What is damp proofing and DPC?
Chemical damp proofing is at its simplest a method to prevent walls from acting like a sponge by drawing water up from the ground - a process known as rising damp. Modern buildings are constructed with a tough Damp Proof Course (DPC) sandwiched between the bricks all around the house just above the foundations.
This damp proofing course forms a barrier, preventing damp from rising up the walls. Unfortunately, however, many older buildings did not have a DPC applied during their construction or the materials originally used have broken down. In either case this allows dampness to penetrate through.
Chemical Damp Proofing Course
This is where a Chemical DPC comes in. In simple terms bore holes are drilled into the wall and a chemical fluid is pumped in which reacts with the moisture to form a permanent water barrier.
