The mining industry spans the globe, as do alumni of the University of Arizona mining and geological engineering program. Many got their feet wet working as interns for Arizona-based mining companies like Freeport-McMoRan.
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 countertop rests on a base of Â½-inch-thick cement board, enabling you to keep the concrete 1 inch thick except at the edges, which are just deep enough to hide the cement board. The result is a normal-height countertop that's easily supported by standard cabinets.
