Dryrod Damp-Proofing Rods

What is Dryrod?

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 Agrement.

Why Dryrod is Required

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.

What Dryrod Does

The active ingredient contained within the rods spreads through, and bonds with, sand;cement mortar. Any continuous mortar line that has been properly treated with Dryrod Damp-Proofing Rods becomes a damp-proof course. Due to the unique formulation of active ingredient allowed by the design of the rods, a Dryrod treatment is over 4 times more effective than the next best treatment method.

How Dryrod is Applied

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.
