Damp Tech are a registered damp prevention contractor, all of our damp prevention work is covered by the Biokil Crown underwritten guarantee scheme, and work to the BS6576 code of practice for the diagnosis and installation of damp-proof course.

The word rising damp sometimes can be misinterpreted in a property, our fully trained technicians will determine the difference between rising damp and other sources of dampness.

Rising damp is a common problem in older properties, this is due to the lack of an effective damp proof course or the complete omission of one.

As the water passes up the wall it evaporates away from the surface, eventually the amount of water passing into the wall is balanced by the amount which can evaporate and the water does not reach any higher up the wall. This may result in a tide mark being seen across the wall, the height of the tide can denote the amount of dampness in the ground below.

Rising damp rarely rises above the height of 1 metre above the external ground level and/or the internal solid floor level. The rising waters can carry salts into the wall from the ground, these can react with plaster or brickwork and a build up of white crystals can be seen on the surface.

Other Sources Of Dampness:

• Cracked rendering
• Porous brick or stone work
• Defective external and internal plumbing
• Condensation
• High external ground levels
• Bridging wall / floor junction
• Salts contamination
