I need to replace an expanse of old tarmac, concrete and crazy paving with something that will look acceptable in a domestic environment and which will be ok to run cars and delivery vans over (as happens now). The existing is broke up and sunken in a number of places. Block paving has been suggested by a local builder. He says 2 inch of hardcore + concrete block paving on sand will be fine for a drive. Given the existing sinking, I'm distinctly dubious. I don't want to end up with something that pools rain water where the car is parked after a couple of months.
Any golden rules for this sort of thing please?
