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.
For designs where your countertop is cantilevered or overhangs the supports, overhanging portion should be limited to 6 for Â¾ (2 CM) thick countertops and 10â for 1Â¼ (3 CM) stone countertops. The overhang should never be more than 1/3 of the depth of the countertop (front to back as your facing it).
