getting inside your home. Because of this phenomenon, home owners will not only feel discomfort, but also endanger the health and life of their family. Since due to a constantly damp ceiling, fungus or mold can form on its surface and on the surface of the walls.

Depending on the roof structure, roofing materials must be selected with characteristics that are perfect for this design. For roofing repair work on a flat roof, one of the best materials is Bikrost TKP.

Description

“Bikrost TKP” is an economical waterproofing, which is made by applying a special adhesive composition, which is based on oxidized bitumen, on the surface of a rot-resistant rolled material such as fiberglass or fiberglass.

When purchasing this material, the waterproofing kit includes a special hook that is used to unroll the rolls.

Nowadays, “Bikrost TKP” is made from two types of coating:

1. Coarse powder. As a rule, it is used for the top roofing layer of the carpet. For the top layer of topping, use regular sand, asbestos and shale.
2. Polymer film. Used for surface waterproofing or as a base layer for roofing carpet.

Manufacturers of this material have taken care of its fairly wide variety. That is why the material is often used not only for waterproofing ordinary houses, but also for waterproofing complex structures such as tunnels and bridges. Fusing "Bikrost TKP" is carried out using a blowtorch, gas torch, or using a powerful hair dryer. In some cases, the “Bikrost TKP” is attached to a pre-applied mastic, which is based on many polymers.

For restorative repairs, the composition can be applied in just one layer; during major repairs, it is recommended to apply two layers. Waterproofing can be done not only in places where almost no one can see it, but also in areas that are visible to other areas. Because manufacturers were able to improve this material, making it more attractive.

By following the tips listed above, waterproofing can last up to ten years.

Marking and designation of roofing materials

Each roll has a specific set of letters. Each of the letters written on the material implies the presence of certain elements, for example:

1. “K” – coarse-grained powder.
2. “P” – polymer film.
3. “T” – frame fiberglass.
4. “C” – fiberglass base.
5. “X” – fiberglass base.
6. “O” – the base includes specialized cardboard.
7. “E” – the material is based on polyester non-woven fabric.

Specifications

The marking must also indicate the color of the topping, weight and compliance with specifications.

Storage

It may seem that the method of storing this material is not particularly important, because it does not absorb moisture and will not suffer much if several heavy objects are placed on it. However, this is not entirely true, since there is an entire technology dedicated to the storage and transportation of these components.

It takes a day for the waterproofing to completely dry after its manufacture, which is why transportation is not carried out immediately from production. During transportation, Bikrost is installed in a vertical position on pallets or on specially equipped containers. If the material is stored in open air, its storage should not exceed two weeks. It is not recommended to stack waterproofing on top of each other; placing two pallets with evenly distributed weight is acceptable.

TechnoNIKOL waterproofing is modern, reliable materials that, if installed correctly, will last for many years. By following the tips from this article, you can get the job done quickly and efficiently. Therefore, be careful both in the choice of material and in its installation.

BICROST TCH

gray granulate

Weldable waterproofing material. Flexibility on timber R=25 mm, not higher than 0°C, heat resistance + 80°C. Base: fiberglass

Technical characteristics of waterproofing Bikrost TKP gray granulate:

Purpose, scope of waterproofing Bikrost TKP gray granulate

Bikrost HKP gray granulate is used to organize the roofing of various structures and buildings. It is characterized by exceptional strength, reliability and durability. Bikrost HKP gray granulate is ideal for installing roofs that will be subject to intense loads and mechanical stress in the future.

In addition, this roofing material, like other bituminous materials, has a very attractive appearance, so a building with a roof where the waterproofing material Bikrost TKP gray granulate was used will stand out from the crowd. This material is used to construct the top layer of roofing carpet. In order to achieve the most effective and long service life, it is better to use Bikrost TPP gray granulate as a base level under the roofing Bikrost TKP. This type of device will help optimize the waterproofing properties of the material, extend the service life, and also ensure that the roof exposed to loads remains reliable and durable.

