This one Mike
Here we go chaps, here's another version.
Mike - How does this look to you? I have left a 10mm gap between the top of ground slab and the 100mm insulation just to show the DPM route but in reality this would sit directly on top of slab (thus bringing the FFL level 10mm lower down too).
Is it okay to have the ground slab level with the top of the footings?
Is it okay to have the finished floor slab at 75mm or need to be thicker?
Assumptions would be that I would use some kind of tanking paint against the outside face of the inner block skin, then dim outside that tucked into the DPC.
The green line is another layer of DPM/Tanking paint that could be applied to the outset skin, below ground level, if it was thought necessary…or would this potentially cause issues allowing the bricks to breathe?
Doing it this way gets me to 360mm below ground level, at which point I could put in a 6" deep false floor for running ducting under bringing the final floor height to 8" below ground level. What do you think?
Cheers
Mark
