Waterproofing film: application features
Waterproofing film is one of the typespolymer films, which is in high demand. When carrying out work on waterproofing it is important to know the specifics of using such material, otherwise your time and effort will be wasted.
Waterproofing - mandatory technologicaloperation for each structure. This is the most important element of construction, on the quality of which the life of the structure depends. Waterproofing of building structures is carried out using a special film, which has different names: waterproofing film, hydro-barrier or super-diffusion membrane.
Properties of waterproofing film
A distinctive feature of the waterproofing film are its two properties: vapor permeability and hydrophobicity. In a word, such a film lets in air, but does not allow water to pass through. Water vapor permeability
This is the ability of the material to align the partialwater vapor pressure from both sides at equal atmospheric pressure. This means that the entire construction of the building can "breathe", and this greatly extends the life of any structure. Hydrophobicity
Barrier for water are three layers of waterproofing film: medium, which consists of strong polyethylene fibers, and two outer layers consisting of high-quality polyethylene. Types of waterproofing film
Waterproofing film is available in two types: flat and perforated. The first option is used for waterproofing brickwork, starting from the foundation, as well as for the installation of floor coverings, the protection of floors in open ground conditions. This kind of film is extremely resistant to chemicals. Perforated film has special cells in which water vapor can circulate at the material interface and moisture condense. This film is used to protect the foundations, basement and basement parts of the building, as well as for the organization of "green" roofs. Perforated film is the best option for flower beds and lawns on roofs and window sills. Features of waterproofing film application
1. It is necessary to accurately observe the purpose of the flat and perforated film. Before laying the material, it is necessary to level the surface and make sure that there are no sharp small objects and lumps on it that can disrupt the integrity of the waterproofing film. It is important to carefully study the instructions for the film, especially the paragraph describing which side to lay the material. Usually all modern waterproofing films are double-sided, however, a one-sided version can also come on the market. It is not recommended to allow contact between the waterproofing film and the insulation, as the film may lose its vapor permeability properties. 5. The overlap width at installation of a film should make 8-10 sm.6. Seal the overlap of sheets with the help of a mounting adhesive tape. The color of the film does not matter.
