The success of Dryzone inevitably produced a plethora of look-alike products. However, because Dryzone is protected by patent, none of these products can benefit from Dryzone’s unique formulation technology. Performance In fact the final Dryzone formulation met or exceeded all of the design criteria that were set at the concept stage. 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 The coverage rate will vary depending upon the roughness and absorbency of the surface, use as a guide only. Appearance 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. Dryzone Damp-Proofing Cream is the fast, clean and effective method of rising damp treatment. What Dryzone Does

Dryzone Damp-Proofing Cream is the original high performance injection cream, for the purpose of treating rising damp. It is the most rigorously tested and accredited remedial damp proofing treatment available on the market. Why Dryzone is Required Dryshield Cream is a salt resistant, breathable and water-repellent cream. It is used as a primer for Drygrip Adhesive and as a salt inhibitor on walls that have just been treated for rising damp with Dryzone Damp-Proofing Cream. Why Dryshield is Required Dryshield makes the surface it is applied to hydrophobic and weakens the crystallisation strength of the salts within, or at, the masonry surface. The surface is left breathable, so water vapour can still escape the wall, which allows it to dry out, but salts are not able to build up on the surface and contaminate, or dislodge, any part of the plasterboard. How Dryshield is AppliedIndependent tests demonstrate that Dryzone provides a more effective barrier to rising damp than competing products.

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 For heritage projects, or where replastering needs to be minimised Dryzone Renovation Plasters should be used. For Rising Damp treatment Launched in 2000, Dryzone Damp-Proofing Cream has caused a revolution in the treatment of rising damp. Dryzone is a special damp-proofing cream that is introduced along the mortar course at regular intervals by injecting it into pre-drilled holes. The Dryzone then diffuses before curing to form a continuous water-repellent barrier. This prevents the damp from rising up the wall. Since the 1950s, liquid chemical injection systems, which work in a similar way have been used to treat rising damp with a high degree of success. Active rising damp was established by submerging the bottom of the pillars in water to a depth of 25mm for a period of three weeks. At this point two of the pillars were treated with Dryzone and another two were treated using a conventional chemical treatment. A further two pillars were left untreated as controls. The pillars were kept wet for a further three weeks before being allowed to dry out for 9-months. Water was then re-introduced to the bottom of the pillars and measurements were taken to establish water uptake following treatment. The lower the water uptake, the better the formulation is at controlling rising damp.Once the Dryzone is installed, it diffuses before curing to form a water-repellent resin. This prevents the damp from rising up the wall. Replastering As the graph above shows, Dryzone’s active ingredient level is high enough to introduce as much active ingredient into the wall as the traditional liquid damp-proofing fluids which have been used since the 1950s. The amount of active ingredient introduced by the look-alike 10% cream is tiny by comparison.

Furthermore, Dryzone’s unique formulation causes these active ingredients to spread further in the wall – providing a more even and complete rising damp treatment. The difference between the spread characteristics of Dryzone and look-alike products can be illustrated using a simple spread test: Dryzone Damp-Proofing Cream is a water-based silicone cream that spreads through, and bonds with, sand;cement mortar. Any continuous sand;cement mortar line that has been properly treated with Dryzone becomes a damp-proof course. Due to the fact that it is a high strength cream, Dryzone delivers over 5 times more active ingredient to a wall, over a wider area, than other low strength competitors, making it longer lasting and more effective. How Dryzone is Applied Dryshield Cream to prime the wall: long-lasting protection against damp, salt and mould in just one coat Dryzone damp-proofing cream revolutionised the treatment of rising damp when it was launched in 2000. It was faster to install, less messy, and provided a more reliable barrier to rising damp than conventional damp-proofing systems.Eliminates the need to introduce large volumes of liquid carrier into the wall. Dryzone is over four times stronger than many competing products. Independent confirmation of the effectiveness of Dryzone came in May 2002 when Dryzone became the first damp-proofing cream to receive BBA Certification Dryzone is a special silicone based damp proof injection cream that treats and protects against rising damp. It is introduced along the mortar course at regular intervals by injecting it into pre-drilled holes. Dryzone then diffuses before curing to form a continuous water-repellent barrier, preventing rising damp and creating a damp proof course. These low levels of active ingredient are even more apparent when shown in the context of the amount of active ingredient introduced into each linear metre of wall: Flaking paint, peeling wallpaper, a “musty” odour, and timber decay are among the most common symptoms of rising damp. Failure to treat rising damp properly can result in a house that is unpleasant to live in and difficult to sell, so it is important to choose an effective method of treatment.
