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.
The Dryzone 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 video below demonstrates how Dryzone damp-proofing cream is used to treat rising damp (includes audio commentary):
Quick to install
Up to 3 times faster than standard damp-proofing injection systems.
Simple to install
Less scope for operator error
Eliminates the need to introduce large volumes of liquid carrier into the wall. Dryzone is over four times stronger than many competing products.
Non-caustic, non-flammable, not injected under pressure.
Does not contain white spirit or iso-paraffins.
Spillage & mess virtually eliminated
No problems with damp-proofing fluid leaking into neighbouring rooms or properties.
No electric DPC pump required
Can be used in situations where power is not available.
Independent tests demonstrate that Dryzone provides a more effective barrier to rising damp than competing products.
Full instructions for installing Dryzone damp-proofing cream can be found in the Dryzone datasheet which can be downloaded from this page. For those requiring more detail, a 19-page guide to "Rising Damp and its Control" can also be downloaded.
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

The report was carried out by the University of Portsmouth and published in February 2008.
