225-240mm below finished height.
150mm type 1
50mm block
25-40mm sharp sand.
No need for membrane under the sand, if you're going to use it then stick it under the type one and it is worth using one just because relatively speaking it costs bugger all.

Thank's for your advice , on another note would a waterproofing coating add to the lifespan of a newly laid drive or are there any downfalls of using one ?Carberry wrote:225-240mm below finished height.

It would but it is unnecessary. 150mm will support any domestic vehicles you can throw at it and light commercial so not much point in paying for removing more muck and paying for more hardcore for very little benefit.BIG BROOM wrote:Would 225mm of type 1 ( compacted ,done in two loads,ie 100mm compacted then 125mm compacted )

I aim for less sand rather than more, with a minimum of 25mm. If you pass over your sand once with the vibration plate before screeding, set the height of your blocks right then pass over them in 8 directions (up, down, left, right, both diagonals in both directions) then they won't go anywhere.
