Whenever Rising Damp is diagnosed, it is important to have the condition correctly treated, as failure to do so can cause damage and devaluation to any property. It is not sufficient to simply cover up the problem with a special paint or coating in the hope that the problem will go away. Only by preventing the dampness rising up the wall in the first place can rising dampness be adequately controlled.
Up until now, the most widely employed method of achieving this has been to inject water-repellent fluids into the wall under pressure. Although this method has proven to be effective, it is known to have a number of disadvantages; for example, it introduces large amounts of liquid carrier into the wall, prolonging the drying out period. The process is also very slow and operator dependent.
Dryzone is a revolutionary new material for the control of rising damp. Dryzone comes in the form of a water-repellent cream packed in a 600ml foil cartridge to minimise environmental impact. The Dryzone cream is introduced by means of a simple applicator gun into a series of holes drilled into the mortar course. Once the Dryzone is installed, it uses the moisture contained in the damp wall to diffuse where it is most needed before curing to form a water repellent resin.
Dryzone is the result of an extensive in-house research and development programme. This involved the screening and testing of hundreds of potential formulations. These tests demonstrate that Dryzone offers a higher degree of protection against rising damp than the chemical injection systems that it was designed to replace. A paper describing the development of Dryzone was recently presented to the Property Care Association (PCA) convention.
