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.
In-house and independent tests demonstrate that Dryzone is considerably more effective than look-alike products at controlling rising damp. This is not surprising when you consider that Dryzone contains over 60% active ingredient (active silicones) whereas many look-alike products contain as little as 10% active ingredient.
