Dpm Membrane / Dump Proof Membrane

A damp proof membrane (DPM) is a protective barrier, usually made from polyethylene or EPDM, designed to prevent moisture from passing through walls, floors, or foundations. It is installed in building structures to stop rising damp, condensation, or water ingress. Durable and flexible, DPM safeguards against structural damage, mold growth, and maintains a healthy indoor environment.
