DPM

Protect floors and foundations from moisture with our range of DPM (Damp Proof Membrane) products, essential for long-lasting building and renovation work. A damp proof membrane is designed to create a barrier that helps prevent moisture rising through concrete and floor structures, reducing the risk of damp patches, mould, and damage to floor finishes over time. Whether you’re preparing a new slab, laying flooring, or working on an extension, using the right DPM helps improve durability and overall build quality.

DPM is commonly used beneath concrete floors, screeds and ground-bearing slabs, helping control moisture movement and support a drier internal environment. It’s also used in a wide range of domestic and commercial projects where reliable moisture protection is required. Choosing the correct thickness and installing it properly—without tears or gaps—helps ensure consistent performance and better long-term protection.

For best results, lay DPM on a smooth base, overlap joints correctly, tape or seal where required, and protect the membrane during installation to avoid damage. With the right preparation, a good DPM helps prevent future problems and supports a stronger finish.
