Polythene Damp Proof Membrane (DPM) - Black/Grey 4m x 25m (100m2)

Polythene Damp Proof Membrane (DPM) Black/Grey 4m x 25m (100m²)

This BBA certified polythene damp proof membrane is a low-density, high tear-resistant sheet designed to prevent the ingress of moisture from the ground into buildings. Used beneath concrete floor slabs and ground-bearing screeds, it forms a continuous barrier against rising damp and ground moisture, helping to protect floor finishes and maintain a dry interior environment.
