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. Damp Proof Courses block capillary action, keeping building interiors dry and free from damp issues, serving as a crucial barrier.
There are several types of DPCs, with the most common being:
Horizontal DPC:
Install this just above ground level at the base of the walls to prevent rising dampness. Make it from various materials, including plastic, bitumen, or slate.
Vertical DPC:
Use vertical DPCs to create a moisture barrier in cavity walls. Install a continuous strip along the wall to prevent lateral moisture travel from the outer to the inner wall.
Chemical DPC:
In some cases, inject a chemical solution into the masonry to create a moisture-resistant barrier as a chemical DPC. This method is often used in retrofitting older buildings.
We cannot overstate the importance of installing a DPC effectively. 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.
