How Many Slabs

[ALFDEK]

I have an area of 14.5 sqm to slab. I have 3 sizes of slab. (560x845, 560x560 and 560x410) what is the best pattern/lay out for these.

What's the shape of the area?

[kvalidir]

Can you give us a number x number area to work from please, and as Jim Says a shape would be handy?

Whatever you find prettiest. All the same colour ?

The 845 and 410 have little in common with 560 so may be difficult to fit into a repeating pattern. Get a sheet of graph paper to draw a scaled plan onto, and experiment. Maybe the you can create lines of different widths width using one of the sizes at a time.

You don't say what shape the 14.5sq mtr patio is. ie. is it 7mtrs X 2.07 mtrs or 4mtrs X 3.62mtrs. Also looking at the sizes you have given they look like raj sandstone or something like. They are usually laid in a random pattern you supplier will advise you and there are calculators available on line to help you get the numbers of each right. Tip, if they are indeed the sandstone riven you must lay them on a wet slump. Do not dot and dab. The mortar will show through the stones Sandstone is porous.

Of course, if it is random you can always overcome trying to fit everything by breaking/cutting a larger slab to fit an awkward remaining space.

Just realised. The title asks how many, but the description says you have the slabs and are just interested in the pattern. Which is it ?

Here you go Alf. Huws Grey sell that size stones in a pack. there is a 7.2sq mtr pack with the stones already chosen and in the correct numbers for random laying. 2 packs and you are home and hosed.
This pack has 6of 900X600, 6 of 600X600 6 of 600X300 and 5 of 300X300.

Sorry , the area is rectangular and is 5m x 2.9m

Another tip, the sizes that Alf quoted are taken to be 600X900, 600X600, and 600X450 for calculating numbers required. When they are laid with the correct spacing that is the cover that the stones will give.

Looks like you will need 12 of each size.
