Rising Damp Repair
Moisture from the ground travelling upward through the pores of masonry walls via capillary action. It is characterised by a tide mark on the internal plaster at around 1 m, damp patches, peeling wallpaper, and salt staining. The primary remedy is to inject a chemical damp-proof course into the base of the wall and re-plaster using salt-resistant render. Rising damp is sometimes confused with condensation or penetrating damp, so an independent survey is advisable before committing to treatment.
