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.
If the finished countertop is going to be granite, the level-line will be 19 1/2 above the base cabinets as the thickness of the granite and the 5/8 thick plywood subtop it's set on will be about 1 1/2 thick total.