Structure and properties of waterproofing Bikrost TKP gray granulate

Bikrost TKP gray granulate is produced by the method of double-sided fusion onto a fiberglass or polyester base of bitumen binder, coated on both sides with protective layers, which are presented in the form of coarse-grained (asbagal, shale), fine-grained (sand) toppings and polymer film. The fiberglass base can have several varieties - frame fiberglass, fiberglass or perforated fiberglass. Due to the presence of a fiberglass base, the waterproofing material Bikrost TKP gray granulate has high strength, and durability, long service life and frost resistance are explained by the presence of a specific filler in the bitumen composition. The protective film covering the lower surface of the material sheet prevents sticking when stored in rolls, and the mineral coating provides reliable protection from ultraviolet rays.

Tips for installing waterproofing Bikrost TKP gray granulate

The waterproofing material Bikrost TKP gray granulate is laid by fusing using a propane torch. This installation method is more economical and effective compared to laying roofing felt, since fusing instead of gluing significantly reduces the layering of the waterproof fabric. Laying works of waterproofing Bikrost TKP granulate gray is carried out at an air temperature not lower than -15°C. Laying is carried out only on the lining layer, which must completely cover the entire surface of the base. The waterproofing material is rolled out to form overlaps (8-10 cm), which are the location of the seam.

Additional information about waterproofing Bikrost TKP gray granulate

The waterproofing material Bikrost TKP gray granulate combines the optimal combination of low price and good quality. It is guaranteed to last 10 years without replacement or major repairs, both for roofing and waterproofing. The material Bikrost TKP gray granulate goes on sale in two versions depending on the type of protective coating: P - used for the installation of the bottom layer of roofing sheets and waterproofing coatings. On the front side it is covered with fine-grained mineral coating or polymer film, on the bottom side with polymer film, or on both sides with fine-grained coating. K - used for the installation of the top layer of the roof and is covered on the front side with coarse-grained topping, with a lower polymer film.

Bikrost: characteristics and application features

Classic bitumen roofing felt, which was traditionally used for waterproofing roofs and external roofing coverings, has been practically forced out of the market by modern materials based on modified bitumen. These include the Bikrost roll material, which allows you to install a reliable waterproofing cake on a flat roof and roof with a low slope. Laying method - fusing.

Features of the material

Despite the fact that the affordable Bikrost is an economical option, it allows you to ensure high quality waterproofing of roofs or other building structures. Depending on the type of material, it can be used as an underlay or top layer of a bitumen roofing cake.

The basis of Bikrost is a material made of glass or polyester fiber. A layer of modified bitumen with filler is applied to the base on both sides - it is the bitumen that is responsible for water and vapor resistance. The material differs from roofing felt in the increased amount of bitumen and binder.

The outer layer of the bitumen sheet, intended for installation of the lining carpet, is a polymer film or fine-grained topping. Bikrost for the external covering of the roof is supplied with an outer protective layer of coarse-grained mineral chips.

Bikrost structure

Shale coating protects the bitumen layer from mechanical damage and destruction under the influence of ultraviolet radiation. Modified bitumen is resistant to cracking at low temperatures, which extends the life of the roof deck.

Application

Bikrost, the top layer of which is a coarse or fine-grained coating, is designed for use as a finishing layer of roofing carpet on a flat roof or a roof with a low slope. The material successfully resists atmospheric influences and mechanical loads. But in regions with increased solar activity in hot weather, the canvas softens and can be damaged under high point mechanical loads.

Canvas with protective coatings made of polymer film are used as waterproofing and vapor barrier. During the installation process, the bottom layer melts, which ensures a tight fit and high adhesion of the elastic material to the prepared base. The absence of coarse-grained topping in Bikrost, intended for arranging underlay carpet, contributes to high-quality adhesion of the top layer of the roofing cake to the bottom.

