In the case of drill holes becoming blocked these should be re-drilled just prior to injection or a new hole should be drilled nearby to ensure that an adequate volume of DampSolve is introduced. Where traditional pressure injection fluid cannot be used, Dri-Wall DPC Injection Kit is the answer.

Using a large caulking gun to inject the cream into the wall the cream will provide an effective barrier against rising damp in walls. The graph across shows the performance of high-strength DPC cream in a typical lime mortar compared with a low-strength DPC cream. This is introduced along the mortar course of the damp wall at regular intervals by injecting it into pre-drilled holes.Dryzone Damp-Proofing Cream is a water-based silicone cream that spreads through, and bonds with, sand;cement mortar.
