DPC
The document discusses damp proof courses (DPC), which are barriers made of impervious materials built into walls and piers to prevent moisture from moving within the building. A DPC is laid into a brick wall approximately two courses below the lowest timber member, such as a bearer. Damp proofing in construction uses moisture control methods applied to walls and floors to prevent damp problems from occurring inside buildings, including membrane damp proofing, integral damp proofing, surface treatments, guniting, and cavity wall construction.

- 1. DAMP PROOF COURSE Dampproof course (DPC) is a barrier of impervious material built into a wall or pier to prevent moisture form moving to any part of the building. The DPC is built into base wall brickwork. It bridges brick skins and/or the brick and pier. The DPC is laid into the brick wall approximately two courses (two bricks) below the lowest timber member, typically the bearer.
- 2. WHAT IS DAMP PROOFING? Damp proofingin construction is a type 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.
