Rising dampness is a serious building issue caused by moisture rising from the ground into walls through capillary action. It usually occurs when the damp proof course is absent, damaged, or poorly installed. This problem leads to visible signs such as peeling paint, damp patches, salt deposits, mold growth, and unpleasant odors. Over time, rising dampness can weaken plaster, brickwork, and overall structural strength. It also affects indoor air quality and can cause health issues. Proper waterproofing solutions like chemical damp proof treatment, injections, or barrier systems are necessary to stop moisture movement and protect the building long term.
