Rising damp is the process of water rising vertically up from the ground and travelling by capillary action through porous material such as bricks and mortar. This will cause the wall to become damp as hygroscopic salts travel into the brickwork and plaster. As water evaporates, it these salts that are deposited into the wall attracting more moisture from the atmosphere.
As the process continues, the wall and surrounding area becomes more saturated and signs of rising damp will become evident such as crumbling of plaster and white tide marks appearing on a wall up to a height of around 1 metre.
Problems such as dry rot, wet rot and wood boring beetle infestations are also more likely to occur as surrounding timbers become saturated. It is a slow process and can be present for many years before any sign of a problem appears.
Rising damp occurs due to:
Rising damp will only appear at ground level. Signs include:
Our survey assessment will decide the best course of action which will involve the elimination of all sources of the damp and moisture. This could involve clearing overgrown vegetation, to fixing a leaking pipe. In certain circumstances the application of a damp proofing system and removing plaster that has become affected by moisture is unavoidable.
Our goal is to provide the right solutions that provide the best long term protection for the property.
