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.
Generally, granite countertops are between half an inch and an inch and a half thick. The thickness of a granite countertop is directly proportional to its dimensions. Therefore, a countertop that measures 96 square inches, which can cover an entire kitchen surface, will probably be between an inch and a quarter and an inch and a half thick.
