Chemical Damp Proof Course
This method is both odourless and very safe to use. all our damp-proof are installed as per specification laid out under the BS6576. Dampness causes the most rapid and severe degradation of building materials and decorations. It causes unsightly spoiling of decorations, disfiguring mould growth and deterioration of plasterwork. More importantly, it is responsible for the most destructive mechanism of structural deterioration dry rot (Serpula Lacrymans).
Replastering is an important part of curing dampness. Although injecting a chemical based damp-proof course will prevent any further damp rising, the damp already present has to dry out naturally. Hygroscopic salts taken up into the brick will have contaminated the existing wall-plaster, causing staining and watermarks on the wall surface. This must be taken off and replaced with new plaster that is mixed to the correct specification to prevent the salts that are still present in the brickwork, transferring over into the new plaster-work and causing the staining to re-occur.
Application is by means of two slurry coats painted onto the bare brickwork or a render base coat, this can then be plastered over and permanent decoration can then take place within a period of a few weeks. Alternatively a Newton Membrane System can be affixed to provide a permanent barrier.
