This homeowner in Pennsville, New Jersey noticed their pool patio was beginning to sink and become unlevel. This happens because the soil underneath the concrete is poorly compacted. Over time, this soil settles and creates voids underneath the concrete. The homeowner contacted Quality 1st Basement Systems and our System Design Specialist, Chris Bowe, provided an inspection and suggested they use polyurethane foam. Our foreman, Ramon Romero, began installing our PolyLevel Injection System. This is done by drilling tiny holes into the concrete and injecting the foam into the voids underneath. PolyLevel has expanding properties that allow for accurate lifting and leveling of the slab. Now, the homeowner doesn't have to worry about tripping near their home!
