So a concrete capping layer and 150mm - 225mm base or a much deeper sub base if no capping layer is installed, usually 500mm.
You will also need to use 80mm blocks regardless of weather they are driveline metro or not.
Good luck.
Thanks so much for your help this morning very useful info very much appreciated top man. I will post pics when all done
