Dry-rod – damp proofing

• Even more effective than Dryzone Damp-Proofing Cream
• No spillage or wastage due to patented rod design, a full treatment is achieved every time
• Available in foil packs of 10 rods or boxes of 50 rods

Dryrod Damp-Proofing Rods are the latest innovation in rising damp treatments. They are patented 12mm diameter grooved fibre rods that carry a powerful water repellent material. Dryrod has been thoroughly tested and is independently approved by the British Board of Agreement.

Rising damp is the phenomenon where groundwater rises up through a wall via capillary action. Capillary action is the ability of a liquid to flow along narrow spaces, counter to the forces of gravity. Bricks and mortar can be very porous and contain many fine capillaries, through which water can rise. The groundwater that rises up through the wall often contains salts that can contaminate plaster and cause lasting decorative spoilage.

Most modern properties are built with a damp-proof course. Some properties, however, were built with no damp proof course, or the original DPC has failed, meaning that rising damp occurs and it is necessary to make remedial repairs. Older pressure injection techniques for treating rising damp are time consuming, complicated and expensive. Dryrod Damp-Proofing Rods are quick, easy to install and highly effective.

Holes are drilled in a wall, using a 12mm drill bit, along the first continuous mortar course that is at least 150mm above ground level. On a standard brick wall, these holes are drilled 90% into the width the wall at 120mm intervals.

Once the holes have been drilled, the rods are inserted by hand. Once they are inserted, the carrier rods slowly diffuse water repellent deep into the damp masonry, curing to form a powerful barrier to further damp ingress. No fuss, no mess, no stress.
