bridged dpc

Hi chaps.

Kind of plastering kind of building question so opted for building.

Got an old extension with a damp problem to sort. It's currently been rendered down to ground level, has no dpc as it was originally the coal shed or loo.

We're going to knock off the old render which will obviously make a mess of the brick faces, inject a dryzone dpc and re-render.

So as the brickwork will need covering we were thinking about breaking the render at our injected mortar line with maybe an expansion bead or back to back stops with mastic.

Anyone dealt with this before? Cheers.

Bump. Ta

Yeah sounds about right to me. Dont render over the new damp course. Set your bead just above it. Your render finish near the damp course should flare out 20-25mm to form a drip. So as water running down your render, when it rains, will drip from the flared out render on to the ground. Rather than onto the brickwork.
