Cause of rising damp

Rising damp is moisture that is absorbed by the building structure (and usually the foundation) as a result of contact with a damp or wet substrate. The capillary action of the walls ensures that the moisture is transported upwards with the known consequences such as:

  1. Mould formation on the wall
  2. Higher humidity
  3. Discolourations and moisture spots
  4. Moist walls (and loose wallpaper or paint)

Expressions of rising damp

Rising moisture always manifests itself just above the surface level. It is a phenomenon that cannot therefore occur on higher floors (moisture problems that occur there usually have to do with the passage of moisture).
