Why does concrete settle in Lee's Summit?

Concrete settlement is common throughout Lee's Summit due to shifting clay soils, changing moisture levels, heavy rainfall, and Missouri's freeze-thaw cycles. Over time, these conditions can wash away or compress the soil beneath your concrete, causing driveways, sidewalks, patios, and garage floors to sink. PolyMagic uses expanding polyurethane foam to stabilize the soil and lift the slab back into place without replacement.

Patios and porches are exposed to the same freeze-thaw stress as driveways but often see water pooling as an added problem when the slab settles toward the house. A porch slab that has dropped is directing water where you don't want it. Lifting it back corrects the slope and protects the structure behind it.

Lee's Summit grew fast. Through the 1980s, 1990s, and into the 2000s, subdivisions spread across Jackson County's eastern edge and thousands of driveways, sidewalks, patios, and porches were poured to keep pace. The concrete went in quickly, and in many cases the base preparation underneath it was minimal. That concrete is now 25 to 45 years old, sitting on one of the heaviest concentrations of Wymore-Ladoga clay in the Kansas City metro through more than 100 freeze-thaw cycles every year. The result is that homeowners all across Lee's Summit are dealing with the same problem at roughly the same time. It is not a coincidence. It is an entire city's worth of concrete reaching its first major repair window simultaneously.

Replacing the concrete does not solve the problem. New concrete over the same unsupported clay will follow the same path. Polyjacking addresses the cause directly with small holes are drilled through the settled slab, expanding polyurethane foam is injected beneath it, and the foam fills the voids, re-establishes a stable base, and raises the concrete back to its original elevation. The holes are patched, vehicle traffic resumes in about 30 minutes, and the foam holds through the same wet-dry cycles that caused the original failure. The work is backed by a 5-year warranty, and PolyMagic's foundation repair background means every job starts with understanding why the slab settled, not just lifting it back into place.

Driveways

Driveways are a common issue in Kansas City area neighborhoods. Settling at the garage transition, drops along joints, or slopes towards the home create drainage and cosmetic problems. Concrete driveway leveling realigns slabs without the cost or disruption of full replacement.

Sidewalks

Uneven sidewalks and walkways create trip hazards. Whether it's the path to your front entry or the sidewalk beside your house, proper repair eliminates height differences. In the Kansas City area's older neighborhoods, shifted panels can often be lifted instead of replaced.

Patios

Patios and porches are exposed to the same freeze-thaw stress as driveways but often see water pooling as an added problem, especially when the slab settles toward the house. A porch slab that has dropped is directing water where you don't want it. Lifting it back corrects the slope and protects the structure behind it.

Garage Floors

Garage floors can settle at the apron where the slab meets the driveway or develop low spots from subbase shifting. Concrete slab repair for garages in the Kansas City area is a clean polyjacking process that is well-contained, leaves a neat finish, and allows the space to be used almost immediately.
