A damp proof course ( DPC ) is a physical barrier inserted into the fabric of a building to stop water passing from one place to another. This can be on a horizontal plane, stopping water rising up from the ground by being sucked up by the dry masonry above, or vertically to stop water passing from the outside of a building, though the masonry, to the inside.

Damp Proof Courses or Damp prevention has taken many forms through the ages and one of the earliest forms was to use a layer of slate in the construction as a impermeable material between the brick courses just above ground level to prevent upward transference of moisture through the walls. This process was used right up until the early 20th in building construction only being replaced with plastic alternatives which is now commonplace.

Prevention of Rising Damp

Rising Damp or Salt Damp as it is known in many parts of the World is second to Condensation which is the most common problem of dampness encountered within buildings. However, a high proportion of older buildings are affected by rising damp to some degree or another, as shown in the graph below:

The height to which the water will rise depends on several factors including 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

Treatment of rising damp (known as "damp-proofing" or "dampcoursing") typically involves the installation of a chemical DPC, using specialist injection equipment, followed by replastering using a salt retardant additive such as Renderguard Gold however, with the introduction of Dryzone Damp – Proof Cream, the process has now been simplified.
