Whatever the construction stage of the construction of the waterproofing of the foundation, it will always be appropriate and relevant. Even if the house has already been built, and it still does not have protection against moisture, then in this case you can correct this significant defect with your own hands.
Conducting waterproofing work will be different for different types of foundations, and also depend on the composition of groundwater and the level of their occurrence.
The initial stage of work
The base of the foundation is dug up along the external perimeter. The width of the trench is determined by the convenience for work, but, as a rule, does not exceed 1 meter. The depth should be below the very sole of the foundation by 50 cm.
This will be equipped with the most effective drainage system that increases the life of waterproofing by half.
Do -it -yourself waterproofing the foundation, made using high -quality materials and, subject to technology, may not yield to the quality of the work of professionals.
Waterproofing of a prefabricated and monolithic strip foundation.
There are several ways to protect such a foundation.
1) coating. Various mastics are used. As the most economical option, it is the most short -lived. This type of protection against moisture begins to be damaged not only during operation, but already with reverse filling of the pit with a soil containing fragments of stones, reinforcement and glass.
The main thing in carrying out the work of coating mastic should be applied to the extremely even and previously well -dried surface. Outside, waterproofing is protected by a clamping wall of brick (difficult and expensive), ordinary insulation or roller geotextile.
2) roller waterproofing. As a rule, roofing material is used. The process technology comes down to the following: the dry and even surface of the foundation should first be treated with hot mastic of bitumen, and then glue several layers of roofing material overlair by 20 cm.
3) sprayed waterproofing. It is applied with a special sprayer quickly and quite easy even on the irregularities of the foundation. Pre -preparation of the surface is not required only to remove dust and dry.
Then reinforcement is carried out by geotextiles, additionally performing the protective function.
4) penetrating waterproofing. A special mixture of quartz sand, cement and special additives is used. The mixture fills the pores of the foundation, creating reliable protection against moisture penetration.
This is an expensive way, but very effective.
Waterproofing of a slate monolithic foundation
A roll roofing material is laid on top of the foundation tile, then a layer of insulation. And then a finish screed is made on it.
Waterproofing of a columnar or pile foundation.
It is carried out by grillage. Piles or pillars are immediately made from special concrete with moisture -resistant additives. Wooden piles should be saturated with a protective solution during installation.
In this case, it will not be desirable to carry out drainage work, since the solution protects the tree from decay, and moisture impregnation will only increase the stability of the structure.
