For many centuries waterproofing work was considered the most difficult, because the craftsmen had to work with a huge amount of tar in the liquid form, bitumen, breathe smoke and soot. Fortunately, roll materials have appeared. One of them from the manufacturer "TechnoNicol" has gained particular popularity. What is Bikrost HPP? This is the name of the modern material used for roofing work. It is distinguished by the quality of waterproofing and quick installation.
The manufacturer Technicol company offers a large number of roll materials. Bikrost is used when arranging the roof. Such a roof is of high quality and is affordable for buyers. The purpose of the material is to protect the premises from moisture and deformation of floors, load-bearing elements and property.
Especially flat and slightly sloping roofs need such a roof.
The main advantages of this roof are:
In one day it is able to absorb moisture in the amount of 1% of its own weight;
Despite the large number of advantages, disadvantages are still present.
Bikrost is produced in two types:
It has a bituminous base on both sides, and the top is covered with a low-melting film. Material thickness 2.7 mm;
Fiberglass, viscous bitumen, polymers can be the basis.
There are many types of material and to determine them, markings are used containing 3 letters of the following decoding:
The first letter indicates the base coat, the second indicates the surface coverage, and the third indicates the back cover.
The most popular varieties of Bikrost are KhPP, TKP, KhKP, CCI. The rest of the materials are also of high quality, but less purchased. In addition to the composition, the marking contains an indication of the mass, color of mineral chips, technical specifications. The composition affects the thickness of the material, which must also be taken into account when planning work.
Bikrost is produced in rolls 1 meter wide and 7-15 meters long. Weight varies from 30 to 45 kg depending on the footage. Material specifications differ. For example, consider several options:
Below is a layer of oxidized bitumen. Also, the roll is protected by a low-melting film.
According to its characteristics, this material is economical in price. The price per square meter varies from 50 to 70 rubles.
Bikrost HPP is more of a lining waterproofing material with a fiberglass base with a layer of bitumen on both sides. The top of the roll is covered with a protective film to prevent the layers from sticking together.Thus, Bikrost HPP is not used for other purposes due to its low mechanical strength.
The base made of glass fiber does not rot, does not break. Bitumen has an astringent property. For production, the company uses the most technologically advanced equipment, taking into account the latest trends.
. The material can withstand 30 or more kilograms of load without damaging the reinforcing tape and bitumen;
Important! It must be remembered that the HPP, unlike the HPC, does not have a protective layer, so you should not roll out the roll and step on the canvas.
Most often, such bikrost is used to overlap walls, cornices, in an area with ventilation pipes, and other elements. The thickness of the material is 2.6 mm, the absence of powder turns the HPP into an ideal substrate under the main layer of waterproofing.
If it is necessary to perform a single-layer waterproofing or soft roof, professionals recommend using a concrete base on which the HPP will lie.
The base should be thoroughly dried, heated, primed. All this will ensure better adhesion of the material to the surface.
If the surface is large in area, it is advisable to lay in several rolls at once in order to increase the strength of the coating.
The weight of the roll is 45 kg, the usable area is 14 square meters. One roll contains 15 meters of 1 meter wide canvas.
On the surface, you can see information about the material, batch, release date.
Service life of Bikrost HPP is from 7 years. If you make a layer twice or using HKP, then this figure increases to 12 years, increasing the operational characteristics of the roofing material. As a rule, single-layer coatings are used on temporary structures and during roof repairs. It can be used for waterproofing foundations, floors, basements and as a vapor barrier for garage roofs, screeds, swimming pools, bathrooms, pipes.
When buying material, you need to know that rolls are delivered on pallets. The weight of one pallet reaches 1035 kg. The canvases are installed vertically and protected by a shrink bag. To eliminate deformation, it is often possible to find heart-shaped cardboard sleeves in a roll. Each pallet has information about the manufacturer, batch number, shift, brand, number of meters, date of production, etc.
Bikrost HPP is regulated by TU 5774-042-00288739-99 and complies with SNiP 23-01.
It should be understood that bikrost rolls stick together, so they need to be stored only vertically, not on top of each other.If these conditions are not observed, bikrost will stick together and even special films will not protect. The rolls should stand in a dark and closed room, subject to a temperature regime of at least 10 degrees.
It is possible to independently cope with the installation of Bikrost without any problems.
Bikrost is easy to install and does not require special knowledge for this. You will need some tools and knowledge of the nuances, standards for laying.
It is recommended to adhere to the following list of works:
There are subtleties at this stage. For example, if cracks appear on the old roof, through which moisture penetrates, it is necessary to carry out repair work. For this, all cracks are filled with bituminous mastic for plugging. This method is used when the total area of damage is within the indicator of 10%.
In order for the bikrost to adhere firmly to the roof, it is heated by a special gas burner.
Work starts from the edge of the roof. The end of the roll heats up, presses against the roof and rolls slowly along the roof, not forgetting about heating. At the end of the work, for better grip, you need to roll the material with a manual heavy roller.
After laying the first roll, you need to immediately move on to the second, observing the rule of an overlap of 15 cm. In this way, complete tightness will be obtained, which will not allow moisture to get between the seams.
All seams are checked for tightness. Experts recommend to additionally warm up these places and once again roll with a roller. If it is impossible to eliminate the defect, bitumen mastic is poured between the seams.
Each buyer can find the best option for Bikrost, thanks to its variety and availability.
This material will adequately protect the roof for many years, and installation does not take much time and effort.
