Tolernace of paving flags

[rks]

just laying indian sandstone riven but calibrated , finding some are for example at least 10mm longer or wider , how does one accommodate such a big variance when laying when gap between is normally around 10mm , would it be ok to trim down some of these and if so would i need to cut at same angle /camber ? sizes im using are 275x275, 275x560,560x560 and 560x845
thanks

Lay them tight if stuck and then grind out the joints to match. Try to let the gringer wander a little to avoid a poker straight edge. Absolutely dont worry about trying to cut a reverse camber like the flags have, its unneccesary and could be quite dangerous.

okay thanks for that , I think I will have to remove 1 of the larger slabs , been laid for 2 days now as gap will be much larger if I don't remove it , so i'll do as you suggested .

Are you saying the flags are out of plan size tolerance (should be within ± 3mm) or is it the joint widths that are causing you problems?

If the flags are oversize, get on to the supplier, but if it’s the joint widths, there’s a page dealing with joint balancing
