Replacing a Damp Proof Course
Manual and physical replacement of a damp proof course is often necessary where chemical injection techniques have failed or are inappropriate.
This listed building required 5 metres of Damp Proof Course replacement.
Each section of approximately 700 mm per stage was removed, the lower course cleaned and dressed, then new mortar, DPC and bricks replaced in situ.
Here you can see the process in more detail. This particular job was made problematic by the fact that the damp course in this instance ran across a chimney breast. The section of chimney base needed some rebuilding and contained extensive amounts of debris, which required careful and painstaking removal through a small aperture.
