Damp Proofing

Types of Damps

Rising Damp

Rising damp affects a building by rising up from ground level. Water from the ground gets absorbed through the building material, pushing all the way through the brick and mortar. The water itself is not necessarily the problem, but the salts and minerals contained in the water. These stay behind long after the water evaporates and can stain walls and absorb more humidity which increase the chances of damp and mould growth.
Typical symptons include:
– Mould on the walls
– Rot on wooden frames or floorboards
– Soaking wallpapers
– Stains on walls
– Crumbing plaster
– And many more

Penetrating Damp

Penetrating damp occurs when moisture enters a building horizontally through the wall (e.g. rain penetrates the property’s wall through masonry). Another cause of penetrating damp is through an earth retaining wall, i.e. a wall whose exterior is below the ground level such as basements or sloped buildings.
