Feuchteinstätzungen

Feuchteinstätzungen refers to the phenomenon of moisture penetration and accumulation within building structures. This can occur through various pathways, including rising damp from the ground, penetrating damp from external sources like rain or leaks, and interstitial condensation within the building fabric. Rising damp is typically caused by groundwater being drawn up through porous building materials like brick or stone due to capillary action. Penetrating damp often results from structural defects such as cracked render, damaged pointing, faulty gutters, or leaking pipes. Interstitial condensation forms when warm, moist air within the building comes into contact with cold surfaces within the wall or roof structure, causing the moisture to condense.

The presence of Feuchteinstätzungen can lead to a range of detrimental effects. It can compromise the thermal insulation performance of the building, leading to increased heating costs and a less comfortable indoor environment. Furthermore, persistent moisture can damage building materials, causing rot in timber elements, spalling of brickwork, and the degradation of plaster and paint finishes. It also creates an environment conducive to the growth of mold, mildew, and other fungi, which can have negative impacts on indoor air quality and occupant health, potentially causing respiratory problems and allergic reactions.

Identifying and addressing Feuchteinstätzungen requires a thorough assessment of the building. This often involves moisture mapping, thermal imaging, and an analysis of the building's construction and any potential sources of moisture. Remedial measures vary depending on the cause and extent of the problem. They may include improving drainage around the building, repairing external defects, installing damp-proof courses or membranes, enhancing ventilation to reduce interstitial condensation, and using breathable finishes to allow moisture to escape.
