This homeowner was concerned with the concrete slab which supported the fuel tanks beside his house. Over time, the slab was sinking, and so the tanks were unlevel and unstable. This before and after highlights how PolyLevel successfully leveled and stabilized the concrete slab. The only other alternative would have been to remove the tanks, pour a new slab, and replace th tanks again. The PolyLevel solution saved this customer lots of time and money.
