Has anybody ever had a one to two ton safe installed on anything but a concrete slab? Just at the daydreaming stage at this point but wondering if any wood floor is capable of it. Looking at the Brown 7256, and at the lightest a TL-15 is 4880 pounds. Where I would like to put it is a small twenty year old addition on an older house. I am taking for granted that the floor has to come up for reinforcement of both joists and the floor itself. Worse case would be fill in with pea gravel and pour concrete.
