Feuchteschutzschichten

Feuchteschutzschichten, often translated as damp-proofing layers or moisture barriers, are essential components in building construction designed to prevent the ingress of moisture into building structures. Their primary function is to protect materials from degradation caused by water, which can lead to issues like mold growth, rot, and structural weakening. These layers can be made from various materials, including bitumen, plastics like polyethylene and PVC, or special cementitious compounds.

The application of feuchteschutzschichten varies depending on their location within the building envelope. In basement construction, they are applied to the exterior of foundation walls to resist hydrostatic pressure and soil moisture. For roofs and walls, they act as vapor barriers or weather-resistive barriers, depending on their permeability. The selection of the appropriate feuchteschutzschicht depends on factors such as the type of moisture to be resisted (e.g., liquid water, water vapor), the environmental conditions, and the structural requirements. Proper installation is critical to ensure the effectiveness of these protective layers, as any gaps or breaches can compromise the entire system. Regular inspection and maintenance are also recommended to maintain their protective qualities over the lifespan of the building.
