Damp courses, also known as DPCs (damp proof courses), are an important element of building construction. They help to prevent damp, mould and fungus from penetrating walls and floors in homes and buildings. For instance, damp proofing materials like plastic and bituminous felt are common damp course options. Furthermore, waterproofing agents and membranes are also used to prevent the penetration of moisture in the form of liquid or vapour. Other synonyms for damp course include damp barrier, damp membrane, waterproof membrane, damp shield, and many more. These synonyms refer to the same critical component that protects your home from water intrusion and damage.
