Hi, i am required a 4 inch deep concrete base before i can have a concrete garage erected. I have a tarmac driveway which is reasonably level and i was wondering it i could put a concrete base directly on top of the tarmac?
I was thinking of placing the correct size shuttering directly on top of the tarmac making sure its level and square. Then put some sand down inside the shuttering followed by a sheet of polythene followed by the concrete, leveling off and tampering down.
Would this be ok?
Cheers
