Which kind of stone is more suitable for laying a driveway

That’s a really broad question. On balance ¾ down would be adequate however how deep are you going? What traffic will be on the driveway? Do you want a decorative look and feel? If so then most likely granite. Too much ambiguity to really drill down with a proper answer.

Feel free to call the store and we can walk you through what’s needed if we have more info.
