How thick should my concrete slab be?

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.

The Thickness Of Concrete Planters For Durability The thickness of a planter needs to be a minimum of ⅜” thick.

How early should the curing begin? Curing should begin as soon as compaction and finishing is completed and before concrete surface looses its water and undergo shrinkage. This is very important for concrete with low to very low water/cement ratio, which does not have much water to bleed to the surface.

Five to six inchesFive to six inches is recommended if the concrete will receive occasional heavy loads, such as motor homes or garbage trucks.

four inchesAs 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.

Joints should be sawed as soon as the concrete will withstand the energy of sawing without raveling or dislodging aggregate particles. For most concrete mixtures, this means sawing should be completed within the first six to 18 hours and never delayed more than 24 hours.

The minimum depth of sawcut using an early-entry dry-cut saw should be 1 in. ... Some slab designers require cutting the slab the following day to 1/4 of the slab depth to deepen the 1 in.

6 inches thickTo be structurally sound, a concrete pool shell should generally be 6 inches thick. Depending on the engineer and the soil condition, it may be more. (On top of that, the plaster interior finish should be at least ⅜ inch thick.) The pool will also need to meet the ANSI/APSP standards.

4 inchesFor a concrete driveway to last the life of your home, it must be well constructed.

The base should extend at least 300mm beyond the widest points of the oil tank and fully support the base of the oil tank in its entirety..

Sealing products can not be used on newly poured concrete. Homeowners would have to wait 28 to 30 days when the concrete has completely cured. Applying the sealer too early will be detrimental to the durability of the new concrete slab.

between 85mm and 100mm“Slab” issues that most often arise in disputes between builders and owners relate to the size of cracks that may appear, and the thickness of the concrete slab installed. In Western Australia the most common slab thickness is between 85mm and 100mm.

Therefore I recommend that all the walls should be at least 9 inch thick. 4.5-inch thick walls are not structurally safe if they are beyond 7 feet in height or carry some imposed load.
