UNDERGROUND WATERPROOFING
In order for the underground parts of buildings to be used for various purposes, they must be protected against moisture and water ingress. In modern construction, increasing attention is being paid to underground sections of buildings, especially in cases where completely dry rooms are required.
The nature of water in the soil can vary depending on the impermeability and water-retaining capacity of the terrain. The following types of water in the soil are distinguished:
-
Groundwater
-
Collected (retained) water
-
Capillary water
-
Seepage water
-
Adhesion water
-
Adsorption water
In principle, depending on the type of water the structure is being protected from, three basic groups of waterproofing systems are differentiated:
-
Waterproofing systems against moisture
-
Waterproofing systems against moisture and non-pressurized water
-
Waterproofing systems against pressurized water
Waterproofing of underground building sections can be executed using the following technical solutions:
-
Bituminous waterproofing
-
Waterproofing (synthetic) membranes
-
Crystalline coatings (penetrants)
-
Concrete additives for waterproofing
