Damp Proofing
Rising damp (or Salt Damp, as it is known in many parts of the world) is not the most common form of dampness encountered in buildings; this is left to condensation. However, a high proportion of older buildings are affected by rising damp to some degree or another.
 
Rising damp in buildings occurs when water from the ground rises up through the bricks and mortar of a building by a process loosely termed as "capillarity." In simple terms, the water rises up the wall of a building in the same way that oil rises up through the wick of a lamp.
 
The height to which the water will rise depends on several factors including the pore structure of the bricks and mortar and the rate of evaporation. Masonry containing a high proportion of fine pores will allow the water to rise higher than a coarse pored material.
 
Treatment of Rising Damp (known as "damp-proofing" or "damp coursing") typically involves the installation of a chemical DPC, such as Dryzone, followed by replastering using a Refurbishment Plaster or a salt retardant render incorporating Renderguard Gold. However, with the introduction of Dryzone damp-proofing cream, the process has now been simplified. The Dryzone system is based on a high-strength damp-proofing cream that is injected into holes in the masonry without the need for an injection pump.
 
Also, look at our basement waterproofing page for any basement waterproofing needs.
