What is the most important element in warming and protection against excessive moisture of any building? Of course, a waterproofing film (or a superdiffusive 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 that it possesses can be identified in two words - hydrophobicity and vapor permeability. The most important aspect that, first of all, you need to pay attention to when choosing this material is the ability to pass air. Due to this property, the film can "breathe", which makes it possible to significantly extend
the service life of any design.
It should be noted that the color of the material does not matter, because all the samples have almost the same characteristics. You can find white, color, black or transparent waterproofing films on the market, which are usually sold in rolls, which greatly facilitates their use.
The waterproofing film consists of three layers: the middle one is reinforcing, in the form of a mesh of polyethylene fibers, and on the outside two layers of polyethylene film.
It is of two types - flat and perforated. Flat is used for waterproofing foundation masonry, when installing the floor on open ground, installing flooring, etc. Such a film is the most resistant and resistant to various chemical influences.
Perforated waterproofing film is used to protect the foundation or basement of a building from moisture, etc., and to isolate "green" roofs (on which it is planned to subsequently place a lawn or flower bed of a flat shape) - this is the best option. The special cells of this film create between the surface to which it adjoins and the film itself a small space 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 for insulation of roofs of walls, basements and foundations, pools, etc.
Compared to other waterproofing methods, it has the following advantages:
- Resistance to the influence of ultraviolet rays.
- Service life is about 50 years.
- Increased resistance to the effects of negative external factors - decay, oxidation, etc.
- The waterproofing film is absolutely safe for the environment and humans.
- Preservation of elasticity in any temperature conditions (from -40 ° to + 50 ° ).
- The reliability of the structure helps to withstand any mechanical damage - punctures, minor bumps, sprouting of tree roots, etc.
- Virtually corrosion free.
- Resistant to many household chemicals.
The use of a waterproofing film is also advisable in order to save, since when it is used, expensive concrete work is completely excluded . And thanks to the ease of installation, work is done as soon as possible.
