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.
