In principle all concrete floors should include a damp proof membrane across the whole floor area and this should be linked to the damp proof courses in the surrounding walls to provide continuity of protection against ground moisture.

Damp rising through concrete floor slabs is fairly common, causing damp issues on carpets and floor coverings, warping wooden floors and increasing the likelihood of low-level mould growth.

A Damp Proof Membrane or DPM is a waterproof barrier that’s introduced between your sub floor and your wood floor. Effectively a thick plastic sheet, a damp proof membrane (DPM) is used to create a barrier between a concrete (or screed) subfloor and a wood floor.

This barrier is intended to stop moisture passing from one to the other. Most of a building’s problems can be traced to moisture. It causes wood to decay, concrete to crack, fungus to grow, metals to corrode, pipes to burst (from the cycle of freezing and thawing), and it damages and discolours interior finishes.
