Damp Proof Course (DPC)

A Damp Proof Course is a fast and cost-efficient form of rising damp treatment. The process involves injecting a silicone-based damp proof cream into pre-drilled boreholes in the wall where The solution then penetrates the masonry and creates a water repellent barrier.

A Damp Proof Course injection is a remedial Damp Proof Course (DPC) utilised to damp proof walls where the original DPC has failed, deteriorated or not been installed.

A DPC injection is designed to seep deep into the masonry in order to prevent moisture from the ground rising up by capillary action and causing rising damp. The cream has a consistency that allows the active component to be absorbed which creates the water repellent barrier.