Bikrost with a film coating is suitable for waterproofing walls and floors, foundations, basements, ceilings between floors, and for creating vapor-tight barriers. This material can be used to insulate water pipes, tunnels and other structures.

To fuse the sheets, professionals use a propane torch; for self-assembly, they use a technical hair dryer or a blowtorch. In some cases, installation using bitumen mastic is allowed.

Fusing of Bikrost fabric

Bikrost is a modern built-up roofing material that is suitable for restoration (can be installed in one layer on an old waterproofing pie), for reconstruction or arrangement of a roof covering with a rigid base.

Types of Bicrost

The Bikrost marking indicates the type of base and types of protective layers (top and bottom, respectively). The purpose of the material and the scope of its use depend on this.

The base made of frame fiberglass is designated by the letter “T”, from fiberglass - “X”, from polyester fiber - “E”. Frame fiberglass, compared to fiberglass, has higher strength, including tensile strength. Fabrics based on fiberglass and polyester are used for use under light load conditions.

Bikrost is produced in two grades - for the top layer of the roof (with coarse-grained coating) and for the lining (with a protective layer of film on both sides). The letter “K” denotes coarse-grained granulate or slate dressing, “P” - a protective polymer film that protects the rolled material from sticking during storage.

TechnoNIKOL Bikrost HPP 1x15m is a budget material based on fiberglass, suitable for installing underlayment on unused roofs, for waterproofing walls and floors in rooms, and horizontal surfaces of foundations.

Bikrost EPP has a higher tensile strength, the scope of use is the same as that of rolled bitumen sheets marked HPP.

TechnoNIKOL Bikrost TPP 1x15m - due to the base made of frame fiberglass, it is suitable for installing the lining layer of load-bearing coatings, can be used to protect horizontal and vertical surfaces of foundations from moisture, and can be mounted on roofs with a large slope.

Bikrost TKP is an affordable material for laying the finishing layer of roofing pie. Also suitable for waterproofing various building structures.

Bikrost EKP is more durable and elastic, suitable for installation on sloped roofs, and successfully withstands operational loads.

Bikrost HKP is a roofing material designed for operation under high loads. Suitable for pitched roofs, for waterproofing vertical surfaces of structures.

Specifications

Bikrost has good performance properties:

• 100% steam and waterproof;
• maintaining elasticity at low temperatures;
• resistance to deformation when heated to +80°C.

The strength of the material depends on the type of base:

• for fiberglass – 300 N;
• for polyester fiber – 350 N;
• for frame fiberglass – 600 N.

The service life for HPP and HKP is 5 years, for EPP and EKP - 7 years, for TPP and TKP - up to 10 years.

Taking into account the strength parameter and other characteristics, Bikrost is superior to roofing felt, while remaining in the niche of the most affordable materials, unlike many other rolled bitumen coatings. According to SNiP 23-01, the material is suitable for use in any climatic regions.

Table. Technical characteristics of Bikrost

Dimensions and weight

The standard width of the roll material is 1 meter. The length can be 10 meters (for Bikrost with a top coating of crumbs) or 15 meters (for material with a top coating in the form of a film). When calculating how much material is required to arrange the roofing pie, it should be taken into account that the installation of the strips is carried out with an overlap of about 10 cm.

• HPP, EPP, TPP – 2.7 mm;
• HKP, EKP, TKP – 3.7 mm.

The weight of 1 m² of film-coated canvas is 3 kg, the weight of 1 m2 of crumb-coated cloth is 4 kg. Respectively, The weight of the roll, taking into account the length, is:

• 45 kg for CCI, EPP and HPP;
• 60 kg for TKP, EKP and HKP.

Bikrost is a fire hazard class 5 material, it is:

• highly flammable (group B3 according to GOST 30402-96);
• highly flammable (group G4, according to GOST 30244-94);
• strongly spreading flame (group RP3, according to GOST R 51032-97).

