greeno wrote:Mike, if you really wanted to put the damp proof layer on top of the slap you could just tank it with a couple of coats of black jack couldn't you?

This looks like another nice workshop. It cheers me no end to see so many good buildings going up these days.
200mm is a chunky old slab. I'd only do that if there were nearby trees, but, other than to your wallet there is no harm whatever in overdoing things here. I have a little personal thing about the cladding overhanging the brick-line in the way you propose. It doesn't bother everyone, but be warned, that overhang will be 60 plus mm. I built a house like that once, and can barely look at it these days!
With the floating floor and DPM above the slab, you'll need a good floated finish on the concrete. Is your builder aware of this? Powerfloating, if that is what you propose, has to happen when it has to happen, even if it is the middle of the night. Hand floating doesn't produce such a polished finish, but the timing can be a bit more flexible.

Any reason why you are overboarding OSB with plasterboard?
If you just want plasterboard finish them swap the OSB for a vapour barrier.

Correct Mike. Sorry, its not very clear but the dashed line is the tie-down strap.greeno wrote:Also, your DPM, you've just put it on top of the slab.

It just requires a very smooth slab, and very careful building practices, such as keeping everything very clean and free of debris.
I had considered putting the DPM between slab and hardcore but as the groundlevel finished high up the slab I thought it would be better to keep in on top of the slab. Happy to be corrected though if it wont be a problem underneath the slabgreeno wrote:What are you using for floor insulation? If it is celotex or similar it can just float.

No, it's not the end of the world, but if you can undo the screws a bit and raise the plate by an inch or so, then squeeze a circle of silicon around the screw, then so much the better.
