Factors initiating destructive processes and causing the most threats in construction facilities are: water, moisture, salts, acids and principles that cause all kinds of mold, fungi, salted erosions and erosions of walls. They occur in rain, snow, fog, or in groundwater and destroy, among others foundations of buildings, walls and other parts of overground and underground construction facilities.
Incorrectly placed or damaged horizontal insulation of foundation walls, or complete absence of such insulation, leads to capillary action of groundwater. Using micro canals, water particles migrate to the areas with lower moisture content. Rising damp is the cause of technical degradation, the result of which are salt deposits, falling off of plaster, or damage of foundation walls and walls of higher floors. It is of utmost importance to stop this process.
There are various – more or less effective – chemical, mechanical or gravitomagnetic methods which secure against rising damp. During renovation, installation of horizontal insulation by means of cutting a building's walls is very important. The works which are conducted in a professional manner ensure 100% protection against the action of capillary moisture.
