High-Performance Damp-Proofing Treatment for Rising Damp in Masonry Walls

Dryrod Damp-Proofing Rods are a patented, high-strength rising damp treatment developed for fast, clean, and effective installation. Each rod contains a powerful silane/siloxane formulation housed in a rigid fibre cartridge, allowing direct insertion into pre-drilled holes. Once inserted, the active ingredient diffuses deep into the wall structure, creating a permanent barrier against rising damp. BBA-approved and ideal for use in brick, stone, and mortar substrates.

Key Features & Benefits

• Clean & Precise: No mess, no waste – each rod delivers a consistent dose with minimal disruption.
• High Performance: Delivers a deep, uniform silane-based barrier for long-lasting damp protection.
• Fast Installation: Pre-measured rods are quick and simple to insert with no specialist tools required.
• Versatile Application: Suitable for most masonry types, including brick, stone, and mortar joints.
• BBA Certified: Independently tested and approved for reliability and effectiveness.
