Rising Damp Guides
Rising damp is groundwater moving up through porous masonry by capillary action. It typically reaches 1-1.5 metres above ground level and is most common in pre-1875 buildings without a damp proof course. These guides explain how rising damp works, how to identify it, and how to treat it permanently.
