A damp proof membrane (DPM) is a thin, sheet material made of polyethylene, bitumen, or other water-resistant synthetic materials, used in construction to prevent moisture from the ground or other sources from migrating through building elements like floors and walls. By creating a continuous barrier, DPMs protect against dampness, reduce energy loss, extend the building's lifespan, and safeguard the interior's aesthetics. They are typically installed under concrete slabs or within walls, often sealed to form a complete barrier around the building's ground floor perimeter.
