Damp Proofing

Damp proofing in construction is a form of moisture control applied to building walls and floors to prevent moisture from passing into the interior spaces. Damp problems are one of the most frequent problems encountered in homes.

DPC stands for damp-proof course and is a waterproofing barrier through the structure to prevent damp rising from the ground into your property. A DPC layer can be horizontal or vertical and is usually laid below all masonry walls, regardless if the wall is a load bearing wall or a partition wall.

DPM stands for damp-proof membrane and is a material applied to prevent moisture transmission. A common example is polyethylene sheeting laid under a concrete slab to prevent the concrete from gaining moisture through capillary action.

Sheet Membranes
Sheet membranes are flexible self-adhering rubberized asphalt sheets suited for below-grade waterproofing of foundation walls, tunnels, earth shelters, ICF forms and similar structures.
