im going 5"deep with metal gridding and damp proof membrane.
its only going to have cars in there nothing heavy
better to put it in, dig soil out and put 150mm type 1 or similar. get it whacked down and blind the type 1 with whin dust, this will stop any sharp edges of the hardcore puncturing the polythene membrane as you lay the concrete base.
your only goin to do it once so better to do it right mate
