Ground-floor conversions often sit on an older slab
Basement and ground-floor flat conversions common across inner London boroughs frequently have an older solid concrete subfloor laid before modern damp-proof membrane standards, which can hold residual moisture that a floor finish traps against the boards.
We run a moisture meter check on any solid or ground-floor subfloor before ordering boards, which is the single check that decides whether extra membrane work is needed before fitting can safely start.
