Dryrods deliver the correct dose every time, unlike traditional methods like cream or liquid injection which can lead to under-treatment and DPC failure. Their unique patented design ensures a consistent application of the active ingredient. Extensively tested and internationally approved, Dryrod Damp-Proofing Rods have proven to outperform competing treatment methods, even in highly-saturated walls and freezing temperatures. They are approved by the British Board of Agrement and the German WTA organization. Dryrod Damp-Proofing Rods are saturated with 100% silane/siloxane, ensuring maximum water repellency, whereas cheaper creams may only contain 25%-50% active ingredient. This pack contains 3 boxes of 10 Dryrod Damp-Proofing Rods, providing the next generation of DPC for walls, outperforming creams, gels, or liquids. It's a fast and simple DIY rising damp treatment, less messy than traditional injection methods. No specialist equipment is required; simply insert the rods into 12mm holes in the mortar lines of a building to form a powerful waterproof barrier. Each pack delivers the correct dose every time, eliminating guesswork. With coverage for a 9" wall of 3.6m, and BBA Approved, this high-performance DPC treatment is certified by the British Board of Agrément to be effective against moisture ingress for at least 20 years.
