Hi there,
I want to put in an indian sandstone driveway, but I'm worried that the weight of a car could cause the stones to break. Are there thicker stones than the samples I've seen in the stores? or do I need to change the base that is under the stones? any help would be greatly appreciated. Thanks!

You can use sandstone flags for a driveway but best to stick to the darker ones they're stronger and don't show the tyre marks so much. You need to lay the flags on 100mm of concrete/screed possibly with an sbr bondbridge too. It used to be easier to do than it is now because the flags tended to be thicker but now they're a lot thinner so they can save on shipping. The base under the bedding needs to be 100-150mm of well compacted type 1.

In the past Indian sandstone has always been 25-40mm thick. However the current trend has moved towards 22mm calibrated as Pablo says. 22mm is pushing your luck for a driveway. Also need to consider that the technical spec will actually be 22mm +/-2mm. This means that some slabs may be as low as 20mm thick with the occasional real thin one thrown in there.
Try and find a supplier with some thicker stone. I have PM'd you with some info

not hijacking you steve but stone block paving is available
the smaller units IMHO should guarantee a greater success for a driveway
maybe something for you to look into on your trip LSP
IIRC about 40-45 per m2 +VAT

They look nice, are they riven and tumbled?
Bit overpriced IMO though.

Think there
Calibrated underside
Sawn edge
Natural top
Tumbled
But Danstan is user of this site so I am sure he will tell me if I am wrong.

were they accurate enough to lay as standard block paving cookie?
I imagine the labour cost of laying them as setts would be considerably higher than doing them as for block paving
I like the look of these sanstone block paviours

So they haven't got nibs.
Does that mean you can Wacker them down in the normal fashion, or do they move without the nibs?
Who sells them?

What method did you use in your picture as the gaps look bigger and you say you used gunpoint.

Hi
All explained here:-
http://www.pavingexpert.com/blocks_stone01.htm
These are sandstone pavers designed to lay the same as concrete pavers - interlocking. NO pointed joint.
My brother laid this one (one of the first to be laid in the UK)
Made a big impact on the market about 4 / 5 years ago and is still sold and developing through a network of suppliers and stockists, including ourselves. Not cheap but not everybody wants cheap.
