Has anyone any experience of using a product from a company called Dryzone
for damproofing brickwork. Its a cream thats injected into holes drilled in
the mortar bed. Injection is by means of simple hand operated gun like
silicon sealant guns and its easy to see when sufficient cream is in place..
The company claims that the waterproof bit of the injection seeps gradually
along the mortar bed and seals it against damp. It appears a lot easier to
use for the DIY man than the usual silicone based fluids which need fairly
high pressures and drilling of brick faces, and are messy. Employees of
Dryzone do not need to reply.
