I am getting one of those concrete sheds what come in slab form. It is going to be 10ft x 21 ft. I have to put a concrete base down first and the company will put it up then. Any done one of these, how deep does the concrete base have to be 12 inches or 6 inches ?
What cost am I looking at on average for the base ?
Thanks in advance
