Concrete Walkway Trip Hazard
The homeowner observed differential settlement along the front walkway, resulting in uneven slab elevations. This was attributed to subsurface voids in the soil, likely caused by erosion or inadequate compaction. The resulting height discrepancies created a significant trip hazard directly outside the main entrance, raising safety concerns.
Slab Jacks
Slab jacking techniques were employed to realign the displaced concrete slabs to their original grade.
PolyLevel
PolyLevel®, a high-density polyurethane foam, was injected beneath the concrete slab through strategically drilled, pea-sized ports. Upon injection, the foam rapidly expands to fill underlying voids and compact loose soil, providing immediate stabilization. This method effectively restores structural integrity and ensures long-term support for the walkway.
Trip Hazard Eliminated
The walkway has been successfully restored to a level and uniform condition, as visually confirmed in the accompanying photo. This remediation has alleviated safety concerns, providing the homeowners with confidence that the entryway is now secure and accessible for all visitors.
