Damp Proof Membranes (DPM)

Damp proof membranes (DPMs) and cavity closers block moisture from moving through floors and walls. They keep buildings dry and protect timber and finishes. Builders, bricklayers and DIYers use them on new builds and renovation projects.

Our range includes durable DPM sheets, cavity closers and matching accessories. You’ll find sizes for floors, walls and junctions in brick or block work. These products help control rising and penetrating damp at critical points.

Use these membranes and closers to stop damp before it starts and make structures weather-secure. They help maintain dry interiors and reduce long-term maintenance issues. Choose the right type for your cavity depth and ground conditions to match site requirements.
