"It [GatorBar] is so easy to work with it feels like we are cheating! We have always used a #4 steel rebar grid in warehouse slabs to add structural integrity, but no matter how hard you try, 6x6x10/10 wire mesh always ends up on the bottom of the slab. There is never enough time to pull it up, and even if you Dobie it up, the steel bends down when you step on it. In the end, it does not add structural strength to the slab. GatorBar springs back, staying centered in the slab."
