To ensure that a building is adequately protected against moisture, prescribed standards should be observed. The water or moisture acting on the building from the outside can cause damage to and in the building if faulty constructions in terms of building physics do not provide sufficient heat and moisture protection. In addition, the ventilation behavior of the occupants influences the moisture content of the air.
A building is exposed to various water sources and influences. These include, for example, rainwater and spray water, soil moisture, pressurized water and non-pressurized water, but also building moisture, condensation and water vapor. The groundwater level also plays an important role. In order to seal a building well from the outside and provide protection against water ingress, the standards from DIN 4095 "Building ground - Drainage for the protection of structural installations - Planning, dimensioning and execution" should be observed.
On the subject of "waterproofing", the standards from DIN 18195 "Waterproofing of structures" apply, as well as regulations relating, for example, to the waterproofing of balconies and loggias, interior spaces and traffic areas that can be driven on (DIN 18531 to DIN 18535). Calculations of condensation failure should already be part of the planning of the building application; the air tightness of buildings or calculations of vapor pressure distribution also play an important role. The specialist portal "Baunetz Wissen" provides information on important aspects and requirements for moisture protection in buildings.
