Dryzone works by creating a new, effective damp-proof course (DPC) that prevents rising damp. It's a silicone-based cream that's applied to masonry to create a hydrophobic barrier.
Here's a breakdown of how it functions:
- Application: Dryzone is injected into a series of holes drilled into the mortar bed of the wall, typically around 150mm above ground level.
- Diffusion: The cream then diffuses into the pores of the bricks and mortar. This diffusion process is key to its effectiveness.
- Hydrophobic Barrier Formation: Once in place, Dryzone creates a hydrophobic (water-repelling) barrier. This barrier prevents groundwater from rising up through the wall via capillary action. This capillary action is the mechanism behind rising damp.
- Stopping Rising Damp: By blocking capillary action, Dryzone effectively stops rising damp from occurring above the treated area. The water can no longer travel upwards through the masonry.
In essence, Dryzone provides a chemical DPC that's designed to be more effective and easier to install than traditional methods. Its silicone-based composition allows it to penetrate the masonry and create a lasting barrier against moisture.
