Weight A 1 Â½ inch thick countertop made of standard concrete has an approximate weight of 18.75 pounds per square foot. (Granite is approximately 18 pounds per square foot.) Standard cabinetry will typically support this weight because itâs distributed over a large area.
This countertop illustrates how concrete can be used to create a 3-dimensional look. The interior of this countertop is 2-inches thick, but the exterior (the drop nose feature) is 9-inches thick. It gives the illusion that the countertop is one massive piece of concrete.