The production of Bikrost material is regulated by GOST 12.1.005-88 and must meet the requirements of Sanitary Rules No. 1042-73, which were approved by the USSR Ministry of Health and relate to the organization of technical processes. The concentration of harmful substances in the air during the production of bitumen roll material should not exceed permissible standards.

Fire hazard

Bikrost is a fire hazardous material. When laying a waterproofing coating or roofing carpet, an open fire is used. Therefore, working with welded material requires compliance with all fire safety requirements.

Storage

To avoid the wrappers sticking to each other, rolled material can only be stored in a vertical position, protected from precipitation and direct rays of the sun. The room must be dry. Storage temperature is not lower than -10 degrees, the distance to heating devices and heaters is at least 1 meter.

Bikrost - characteristics, application, price

One of the most commonly used materials for roof waterproofing and vapor barrier is bikrost, in which the low price of this material plays a significant role.
Physically, bikrost is a base made of fiberglass or fiberglass with layers of a mixture of bitumen and special fillers applied to it on both sides. These layers, in turn, are protected from exposure to the sun and other external influences by film and topping (for example, slate or sand).

You will learn about what types of bikrost there are, their technical characteristics, differences and application features by reading the article.

Types and characteristics of bicrost

In total, there are two categories of bikrost, marked with the letters K and P, each of which is divided into two more types - HKP, TKP and KhPP, TPP, respectively.

Bikrost HPP and HKP

Fiberglass is used as the basis for the production of CPP, and the layers of bitumen applied to it are covered with a special protective film that does not allow the layers to stick together. HPP can be used as a roof underlay, but cannot be used as a finishing roof covering, since it does not have a protective top layer.

Bikrost HPP, like roofing felt, can also be used for waterproofing during the construction of foundations and interfloor slabs.

The technical characteristics of bikrost HPP allow it to perform its functions for about 5 years. Despite the fact that the service life of the material is very short, this is compensated by its low price - in fact, it belongs to economy class products.

Bicrost HKP is very similar in its characteristics. Its only significant difference is the top layer of sprinkled crumbs. Thanks to this, it can be used as a roofing material, but only on roofs that do not experience heavy loads.

Bikrost Chamber of Commerce and Industry and TCH

Both types of bikrost use fiberglass rather than fiberglass as a base, which makes the material very durable. Otherwise, the differences are minimal - the same two layers of bitumen, covered with a protective film on the bottom side. However, the top side coverage of TPP and TKP is different:

• bikrost TPP has a top layer coating similar to the bottom one, that is, film. This allows it to be used as a lining material. The service life of this type of bikrost is about 7 years;
• the top layer is a topping in the form of fine sand or shale. The technical characteristics of bikrost TKP allow it to withstand any temperature changes and very high pressure, and the protective layer prevents the harmful effects of precipitation and sunlight.

Dimensions, weight and thickness

Bicrost is produced exclusively in the form of rolls, the width of which is always 1 meter, and the length varies - for category K it is 10 meters, and for category P it is 15 meters.

Due to its characteristics, we can only talk about the weight of bikrost in terms of the weight of 1 square meter. m, and it is equal to 4.5 kg for material of type K and 3.5 kg for type P. The thickness of the bikrost is 3.7 and 2.7 mm for insulation of types K and P, respectively.

How much does bikrost cost?

As for the price, it all depends mainly on the base, and, as a consequence, the strength of the material. On average, the price for each type of bikrost is:

• CPP will cost the least - only about 50 rubles / m 2 (accordingly, a roll will cost 750 rubles);
• CCP is sold a little more expensive - 60 rubles/m2 or 600 rubles per roll;
• the cost of the Chamber of Commerce and Industry is almost the same - 61 rubles/m2;
• buying bikrost TKP will cost your wallet the most - almost 70 rubles / m 2 or 700 rubles per roll.

