For wall integrality preserving water proofing if being conducted in the apartment that consists of special composition application. As a rule this is a plaster waterproofing — cheap and effective.
Excessive humidity causes
Walls soak up humidity out of the air. And on the first floor it is more rich with aqueous vapor because of the basement proximity. The ventilation doesn’t always cope with humid air inflow, especially in modern houses with its blind metallic doors and vinyl windows. Also humidity can penetrate through constructions, in other words through walls coming up from the basement.
In apartments on the last floor the water penetrates through the roofing imperfections. This happens some day so any roof starts to leak sooner or later, and may be sheet-metal workers have done their job bad from the very beginning.
The humidity carves construction decorative elements, makes them weaker. The plaster becomes loose, the brick scales off, the ferro-concrete carcass corrodes, wallpaper fall off.
Walls excessive humidity leads to unwanted living creatures appearance. It can be fungus, mould, the observable part of which literally eats the surface and makes it terrible in view, and invisible flying spores harm health. Also in constantly humid rooms different suspicious microorganisms occur.
Wall humidity protection
Waterproofing walls inside in the apartment is a simple process and it is quite easy to make it by yourself. It is all about special thin layer mortar application to walls. Plaster waterproofing is a perfect agent that is similar to common plaster in composition, but it includes some modifications.
Once the plastered surface has moistened to certain condition, waterproofing components start to penetrate wall structure for some depth. As the treatment modifying agents close up capillary pods. Now water won’t be able to accumulate in walls – it means that there won’t be any damages and conditions for fungus occurrence won’t appear. At that air-interchanger processes don’t worsen, more simply the room becomes a thermos and its walls are still “breathing”.
Of course, waterproofing walls inside the apartment won’t help when the roof is slim or the basement is full of water. In this cases you need to lag the roof, pump out water and make waterproofing exterior.
However, waterproofing inside won’t hurt because nobody knows if the roof leaks, or the tube cracks, or your neighbors drown you, or the ventilation breaks. If plaster waterproofing has already been applied to walls, the apartment will stay unhurt in case of excessive humidity and flooding and owners will have less troubles with next repair.
