Do you need rebar for 4 inch slab?
The thickness of rebar should be no more than 1/8 that of the slab, so a 4” slab shouldn’t have steel greater than #4 or 1/2″ bar. It’s best to check with a Structural Engineer if your slab will bridge or cantilever. What is this? For 4” concrete slabs used for driveways and patios, #3 rebar is common.
How deep should I dig for a concrete slab?
Excavate the slab area to a depth of about 7 inches, allowing 3 inches for a gravel base and 4 inches for concrete.
How thick should a concrete slab be?
Standard concrete floor slab thickness in residential construction is 4 inches.

To prepare the base, cut the ground level to the proper depth to allow for the slab thickness.
How much weight can a 12 inch concrete slab hold?

How strong is 3 inches of concrete?
So, the “4,000 PSI” rating is for the standard 4-inch thickness of a residential concrete slab. This means that a 3-inch slab will be slightly weaker, while a 5-inch slab will be slightly stronger, in terms of compressive strength. Tensile strength is a bit harder to measure.
How much load can a slab of concrete hold?
Imposed loads varies from approximately 1.5 kN/m2 (153 kg/m2) in domestic buildings to approximately 10 kN/m2 (1053 kg/m2) in heavy industrial areas. 500 kg/m2 is typical for office, storage space and similar.
