Dear Big Al, I am considering concrete countertops for my kitchen renovation. I am using my old cabinets and I was wondering if they will support a concrete countertop. How heavy are they? Dianna, Shelbure Falls MA
Good one Dianna,
One and one half inch thick Concrete countertops weigh around eighteen pounds per square foot. Alpha Stone Concrete uses a light weight aggregate to keep the weight down and make our concrete products more environmentally friendly. Our concrete weighs about thirteen pounds per sq/ft. So a countertop that is twenty-five inches wide and eight feet long would weigh around two hundred and twenty pounds. Sink openings will reduce the weight by somewhere around forty to sixty pounds. That may seem heavy to you but we have seen old or inexpensive base cabinets support the weight with no problem. Base cabinets are basically a box, a structure that is very strong. Also, the weight is evenly distributed over the base cabinets. Any good template guy will inspect your cabinets to determine if there will need to be any reinforcing or modifications to your base cabinets.
Thanks for the weighty question,
Big Al
