Wall draining

from Wikipedia, the free encyclopedia

Under a Mauertrockenlegung covers all measures for the removal of moisture that has penetrated into masonry, including prevention of moisture absorption by methods of waterproofing of buildings , wherein the moisture is added either as a liquid or as a vapor (of which the countermeasure dependent):

Moisture absorption

Drying process

Sealing method (masonry sealing)

Possible structural damage

Damp walls can cause structural damage, for example

  • Transport of soluble salts which can destroy the plaster when crystallizing out , see efflorescence
  • Mold spots , black mold
  • Frost damage as a result of moisture absorption
  • Binder conversion and redistribution, especially with natural stones and plasters
  • Discoloration of the building material surface due to salt formation (e.g. natural stones that contain iron compounds)
