Dampness in buildings can lead to structural deterioration, decay of timber, spoiled decorations and health problems through the development of moulds and mites. Absorbent materials such as paper, wood, cloth or brick absorb moisture from damp air, and their moisture content changes with humidity.
A wet wall will consistently lose moisture to the air through evaporation, but constant water rising through the masonry causes damp patches, salt marks and associated mould and fungal growth, typically due to the absence, failure or bridging of the damp proof course.
Rising damp comes from wet soil, which contains nitrate, chloride and sulphate salts. These rise through the masonry and are left behind as water evaporates, and over time rising damp can cause high levels of hygroscopic salts in masonry.
We use Protimeter equipment to test for damp and salts in masonry, as well as providing laboratory analysis.
The damp proof course is renewed using BBA approved remedial damp proofing products, after which the plaster is removed and replaced with specialist renovating plaster and damp proofing and waterproofing additives to ensure hygroscopic salts are removed.
