A Damp Proof Course (DPC) is a crucial component of building construction designed to prevent moisture or dampness from rising through the walls of a structure.
Dampness in buildings can lead to various problems, including mould growth, structural damage, and health issues. DPCs serve as a barrier to block the capillary action of moisture, keeping the interior of a building dry and free from damp-related issues.
There are several types of DPCs, with the most common being:
This is typically installed at the base of walls, just above ground level, to prevent rising dampness. It can be made from various materials, including plastic, bitumen, or slate.
Vertical DPCs are used to create a moisture barrier in cavity walls. They are typically installed in the form of a continuous strip along the height of the wall, preventing moisture from travelling laterally from the outer to the inner wall leaf.
In some cases, a chemical DPC is applied by injecting a chemical solution into the masonry to create a moisture-resistant barrier. This method is often used in retrofitting older buildings.
The importance of a well-installed DPC cannot be overstated. It safeguards the structural integrity of the building, prevents damage to interior finishes, and protects the health of occupants by preventing the growth of mould and mildew.
