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. Key Features & Benefits Effective Rising Damp Treatment: Creates a durable chemical DPC to prevent moisture migration from the ground. Ready-to-Use Cream: No mixing required – fast, clean, and easy application with standard applicator guns. Deep Penetration: Diffuses through the mortar bed for maximum effectiveness in variable wall types. Low Odour & Non-Flammable: Safer to use in occupied or sensitive environments. Compatible with Plaster & Render Systems: Can be overcoated with appropriate renovating plasters after drying. Product Details Form: White cream Base: Silane/Siloxane formulation Packaging: 600ml foil sausage Application Tools: Suitable injection gun or applicator Coverage: Approx. 1.0 litre per 6–8 linear metres (depending on wall thickness and substrate type) Suitable Substrates: Brick, stone, blockwork, mortar Application Instructions Drill Holes: Drill horizontal holes at the recommended height and spacing, usually into the mortar bed. Inject Cream: Insert the nozzle and inject the Biodry cream evenly from the back of the hole outwards. Allow to Cure: Let the cream absorb and cure – wall drying may take several weeks depending on conditions. Replastering: Re-render using a suitable damp-resistant plaster or renovating render system. Limitations Not suitable for use in temperatures below 5°C or on frozen walls. Always follow up with appropriate plastering to complete the damp-proof system.
