Hello all,
I'm turning an old pantry into a shower room for my mum. it is roughly 1.8m x 1.2m
I have taken up the old quarry tiles (laid on sand) and excavated two bricks down from previous floor level at a depth of 150mm - the injected dpc on the outside is in the first brick down.
I want to put in a concrete floor in the following order:
1. concrete 80mm
2. DPM
3. 25mm floor insulation
4. 12mm marine plywood
leaving me with 30mm to put the flooring in to bring it up to the previous floor level.
However - does the DPM lap into the mortar beneath the first brick down, or above it?
