Damp patches, damaged plaster and salt deposits near the base of an internal wall can indicate rising damp, but the cause should be assessed before treatment begins. Damplast provides DPC injection for properties in East Sheen and the wider SW14 area. Where a chemical damp proof course is suitable, cream is injected into the mortar course to form a moisture-resistant barrier in brick, stone or masonry walls. We can then advise on the reinstatement work needed to restore affected internal finishes.
