A damp proof course helps stop ground moisture from moving upwards through masonry by capillary action. Where an existing course is absent or no longer effective, Damplast can investigate signs associated with rising damp in Mortlake and install a chemical DPC. Silicone-based or chemical damp proofing cream is injected into suitable brick, stone, or masonry walls to create a moisture-resistant barrier. We can also restore affected wall finishes after the damp treatment.
