Around the edge of the slab, the concrete forms a beam that is perhaps 2 feet deep. The rest of the slab is 4 or 6 inches thick. A 4- or 6-inch layer of gravel lies beneath the slab. A 4-millimeter sheet of plastic lies between the concrete and the gravel to keep moisture out.
Do you need rebar for 4 inch slab?
If you don't put rebars in a 4-inch [10 CM] slab, then it won't be reinforced concrete - and won't perform. As a general rule, any section of concrete must have at least 0.25% of its area in rebars to be considered reinforced concrete and do the intended job.
