Hi,
I am buying a new build house and the snagging surveyor has raised an issue with some floor levels in a bedroom and 2 en-suite shower rooms, which are out of NHBC tolerance.
The main issue is with a tiled floor that is off by 6mm over 2 metres. The build states that it is in tolerance.
NHBC state..
9.1.7 Ceramic, concrete, terrazzo and similar tile finishes
.”the variation in surface level should be within ±3mm measured using a 2m straight edge with equal offsets”
Does that mean 3mm over 2 metres or 3mm per metre , so 6mm over 2 metres?
NHBC state for other floors...
level within a 3mm deviation per 1m for floors up to 6m across
Strange that they would publish the same tolerance for both when sloping tiled floors in bathrooms is more of a safety risk.
Thanks
