psi? pounds per square inch ? what has this got to do with concrete?
You’ll do better with 3000 psi poured four inches thick. The cost should not be much higher.
6,000 lb
# six slump
six inches thick
I would go with either 3000 or 4500, a minimum of six inches thick. Yes, this is a heavy mix, but you can park anything you want on it; a car, truck, van, boat, camper or semi…it’ll support them all. Use heavy wire mesh, too.
