Damp Proofing

A basic guide to the types of damp.

Rising Damp

Rising damp is very simply where masonry acts like a sponge to water content residing in the ground. Before 1930 damp courses were virtually non existant or not effective in tackling this, so water can literall be sucked up from the ground by capilliary action til gravity takes hold. This is ususally between 1m and 1.2 metres above ground level. Click here to learn more.

Penetrating Damp

Penetrating damp is where water permeates through the masonry of a building. Most commonly solid walled buildings (period buildings) suffer most with this as the only protection is the exterior paintwork, a cavity wall can suffer a breach if its cavity filled with debris or where the wall ties are allowing water to track through to the inner leaf of the building Click here to learn more.

Condensation

Condensation is the most common call out we attend. Condensation is caused by warm moist air hitting cold walls or ceilings. The consdensation process therefore happens where the air meets the walls. This is usually because the building has poor ventilation, poor insulation or both. Click here to learn more.

Leaks and Trapping

Leaks from plumbing, roofs and blocked gutters can get into walls and floors, this can stay there during the course of a whole winter and can take months to dry out. In addition, where a leak has damaged walls it is usual to decorate over and stain block the area, but this is known as trapping as the moisture will have nowhere to vent out to cure the moisture problem.
