Render over DPC

[ringi]

Our render goes over the top of our DPC. 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?

If you are rendering over the dpc then you are bridging it.

using a grinder and straight edge grind out above and below dpc around 50mm then install a bell cast bead and re-render.

you cut a line in your render with the edge of your trowel where the dpc is
this then becomes a feature and seperates the render at the top of the dpc
and the bottom of the dpc by a few mil, which is enough for the dpc not to be breached by damp
