Damp Proofing Guides
Damp proofing prevents groundwater and moisture entering buildings through walls and floors. A damp proof course (DPC) is a horizontal barrier in walls, typically at 150mm above ground level. Internal treatments manage moisture where external work is impractical. These guides explain how damp proofing works, when it's needed, and which method suits your situation.
Damp Course Explained: What is a DPC and How Does it Work?
Complete guide to damp proof courses: what they are, how they prevent rising damp, Building Regulations requirements, and the difference between DPC and DPM.
