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.
