Liquid Damp Proofing Membranes

DPM Liquid (Liquid Damp Proof Membrane) is a high-performance moisture barrier designed to prevent the passage of water vapour and rising damp through concrete floors, screeds, and masonry surfaces. Applied as a liquid coating, it cures to form a seamless, durable membrane that effectively protects internal finishes from moisture-related damage. Liquid DPMs  are commonly used during renovation or new-build projects where traditional sheet membranes may be impractical. They are ideal for use in basements, ground floors, garages, utility rooms, and anywhere that moisture ingress poses a risk. This type of damp proof membrane is also suitable as a surface preparation layer beneath flooring installations such as tiles, vinyl, laminate, or hardwood, helping ensure long-term durability and performance.
