In addition to the soil type and expected load, the type of rebar used in the concrete slab will also affect the thickness. Rebar is a type of metal reinforcement that is embedded in the concrete to add strength and durability.

The type of rebar used will vary depending on the size and shape of the slab, and the type of soil the slab is placed on. Generally, the thicker the rebar, the thicker the slab should be. The
