Damp Proof Membranes

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.

Damp proof membranes (DPMs) can be used to help resolve damp issues that already exist or as a preventative measure to avoid damp or moisture problems in the future. The thickness and quality of the DPM you choose will affect how efficient it is and how long it will last. Commonly used in the foundations of new builds, it is only reasonable to accept and expect that DPMs have a limited lifespan. That said, this way of blocking moisture should be effective for a lengthy period.
