Bikrost, the technical characteristics of which are of interest to many professionals and home masters today, is popular in the building materials market. It is a roofing material that is applied by welding and has waterproofing characteristics.
Description of Bikrost
Bikrost was introduced to the general consumer in the 90s. Its use made it easier to carry out repair work in the field of roofs. The material copes with the tasks of a quality waterproofing system. Over time, it does not rot, as it is based on fiberglass, which is sometimes replaced by fiberglass. A high quality binder is used as the top layer. Bikrost, the technical characteristics of which force consumers to tip their choice in his direction, has a relatively low cost. This can be verified by comparing the material with analogues. A square meter of the described material has 3.5-4 kg of binder, while the protection task is assigned to coarse-grained sprinkling, which can be scaly, fine-grained or dusty.
Bikrost Cost
Bikrost, whose technical characteristics affect the cost, can be purchased for a price of 50 rubles / m 2 . Varieties of material will be described in more detail below.
Specifications
The described material has the ability to not burst when stretched. This is very important for roofing, which will constantly undergo loads from snow. So, the breaking strength at the moment of stretching is N / 50 mm, which is true at 294-343 kgf. The canvas almost does not absorb moisture, the level of water absorption is 1%. At zero degrees, the material shows flexibility on the rod within R = 25 mm. But the initial fragility is achieved at minus 15 ° C.
Bikrost, the technical characteristics of which attract not only private developers, but also professionals, shows resistance for two hours when exposed to temperatures within +80 ° . After laying, you can be sure that the roof will not require repair for 10 years. In fact, this period is much longer.
The material has a dusty or fine-grained powder, which acts as a protection of the deposited film from the sticking process. Bikrost is not afraid of fungi, microorganisms, as well as insects.
Area of use
Bikrost is used for waterproofing roofs, foundations, basement walls, ceilings, pools, main piping systems, as well as all kinds of structures.
Pros of Bikrost
- Long service life.
- Water repellent.
- Excellent margin of safety.
- Unique qualities of heat resistance.
- Ease of installation.
- Ability to work with bikrost at low temperatures.
- An opportunity to make laying on any bases.
- Ability to noise absorption.
Varieties of Bikrost
Bikrost HPP , the technical characteristics of which allow using the material as the lower layer of the roof, is represented by the simplest kind of material. This type of bicrost is based on fiberglass, on which a bitumen layer with a number of additional additives is applied. On both sides, bitumen is coated in the form of a plastic film.
Bikrost HKP , the technical characteristics of which are similar to HPP in that fiberglass is also used as a base here, is no less impressive. While bitumen has a protective plastic film on the lower side and a sprinkling of fine-grained slate on top, manufacturers can replace the last component with granulate. Topping is intended to increase the strength characteristics of the material, reducing the harmful effects of solar radiation.
Bikrost TKP , the technical characteristics of which involve the use of fiberglass as the basis, is covered with a sprinkle on top and a protective film on the bottom. Such a combination allows the use of the material even on inverse roofs. The qualities of this kind of bicrost are better compared to the one that is based on fiberglass. It is used in the device of the upper roofing layer.
There is another variety, which is indicated by the acronym CCI. In this case, the material on both sides has a coating in the form of a film. In the role of the main layer is a frame fiberglass. In addition to those described, some other varieties of material can be distinguished; they are based on polyester, but are not so common today in the market of building materials.
Features of laying bicrost from Technonikol
Bikrost HPP, the technical characteristics of which were described above, fits into a certain technology. Observing it, you can count on a quality coating that will protect the roof from moisture. The material is glued after melting the bitumen component. To do this, it is recommended to use a gas burner. In addition, you should use a special hook that allows you to roll out rolls that are bicrost material. Technical characteristics of TechnoNIKOL material allow creating coatings that serve for a long time. However, it is important to check that the surface is hard and dry before laying the birostrost.
To do this, the base should be cleaned of debris and the old roof. After that, it is worth applying a primer or bitumen to the base, which must first be diluted with gasoline to a liquid consistency. After application, the composition should be left to dry completely. It is recommended to roll the roll perpendicular to the slope, cut to the size of the surface and start heating with the burner. The treated area should be rolled along the roof with a hook. It is unacceptable to move around the newly hardened material so as not to damage it. The next sheet should be stacked with an overlap of 10 cm.
Self-laying of the material is possible without additional help, this will save on roofing work.
