In Arlington Heights, a homeowner was troubled by sinking stairs at the entrance, posing a serious safety concern and tripping hazard. This noticeable problem, depicted in the ‘before’ section, required a prompt and efficient solution. By implementing our PolyLevel® system, we skillfully addressed this issue as seen in the ‘after’ photo. The process involved injecting high-strength polyurethane foam to lift and stabilize the concrete, restoring the integrity and safety of the stairs. This effective concrete repair not only enhanced the appearance but also ensured long-lasting durability and peace of mind.
