New rising damp treatment from the makers of Dryzone damp proofing cream. The damp proofing rods form a damp proof course by distributing water repellent material along the mortar course. BBA approved, Dryrod is the most effective form of rising damp treatment available, proven to work even on highly saturated walls (up to 95% saturation). Dryrods provide a more effective chemical damp course than traditional dpc injection creams and are extremely easy to install, making them a great DIY rising damp treatment. You can reduce the cost of rising damp treatment by avoiding getting someone in to install an dpc injection with specialist equipment.
