A homeowner in Gladstone, near the Antioch Shopping Center area, called about their front porch slab that had sunk nearly two inches. The slope was now angling toward the house instead of away from it, creating a trip hazard at the front steps and directing rainwater toward the front door.
Clay County's soil is notorious for settlement — the clay expands and contracts with moisture cycles, slowly pulling support from beneath concrete flatwork. A short section of the front sidewalk had started sinking too, creating an uneven walking surface for visitors.
Our polyjacking crew drilled small injection ports through the concrete and pumped high-density polyurethane foam underneath to lift and level the slab back to its original position. The foam expands to fill voids and cures in minutes, providing permanent structural support.
The entire job — porch and sidewalk — took about three hours. No demolition, no heavy equipment, no torn-up landscaping. The small injection holes were the only evidence of the work. Polyjacking is a fraction of the cost of replacement and the homeowner had a solid, level porch again by that afternoon.
