Hi
We are in a basement flat and have had the dreaded rising and penetrating damp in our bathroom (measures 3.2m by 1.8m, so we had it totally stripped out and had a damp specialist fit Triton membrane (8mm to walls and ceiling, 20mm to floor) with a drainage channel around the base of the walls to a sump-and-pump.
We'll be wanting to fit floor tiles so need a good sound base to lay them on, but the 20mm membrane does move about a bit and has some ripples in it so will need to lay a floating floor to form a base for the tiles.
We were thinking of laying WBP ply over the membrane (we can screw direct to the concrete under the membrane using waterproofed and sealed membrane plugs) and tilebacker board on top.
Does this sound good enough, or should we fit a 100-grade polythene sheet over (or indeed under) the ply? Anything else to take into account? (All the pipework etc is going to be coming in above the floor level)
