Rising dampness occurs when water enters a building through capillary action.

Rising dampness is commonly encountered in many buildings but is also often miss-diagnosed.

Water rising from the ground into a building will often introduce salts into the walls and plaster coats, which over time can become highly concentrated on the surface.

Treatment of rising dampness involves:

  • Reinstatement of a damp proof course (usually chemical, by way of injection into the masonry)
  • Removal of affected plaster
  • Reinstatement of affected plaster incorporating a salt inhibitor and a waterproof additive
