Hi
Sorry if this has been asked before.
Basically, I want to put engineered flooring down in several rooms in my bungalow. Currently installed is carpet (hall and living room) and parquet blocks (x2 bedrooms, and dining room, and hall). The hall has carpet over parquet blocks btw, not that it probably matters. All on solid concrete floor, some of which is modern (1994) with a DPC/DPM arrangement and bone dry, some of which are 1930's and no DPM.
I intend to rip up the parquet (its pine, soft as hell, and smells of bitumen which is what its set down with).
Once the parquet is up, and the bitumen coated concrete subfloor is exposed, I plan on laying a DPM sheet, then ply to make up the level, and then floating the engineering board on that. The DPM sheet to lap up behind the skirting past DPC.
Reason for the DPM sheet is the concrete floors are old and aside from the bitumen do not have a damp proof course (1930's construction). There are minor damp areas at the wall / floor junction beneath the DPC, which is higher than the floor level (hence being damp. Beneath the DPM I intend to blackjack (or similar) to lap the bitumen up the wall to the DPC, and then DPM on top, belt and braces.
The plywood will be above the DPM, and the engineered board on top of the plywood, most likely floating.
Does this sound stupid, or reasonably OK?
Engineered is likely to be 15mm oak, in case that matters.
Thanks
Mike
