Hmmmm, so the weld is only for keeping the seam area sealed and not hold adhere the edges together? Gee, never heard that before, who told you that?

This slab is in a 20 year old strip mall. Please re read the previous posts. It has an older floor in the back, same stuff (15 years old) that is not exhibiting any moisture issues or shrinking.
