What is the most important element in warming and protecting any building from excessive moisture? Of course, a waterproofing film (or superdiffusion membrane, waterproofing, hydrobarrier), which is an element of a facade or roof structure that allows air to pass through but retains water.
The distinctive features it possesses can be summed up in two words - hydrophobicity and vapor permeability. The most important aspect, which, first of all, you need to pay attention to when choosing this material is the ability to pass air. Thanks to this property, the film can “breathe”, which makes it possible to significantly extend the service life of any structure.
It should be noted that the color of the material does not matter, because all samples have almost the same characteristics. You can find white, colored, black or transparent waterproofing films on the market, which are usually sold in rolls, which makes them much easier to use.
Waterproofing film consists of three layers: middle - reinforcing, inin the form of a mesh of polyethylene fibers, and on the outside - two layers of polyethylene film.
It comes in two types - flat and perforated. The flat one is used for waterproofing foundation masonry, when installing floors on open ground, installing floor coverings, etc. Such a film is the most resistant and resistant to various chemical influences.
Perforated waterproofing film is used to protect against moisture the foundation or basement parts of the building, etc., and for the insulation of "green" roofs (on which it is planned to later place a lawn or a flat-shaped flower garden) - this is the best option. The special cells of this film create a small space between the surface to which it adjoins and the film itself, in which steam circulates without interference, and released moisture flows into it.
Waterproofing film, due to its properties, has found wide application. So, it is used to insulate roofing walls, basements and foundations, pools, etc.
Compared to other waterproofing methods, it has the following advantages:
- Resistant to UV rays.
- Service life is about 50 years.
- Increased resistance to negative external factors - decay, oxidation, etc.
- Waterproofing film is absolutely safe for the environment and humans.
- Retaining elasticity in any temperature conditions (from -40 °С to + 50 °С).
- Reliability of the structure helps to resist anymechanical damage - punctures, minor impacts, germination of tree roots, etc.
- Virtually non-corrosive.
- Resistant to many household chemicals.
The use of a waterproofing film is also advisable in order to save money, since when using it, costly concrete work is completely excluded. And thanks to the ease of installation, the work is done in the shortest possible time.
