What Are The Thickness And Weight Of Concrete Countertops?
The standard slab thickness is 1.5″. Two inch slabs are also quite common. Larger thickness is also possible and is done for aesthetic reasons. If a 6″ slab is desired, however, the back and center are still 1.5″ thick and the front grows to the desired thickness. So it still looks 6″ thick but is only 6″ thick in the front. A 1.5″ thick standard concrete countertop has an approximate weight of 18.75 pounds per square foot. (Granite is approx. 18 pounds per square foot). The countertop weight can be less if lightweight concrete is used. Standard cabinetry will support the concrete slabs as the weight of the countertops is distributed over a large area.
