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.

However, most clients want to minimize the number of seams, so this is usually not practical. â Make thinner (precast) slabs.
