DPM Damp Proof Membrane

Our heavy-duty DPM damp proof membrane is the most commonly used damp proof membrane in the UK building industry. Laid under floors, it forms a continuous barrier that stops moisture rising from concrete and other subfloors into your flooring, underlay and screed.

1000 gauge protection. At 250 microns (0.25mm), this 1000 gauge DPM membrane is tough enough for site use and resists tearing as you lay it. It's made from 100% recycled polythene, which makes it an economical and environmentally friendly choice.

Buy exactly what you need. The membrane comes in 4m wide rolls, supplied folded to 1m for easy handling. We sell it by the square metre, so you don't need to buy a full 100m² roll for a single room.
