The City of Stamping Ground, KY, identified multiple public safety hazards across several addresses, including sections of Main Street, residential sidewalks, and areas around municipal buildings. Over time, concrete slabs had shifted and separated, creating uneven surfaces that posed a tripping hazard for pedestrians. In some locations, manhole covers and sanitary access points had settled below grade, leaving sharp elevation changes in the walking surface. Because these hazards were scattered across the city — from sidewalks near the post office to intersections along Main Street — the project required a solution that could be applied quickly with minimal disruption to daily foot traffic.
Solution
Our team used PolyLevel® expanding foam to lift and level uneven concrete slabs and restore settled areas around manhole covers. PolyLevel is injected through small holes in the slab, expanding underneath to gently raise the concrete back into place. One of its biggest advantages for municipal projects is speed — it cures in just 10 minutes, meaning sidewalks and streets could reopen almost immediately after repair. We followed the lifting process with NexusPro® joint and crack sealant to protect the concrete from future water infiltration and freeze-thaw damage. By coordinating work across multiple addresses in a single mobilization, we helped the City of Stamping Ground eliminate trip hazards, extend the lifespan of their concrete infrastructure, and keep residents safe — all with minimal downtime.
