We own a 1930 house we cavity brick walls and have a few damp problems..,
Our render goes over the top of our DPC (damp proof course). The DPC is only about 1cm above the level of the paving. So I need to lower the paving (or put in a dry zone ditch between the paving and the wall) and remove the render.
However the render is very hard, so the brick gets damaged when I try to remove a test section.
Hence it is likely the brick work will need to be re-rendered over the DPC – how can this be done without bridging the DPC?
