We built up to DPC with 100mm blocks, laid down the DPM, and had the concrete slab poured. I am now going to lay 100mm blocks on top of the DPM and need some guidance on how I should proceed.
1. Should I mortar underneath the DPM, or just above it ?
2. How thick does the mortar bed need to be when laying the blocks on top of it ?
3. How should I deal with the creases in the DPM ?
