Effective Chemical DPC for Treating Rising Damp in Masonry Walls
Biodry DPC Damp Proof Injection Cream is a high-performance, silane/siloxane-based formulation designed to create an effective chemical damp-proof course in brick, stone, and mortar substrates. Supplied in an easy-to-apply 600ml foil sausage, it diffuses deep into masonry to form a long-lasting water-repellent barrier that stops rising damp in its tracks. Ideal for both renovation and remedial damp-proofing applications in domestic, commercial, and heritage properties.
