I'm laying down a plastic sheet for damp proofing in a basement then putting a concrete slab on top. What's the minimum thickness I need to give for the slab? (I want to conserve ceiling height.) 80mm Polyfoam insulation and 70mm screed will go on top so it's all going to add up.

100mm is fairly typical.
