whats the best way to lay riven pving with a 2 inch gap to be filled with gravel. what would the sub base be?

[Stuarty]

Sub base would be atleast 75mm MOT type 1. Im not sure on having a 2 inch gap to put gravel in it though, if it comes out of the gaps you will more than likely end up on your arse!

[lutonlagerlout]

is the 2" gap around every slab???
are you going for a decorative look?
if so the slabs need to be well stuck down
let us know

[peter meddes]

yes the 2 inch gap is around all the stones

[lutonlagerlout]

you need 100mm of compacted hardcore,followed by 50mm of wetmix,gritsand and cement
remember to haunch the bed up the slabs to hold them in position
i would also use unibond or similar in the mix to add adhesion

This is a very popular way of laying slabs in low traffic decorative garden areas in South Africa, if you look at Revelstone.co.za or Smartstone.co.za (no vested intersest) you will see examples and the stone chip is swept in loose, or lawn is grown between the gaps. The slabs themselves are on a 100mm subbase and 50mm compacted sand. I know this sounds too loose but thats what they do. Revelstone might have full laying instructions, Iknow they do have a pamphlet that they would post.
