Damp proofing is an essential part of building which greatly reduces the risk of water damage to properties. Without the addition of damp proof coursing (DPC) and damp proof membranes (DPM), excess moisture and rising damp leads to deterioration of walls and foundations, as well as poor insulation, slip hazards and other problems. Water and damp proofing can prevent this, helping to avoid expensive repairs later on. Our range of damp proof membranes for walls are available in differing sizes and thicknesses, and made to protect walls and floors from moisture ingress. They work by actively stopping water from reaching the surface of walls and floors, protecting them from any further damage. Damp proof course is designed to work with brickwork to stop water from rising through bricks and blocks, preventing rising damp. Choose suitable sizes and amounts for large or small projects today.
