If the damp proof course is missing, or has otherwise failed, properties may exhibit signs of rising damp. Rising damp typically occurs if the built-in damp proof course is missing, is breached, for example by raising of ground levels, or is damaged, for example by a structural alteration.
In such cases rising damp may occur. The dampness may affect vulnerable materials or finishes that are in contact with the wall. Rising damp has potential to rot timber joists, skirting boards or the bottom of door frames or to cause wall plaster to flake and wall coverings to deteriorate or become stained.
