How thick should a small concrete slab be?

How much does a 40×60 concrete slab cost? It would be about $8,500 to $12,000 for a 40×60 foot concrete slab, 6 inches thick. That's based on national averages of around $5 per square foot for a fully engineered, finished concrete slab, including labor and materials.

You do not need rebar for any slab if you make it thick enough and space the joints properly. Rebar in jointed pavement is there to counter the cupping effect of thermal expansion. I always recommend the use of rebar or at least rewire. Any concrete slab can crack.

As for thickness, non-reinforced pavement four inches thick is standard for passenger car driveways. For heavier vehicles, a thickness of five inches is recommended. To eliminate standing water, the driveway should be sloped towards the street a minimum of one percent, or 1/8 inch per foot, for proper drainage.

If the slab is too thin, it may break under load and fail before its time. If the slab is too thick, it costs more than it should. Slab thickness is a major factor in the cost of a concrete floor, so there's often pressure, which can become intense, to make the slab as thin as possible.

3500 PSIBase Material Many basketball courts are built over a 4” thick concrete slab using 3500 PSI concrete and 1/2″ rebar reinforcements. Concrete is considered ideal for basketball courts as a permanent structure that when done right will not require any maintenance.
