hi all had some great advice on granite paving here thank you mickg.
now that i have the slabs sizes 600x900, 600x600, 300x300, 600x300 i have noticed that these are exact sizes so if i lay a 600x900 then put 2 300x300 next to it with 6mm gap they will be 6mm wider than the 600x900. i thought the 300 would have been smaller to take this into account. i brought a pack of 18.5m2. peter

would not put two 300x300 next to each other looks pants .the gaffer does random layouts for a small fee well worth it

hi cookie thanks for that. i hadnt intended putting two 300x300 together just using that as an example. i thought because i brought a patio pack they would have allowed for the gap. as it is if i put two together they wont line up. peter

You could lay it in courses with the 6x9 and 6x6 in one course and 6x3 and 3x3 in the other, have done this with sawn sandstone and it looks fine.
If you particularly want random then you either have to trim 1 or 2 edges of the 6x3 and 3x3 before laying, I would suggest a bench/table masonry saw for this.
The other way, which I have used is to lay the two 300mm tight so that they keep to the size of the 600mm. When the mortar has set, saw the joint with a 230mm disc cutter.
The disc follows the joint giving a near perfect cut, just beware when approaching the end of the joint that you don't score the adjacent slab.
It's a pain that they will not manufacture the slabs so they fit with a joint, if they cut the 300mm side at 297'ish, happy days.

Its a very good point
we have our granite manufactured in the following sizes:-
600x900
600x600
600x295
295x295
This as you point out allows for a joint without pulling your hair out..
