Product Details

SAMAC Polythene DPM (Damp Proof Membrane) is a heavy-duty moisture barrier designed to prevent rising damp and ground moisture from penetrating concrete slabs and flooring systems. Commonly installed beneath concrete floors and screeds, this essential construction material ensures long-term protection of internal finishes and structural elements across residential and commercial builds.

Manufactured from high-quality polythene, SAMAC DPM offers excellent durability, flexibility, and resistance to punctures during installation. Typically supplied in trade-standard rolls (e.g. 4m x 25m), it provides wide coverage with minimal joints, improving installation efficiency on site. Conforming to recognised UK standards, damp proof membranes are widely used to create an effective barrier against moisture ingress in modern construction.
