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.
The cost to install a 100-square-foot concrete countertop averages between $8,500 to $10,000. Concrete countertops have evolved since the 1980s. They used to be poured into a mold; now they are precast and delivered as finished products.