• home
• Construction materials

Bikrost TCH

The most expensive of the roofing materials produced by Bikrost TechnoNIKOL is the TKP series. It is approximately 15% more expensive than the economy versions of HKP and HPP. This material is intended for the most heavily loaded roofing options, so its strength characteristics are noticeably higher.

Main operational characteristics of Bikrost TKP and TPP

When developing roofing materials, TechnoNIKOL created coatings with a wide variety of properties and characteristics.

The most common form of roofing made from rolled roofing materials is considered to be a two-layer version with a soft and elastic backing and a durable outer layer. Most often, for the roofing of large flat roofs, the following is used:

• To create a durable top layer - Bikrost TKP;
• Bikrost TPP is laid as a soft insulating coating;
• Combination of Bicrost TCH with CPP and EPP.

Structure and purpose

The Bikrost TKP device differs little in characteristics and materials used from other waterproofing options with a fiberglass-based reinforcing layer. Fiberglass fabric of a special weave allows you to get a thin, but very durable and flexible frame. To improve adhesion to the insulating layer, the fibers are treated with an adhesive composition that significantly improves adhesion to the waterproofing layer based on modified bitumen or petroleum compositions.

Application and technical characteristics

The description provided by Technonikol allows us to clarify some of the performance characteristics of the roofing material:

• The use of frame fiberglass fabric, in contrast to perforated canvas, allows for maximum rigidity in the longitudinal direction; the strength characteristics in the transverse direction approximately correspond to the HKP and EKP brands. Tensile strength is approximately double that of canvas and polyester frames;
• At the final stage of production, the top layer of modified bitumen is treated with styrene-based polymers, thus ensuring high strength and resistance of the material to abrasion and ultraviolet radiation. Water absorption characteristics remain unchanged throughout the entire warranty period;
• With a web thickness of 3.6 mm, Bikrost brand TKP has the same temperature flexibility as materials HPP and TPP;
• Bikrost brand TKP, like most TechnoNIKOL roll materials with a top layer treated with mineral chips, remains flexible up to a temperature of 0 o C; cracks in the insulating bitumen layer appear when the web is bent at a temperature of -15 o C.

Material laying practice

After hardening, the Bikrost TKP coating can withstand pressure of at least 20 kg per cm 2. The technical characteristics of the material practically do not change up to a temperature of 60 o C; at a higher temperature, the insulating coating begins to intensively soften, and at 80 o C the bitumen turns into a viscous liquid mass. This should be taken into account when performing construction work on a finished roof of the TKP series. At noon on a hot summer day, the surface temperature can reach 50-60 o C, so during this period it is not recommended to be on a flexible roof or carry out any construction work.

Mineral granules imprinted into the top layer of the Bikrost TKP coating significantly increase resistance to ultraviolet radiation and sunlight. Slate flake particles have the best protective characteristics, giving the characteristic gray color to the material. In some cases, in areas with hot climates, homemade protection from sunlight and heat is used. To do this, a thin layer of sand and chalk grits is scattered onto the surface of the Bikrost TKP. After this treatment, the protective characteristics of the powder are improved at least twice.

The high strength characteristics of Bikrost TKP make it possible to perform roofing coverings on roof slopes with an inclination angle of 15-30 o C. In these cases, it is recommended to lay the covering from the lower edge, rolling the roll towards the upper edge. This ensures uniform distribution of fused bitumen at the points of contact between the canvas and the surface of the slope.

The water absorption characteristics of the material are such that during the day, a canvas completely immersed in liquid accumulates no more than 1% water. The ability of Bikrost TKP to retain water, according to TechnoNIKOL specialists, is absolute. This means that the ability to retain water on the roof surface of Bikrost TKP corresponds to the characteristics of heavy concrete or rubber.

The main method of laying the sheet on the roof surface is surfacing using a gas burner. Before laying, the surface is cleaned, freed from dust and dirt, the edge of the roll is fixed with soldering, the rest of the sheet is unwound, heated and evenly laid on the surface of the slope. In some cases, it is possible to perform a single-layer roof.

