What is Penetrating & Lateral Damp?

​

Penetrating and lateral damp is a common form of damp in buildings. It can occur through walls & roofs, or through openings (e.g. window reveals, light fittings, pipes, cables etc) and through the underground walls of basements and cellars.

​

Water typically penetrates the outer skin of a building and then appears inside.

​

Penetrating damp is most often associated with single-skin walls, but can also occur through cavity walls such as tracking across wall ties.

​

What Causes Penetrating and Lateral Damp?

​

Cracks in render and masonry provide a pathway for damp to penetrate. The primary cause of rain penetration through walls is defects in the masonry such as porous masonry (i.e. under-fired bricks, porous stone, or porous mortar).

Our Solution:

​

We pinpoint the exact source of penetration, using specialized damp meters, and then take the appropriate action to stop further ingress and do remedial repairs to areas that suffered damage.
