Driveway - 20mm Granite Slabs

[Sidonio Costa]

Hi All, will it be a good idea to use 20mm granite slabs for a driveway, considering that it has already got a solid concrete ( and reinforced) base, probably around 7 to 10 inch?

Kind Regards

Should be ok if quality slabs and on a solid bed.

Seek the manufacture/suppliers' confirmation.

I'm concerned if I don't use a good tile adhesive, the slabs will come loose with the weight of the cars.

They won't if you use a slurry primer on tiles, and better to use a primer on concrete too.
