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.
But if you are interested in a kitchen countertop, the answer is (according to the Home Depot rep) either 20 or 40 mm. But according to Dekton, they make countertop sheets only as thick as 20 mm. So my guess is that to produce a 40 mm thickness, the Home Depot fabricator (not Dekton) must bond two 20 mm sheets together. Suggest you carefully verify this with Home Depot if this is important to you.
