Many older properties suffering from the adverse effects of rising damp – particularly those with national heritage importance – can be rectified using the physical damp proofing system from Dampcoursing.

When chemical dpcs are used, they call for the removal of old plaster, and the application of a specialist plaster that is an integral part of the chemical system. However, with buildings of historic importance, the removal of the old plaster is often not an option, and in such situations physical dpcs will bring the perfect solution.

Working from both sides of the wall, highly trained operatives cut through the walls using specialist equipment – creating a slot cut wide enough to receive the new dpc, mortar bedding, and packing. This operation is carried out in short lengths, ensuring the structural stability of the building throughout the operation.

The mortar course is then repointing the entire length of the work to create a finished job that is neat and tidy, without adversely affecting the traditional look of the building.

This method of damp proofing is suitable for walls where existing damp courses have failed, or for walls that never had a dpc – whether they be of brick or stone construction, or a combination of the two.

Wall thicknesses of up to 1m can be accommodated. Should the wall be of random course stone construction, Dampcoursing is technically able to overcome any problems that might arise and successfully install a physical damp course.

The real benefit of this method of refurbishment is the elimination of any need for removal and making-good of any plasterwork on the internal wall faces.