The characteristics of such a roof will be practically the same as a two-layer roof if, before laying, the concrete surface of the base is treated with a primer or bitumen diluted in a solvent. This preparation can significantly increase the quality of adhesion to the base and in some cases is used as a means to prevent the occurrence of bubbles.

Conclusion

High mechanical characteristics and good durability of the material, despite the high price, have made it one of the most popular roofing coverings. According to reviews from roofers, the use of Bikrost TKP has always given a stable result, even on roofs with complex surface topography.

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 of rolled 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 floors, 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;
• replacement of old 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.

At the initial stage, preliminary preparation of the roof should be performed. 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 treatment before further installation of new waterproofing.

The next step is the actual processing of the rough surface. 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 cracks are filled with bitumen mastic, which can plug defects, returning the material to its original properties. However, this method is applicable only in cases where the total area of ​​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 the subsequent adhesion of bikrost to the old insulating material and to prevent delamination of the roof.

Now you can get to work with bicrost. Since it is sold in rolls, before you start laying it you need to roll it out on a flat surface and leave it 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. To do this, you will need a propane or butane gas torch.

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 a 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 that are in greatest demand are KhPP, TKP, KhKP, TPP; 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. The upper part of the rolled material is covered with a protective film that prevents the 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 type of bikrost has good mechanical strength and is used primarily for inversion roofs.
• Bikrost Chamber of Commerce and Industry It basically contains frame fiberglass, which is covered with bitumen layers on both sides. Therefore, this type of 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, bikrost should only be stored indoors, away from direct sunlight and precipitation, at a temperature not lower than -10 ℃.

Results

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

The weld-on material Bikrost is one of the types of roll waterproofing on a synthetic basis produced by the TechnoNIKOL company. It is used for arranging multi-layer soft roofing. Installation of such a roof is carried out in the form of a waterproofing carpet. It consists of 2-4 layers of rolled materials glued together. The protective structure in the form of a membrane ensures 100% waterproofing of the roofing system and has excellent performance properties.

Technical characteristics, features

Bikrost is characterized by a multilayer structure. Mechanical strength is determined by the reinforcing polyester or fiberglass base. Waterproofing functions are performed by bitumen binder modified with polymers - artificial styrene-butadiene rubber "SBS" and plastic "APP" ( atactic polypropylene). Depending on the type of modifier in the roofing material, its hardness and softening temperature are regulated.
A protective layer is applied to the upper surface of the roll, protecting the base from atmospheric influences and ultraviolet radiation. It consists of a polymer film and mineral coating. Sand is used as fine-grained topping material, crushed shale and asbagal are used as coarse-grained topping material. The rolls are laid on the prepared surface using a special technology. For good adhesion to the base, primer and mastic are used. The rolls are glued together by heating the mounting layer using a gas burner.
Bikrost roofing material is used for roofing of varying complexity in construction and repairs. It is also used to waterproof building structures.
The TechnoNIKOL company produces the following brands of these products:

• "Bikrost P";
• "Bikrost K"

Bikrost P rolls are made with an outer layer of polyethylene film with fine-grained topping ( sand). This type of rolled waterproofing material is used to construct the lower layers of a protective carpet (multilayer membrane). They also waterproof various internal building structures. Rolled waterproofing Bikrost K has an outer layer of coarse granules. Such rolls are used for laying the outer layer of roofing carpet. They provide increased protective properties against a complex of adverse effects.

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 works for various purposes (protection of the lower and upper 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 make the right choice. Bikrost based on fiberglass is used mainly for waterproofing and roofing work on non-load-bearing roofs with a low slope, which during operation do not experience tensile and 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 the installation of flat roofs up to those in use. 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 subsequently laid.

As a rule, the base is a concrete screed; it must be dusted 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 sheets must 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, bitumen adhesive mastics are used for gluing rolled bitumen materials.
