Would appreciate guidance on a subject I know little about...
I intend to have sheet vinyl laid over both new and existing floors. The new floor, which abuts the old, is floating concrete screed (should be sufficiently dry by end December). The old floor was sheet vinyl (now removed) over quarry tiles with a few old concrete patches. I've scrapped off remnants and cleaned the old quarry tiled/concrete floor and can see that the floor is quite uneven (+ or - 10mm at a guess). Also, I believe there is no damp proofing beneath the tiles or old concrete patches. The old, original tiled floor (circa. 1958) is set onto concrete screed straight onto hardcore & earth.
Question is: what's the best "belt-and-braces" floor preparation for my circumstances?
Something like this perhaps?

And what trades-person would do such work? I'm wary of having the sheet vinyl laid by a high street chain who don't give much thought to the best solution but simply skim over with latex self-levelling compound (because that's what they always do) - or am I doing them a dis-service?
Thanks in anticipation.
