Launched in 2000, Dryzone damp-proofing cream has caused a revolution in the treatment of rising damp.
The patented Dryzone system now outsells our traditional chemical injection damp-proofing treatments and is the best-selling rising damp treatment on the UK market.
Damp-proofing cream is introduced into a series of 12mm holes drilled into the mortar course by means of a simple applicator gun. Once the Dryzone is installed, it diffuses before curing to form a water-repellent resin. This prevents the damp from rising up the wall.
The Importance of Effective Damp-Proofing
Naturally, homeowners want the most effective products available to be used to treat rising damp in their properties. Creating the best possible barrier to rising damp minimises moisture in the wall, blocks the build-up of ground salts, and reduces heat-loss.
For this reason, Dryzone has been formulated to form an effective damp-proof course in walls of all types and has been tested under more conditions than any other rising damp treatment on the market.
This is important because no two walls suffering from rising damp are the same. In particular the physical properties of the mortar used to construct walls can vary considerably and this can have a significant influence on the effectiveness of any rising damp treatment.
The effectiveness of Dryzone has been verified under a wide range of test conditions by independent test houses around the world. Test conditions examined include:
- Saturated walls (up to 95% saturation)
- Low alkalinity mortar
- High alkalinity mortar
- Low porosity mortar
- High porosity mortar
- Lime-based mortar
- Cement-based mortar
As with all remedial damp-proofing systems, it will be necessary to remove and replace any salt-contaminated plaster. The introduction of our plasterboard-based Dryzone System replastering method has greatly simplified this process.
Dryzone is not suitable for application to walls as a treatment for penetrating damp.
