If a building does not have any form of damp proofing this can mean that, over time, water may start to rise up from the ground and up through the walls. If this is left it can cause damp spots and lead to mould, and further damage to the building.

Damp Proof Course (DPC) is a layer of waterproof material, that is applied in to the walls of a building, near the ground. This is used to prevent any rising damp, preventing mould and fungal residue, and reducing the risk of damage to the building.
