[QUOTE="alabama, post: 821832, member: 2218"] So all you need is a slab that heavy equipment can operate on. Not too hard to do. The most important thing is a good tight compaction on the soil. An easy way to check that is to “proof roll it” That is take a loaded dump truck and drive it back and forth across it and check for pumping. Pumping? You will know it when you see it. Just watch the soil under the tires and if it moves up down under load and springs back up it is pumping. If your soil is well compacted most any thickness of concrete will work but to be safe use 5 inch. It is a lot cheaper to buy concrete now than patching later. I would thicken it along the edges a little. Reinforcement: number 4 bars at one foot spacing both ways mid slab will be fine. If it fails from equipment load it will be short span flexure but most likely shear, so placement is not a big deal. You could get away with 6 inch by 6 inch 10 gauge welded wire if your soil is “very well” compacted and not saturated while you are working on it. But I would feel much better with a rebar mat. Fiber reinforcement: I have never liked it and tell most folks it is a waste of money. There is no substitute for steel. Use 3,000 PSI concrete and keep it wet for a week or two while it cures. Place plastic under it if for no other reason than to keep the water from seeping out of the concrete while it cures. You don’t want concrete to dry and shrink. You want it to hydrate and cure.
