I have a concrete pad around a 20x40 pool that has multiple cracks in it. There are numerous expansion joints around the entire pad and in one section by the pool entry steps it has sunk about 11/2 to 2 inches. It's probably about 25 years old and looks really bad, there's no flaking anywhere, just ugly cracks every where. I was thinking about looking into a pebble stone epoxy overlay to dress it up, but I don't know much about this process and whether it's worth it or not. Does anybody have any ideas good or bad on this?
