The concrete sidewalk leading to this entrance had begun to settle, creating a noticeable tripping hazard for anyone entering the building. To restore the sidewalk to its proper height, our team used PolyLevel®, an advanced polyurethane foam injection system. The foam first fills the voids beneath the concrete before gently lifting and leveling the slab back into place. Best of all, the sidewalk was ready for normal use in as little as 15 minutes, minimizing disruption while providing a long-lasting solution.
