This homeowner in Clark, New Jersey noticed their concrete patio was unlevel and becoming a safety hazard. If this goes without repair, someone could trip and severely injure themselves. They contacted Quality 1st Basement Systems where our System Design Specialist, Alvin Reed, provided an inspection. Alvin suggested they use polyurethane foam to bring the concrete to a level position. Our foreman, Ramon Romero, used PolyLevel Injections to be injected underneath the slab and into the voids. Within 20 minutes, the concrete was brought to a lifted position, and it was safe to walk on again!
