I'm about to build a new garage. It's detached from the main house, alongside an existing garage.
I'd like to match the old garage floor level, which is 2 courses below the DPC. The garage floor is at ground level at the front, at the back the ground rises very slightly to be about 30mm above the floor. In the old garage, the DPC is 2 courses up from the floor. The bricks below this are definitely damp, they look darker and have white salts on them.
As we're starting from scratch with the new garage, is there a better way? It's being built with a cavity wall, so I do have the freedom to have different levels for the inner and outer DPCs. Or there can be trays across the cavity if this is a way of doing it.
Is there a better way than just matching the existing and accepting that there will be two damp courses at the bottom of the wall? I suppose what I'm looking for really is how habitable rooms would be built in this scenario?
