Rising Damp

Rising damp is a relatively rare form of damp that affects the walls of buildings. It occurs when moisture from the ground travels up through the walls by capillary action. This means that ground water is effectively sucked up via the mortar joints. This water contains salts that also travel up through the wall.

Generally rising damp is first noticed by the damage it causes to the internal walls of a building. Plaster and paint can deteriorate and any wallpaper tends to loosen. A visible stain often appears on the wall in the form of a tide mark at the point where the ground water has reached. It also possible that  salts may be seen blooming on the internal surfaces.This is something often associated with rising damp and will lead to the de bonding of paints and even plaster work. Externally, mortar may crumble and white salt stains may appear on the walls.
