Moscow region tightened quality control of capital repair

In the Moscow region, technical supervision has tightened the inspection of materials used in the overhaul of facades and roofs of apartment buildings. Now experts closely monitor how brick, insulation, wood and plaster are able to absorb moisture from the air.

If such materials gain water, they become deformed and lose their ability to retain heat. To prevent this from happening, samples undergo laboratory tests: they are weighed before and after being in a humid environment.

Hydrophobization is used for additional protection of structures. On the walls apply special compositions that repel water, but retain natural vapor permeability. This leaves the walls dry for many years.
