Rising Damp

Rising damp is moisture that soaks into the structure of the house from the ground. Foundations are designed to cope with damp soil and generally won't have any problems, likewise any concrete below DPC. However, if the damp crosses the DPC or crosses from the subfloor into joists or finished floor and carpet, it can cause serious problems. Like penetrating damp, it can cause structural problems, mould growths, rotten skirting boards and behind skirting tiles will cause problems. Usually, rising damp is the most difficult to put right, costs more but very effective the longer it's left untreated and takes longer than all the other types to remedy.
