To increase the life of the building, it is very important to use the correct and high-quality waterproofing materials during the construction, since water and moisture are the first enemies in home.
Film for waterproofing is a special building material, the purpose of which is to protect structural elements from the effects of precipitation and condensation.
Today it is no longer possible to imagine any construction process without the use of a waterproofing film, because it is its presence that prolongs the life of the object, helps to keep the interior decoration of the walls and ceiling of the building longer.
Types of waterproofing film
There are currently the following types of film on the waterproofing market:
- Standard waterproofing film - made of polyethylene, used in the construction of saunas, swimming pools, basements, during repairs in bathrooms and laying underfloor heating.
- Antioxidant - widely used in roof repairs.
Due to its composition and special coating, it prevents condensation on the inside of corrugated board or metal tiles.
- Polypropylene diffusion - a film with a very complex structure, which promotes natural vapor exchange, while not allowing liquid to pass through.
- Super Diffusion Membrane is the best choice for roof waterproofing. The lower layer promotes air ventilation, and the upper layer prevents moisture from penetrating inside.
- Pseudo diffusion - practically not used, because, against the background of excellent waterproofing abilities, it has insufficient ventilation qualities.
Pros and cons
Like every building material, waterproofing film has a number of advantages and disadvantages. The advantages include:
- The strength of the membrane - it can withstand the installation process, exposure to strong winds and heavy snow.
- The film is not afraid of ultraviolet light, in the sun it does not lose its properties up to half a year, then a slow process of material destruction begins.
- Even under constant temperature fluctuations, the film quality remains unchanged.
- Low price
! Important. The waterproofing film is capable of withstanding temperatures from -40 ° to +80 °.
Compared to the advantages, the material has not so many disadvantages:
- It is problematic to mount on complex roof structures.
- Films from some manufacturers need to be mounted with an air gap created in advance, which requires more time and consumables (additional crate is created).
Where it is used
It is widely used for waterproofing structural elements in the capital construction of wooden houses, baths and even for creating an artificial pond.
The main purpose of using such membranes is to protect individual elements and the entire structure as a whole from premature destruction, namely:
Protect the foundation against moisture penetration into the pores of the concrete.
- The roof and walls are waterproofed to protect the insulation and interior decoration from the ingress of external moisture into the room.
- In addition, you can use a waterproofing film to protect the ceiling and floor of the interior of the house, it is especially recommended to use it when renovating the bathroom and kitchen.
How to choose
Now there are many polymer and bituminous materials that can be used to protect the foundation, roof and blind areas, the main thing is to choose the right one.
There are some tips to help you decide which membrane to choose.
- It is better to purchase material from a manufacturer proven over the years. Yes, the cost can be higher than that of lesser known manufacturers, but it guarantees a longer service life and higher quality.
- Assess the film properties correctly. For the foundation and blind areas, a film with high mechanical strength and water resistance is needed. And for the roof, ultraviolet resistance and the ability to vapor exchange are important.
- The film must be strong and elastic.
! Important. It is better to purchase films from well-known manufacturers such as TechnoNIKOL, Yutafol, Technoelast.
Each film has its own characteristics that must be considered when editing. If you do not follow the requirements, waterproofing can turn out to be of poor quality or short-lived, which is bad in any case.
Here are some tips:
Antioxidant the film must not be mounted in a period of high humidity. In addition, it is important to check that its adsorbent side lies on the insulation. Use galvanized nails for fastening.
- Superdiffuse and diffuse films are usually fixed with nails with a wide head.
- Install the vapor barrier foil together with the insulation.
A special tape or glue is used as fasteners.
Modern materials will easily help you create waterproofing of any complexity, while the working process itself is quite simple, in comparison with the use of liquid tar or mastics. Building materials made of bitumen or polymers are much better suited as waterproofing agents than powdered or liquid materials.
