I have a garage floor that slopes frome back to front ( about one brick course over 6m. since I am not putting underfloor heating in, can I just put down the DPM then lay the insulation (100mm polystyrene) then make up the difference with the concrete (110mm at the shallower end). Or do I have to level first before the DPM. I,m bringing it up to floor level to extend the kitchen into it.
