In this case, the client was experiencing damp and water penetrating from the exterior of the building. To rectify this, we hacked off the old, exisiting porous rendering and re-applied two coats of waterproof sand cement. We also drilled a DPC using Sovereign Chemicals damp proof cream for added security.

The image below shows the before and after images, although the first image is after we hacked off - we were too eager to get started we forgot to take a picture until this point!
