Rising damp is a form of dampness that occurs, particularly in older buildings, when groundwater rises up through walls, floors and masonry via capillary action, which is the ability of a liquid to flow in narrow spaces in opposition to gravity.
The most common visual symptom of rising damp is a clearly defined band of dampness, starting from the floor upwards – often causing paint to flake or wallpaper to peel. However damp walls, caused by rising damp, can also result in a wide range of other symptoms
