How to deal with grout gap of Indian stone

[markyyyyyy]

Just doing a dry lay of Indian stone before putting on the mortar bed, starting tomorrow

The issue i have is with the size of the grout gap alongside the large slab (bottom left)

It’s as if the 600mmx600mm slab above it is slightly too wide.

What to do in this situation?

Do I install it on a mortar bed and once set, trim the slab down to ensure the grout gap is 15mm across the length? Currently the width of the grout gap is 20mm (alongside the largest slab) due to the discrepancy and 15mm alongside the 600mm slab.

I want to keep the paving butted up to the edging on the left so I don’t want to move the slab across otherwise it would look odd

Don't start trimming slabs. Have a bigger joint, where two smaller units exceeds that if the bigger unit. Close the gaps slightly on the others.

Cheers. So in this case would you move the big slab to the right by a few mm (not ideal) or move the 600x600 slab left slightly to reduce gap between the 300x300 and 600x600?

Didn't you ask this question in the "how wide are joints" thread? There's so many I loose track.

If you wanted perfect, even joints, then you should have chosen a slab that is perfectly square and evenly sized.

With these slabs the joints vary to accommodate the natural uneven unit sizes. That's the way it is.

Gaps will vary from around 10-25mm , once finished will look fine .

Probably yes. Do you really have enough time on your hands to go back checking what people ask in previous threads ?

Thanks anyway

It’s my first time laying Indian stone and a project like this

I try for something like 15mm gap, usually have to cut the small ones down slightly, to get everything even.

once down, I sometimes go around with grinder to correct any non-parallel tiles.

No, but deja-vu hits me like a pallet of slabs
