There are several different methods and products used to control Rising Dampness

Chemical injection damp proof course is accepted as being the most successful, convenient and cost effective way of installing a damp-proof course where an existing system has broken down or none exists. In simple terms, the result of this operation is the formation of a water repellent, silicone based layer through the wall. This layer will chemically bond to the masonry and cannot leach out, thus providing a long-term barrier against rising damp.

Electro Osmosis is an active system introducing a very small electric current into the wall just above the ground level. The current repels rising moisture back down the wall. As long as the charge is maintained the walls will remain dry and free of damp.

Damp-proofing cream is introduced along the mortar course at regular intervals by injecting it into pre-drilled holes. The cream diffuses before curing to form a continuous water-repellent barrier.

Wall plastering as with all remedial damp proof course systems, the adequate removal and replacement of salt contaminated plaster is essential – plaster should be replaced strictly in accordance with our specification.

To correctly investigate and diagnose the causes of dampness it is important that you use the services of a trained and experienced surveyor who holds the industry standard qualification - CSRT (Certified Surveyor in Remedial Treatment).

The survey will consist of a visual inspection and testing with an electronic moisture meter, however this alone does not prove the presence of rising dampness.
Internal and external inspections will assist in proving or eliminating the sources of dampness not associated with rising damp.

Visual signs of dampness can be due to salt contamination, condensation or penetrating dampness.

At times the use of a Calcium Carbide meter will be employed – this form of testing is ‘destructive’ in that it necessitates drilling holes into the wall structure to extract samples.

Once our surveyor has determined the cause of the dampness, a full report, estimate and drawing will be submitted recommending necessary remedial works and treatments.
