Concrete Leveling & Slab Leveling Services in Leawood, KS
Sunken driveways, uneven sidewalks, and settled patios across Leawood. We lift concrete back to level in hours — no tear-out, no mess.
Why Does Concrete Settle and Sink in Leawood?
Driveways, sidewalks, patios, and garage floors across Leawood settle over time as the soil beneath them washes out or compacts. The heavy clay soil in Johnson County shrinks during dry spells, creating voids under concrete slabs. Once the support is gone, gravity pulls the slab down — and it only gets worse.
JLB has a physical location here. High-value finished basements in Southern Leawood make even minor water leaks a major financial concern.
Polyjacking lifts settled concrete back to level by injecting expanding polyurethane foam through penny-sized holes. It fills the void, compacts loose soil, and raises the slab — all in a few hours. No jackhammers, no week-long cure time, and you can walk or drive on it the same day. For Leawood homeowners tired of stepping over that uneven sidewalk or cringing at the sunken driveway, polyjacking is the fast, affordable fix.

What Signs of Concrete Settlement Should Leawood Homeowners Watch For?
These are the signs your concrete has settled and could use leveling.
Driveway Sunken Near the Garage
That lip where the driveway meets the garage? You feel it every time you pull in. It catches wheels, scrapes bumpers, and looks worse every season.
Sidewalk Sections Tilted or Uneven
Guests trip on it. You step over it out of habit. It looks bad and you know it — and so does everyone who walks up to your front door.
Patio Sloping the Wrong Way
Your patio furniture wobbles. Drinks slide. Rain puddles where you sit instead of draining away. It's annoying every single time you use it.
Pool Deck or Porch Sinking
A settling porch or pool deck looks neglected. The gaps between slabs catch toes and collect dirt. It makes the whole backyard look rough.
Water Puddles That Won't Drain
Standing water on your driveway or patio after every rain. It sits there for days, grows algae, and makes your concrete look stained and sloppy.
Visible Gaps Under Slab Edges
You can see daylight under the edges. The concrete is floating over a void, it looks uneven, and it's only going to settle more.

Four Steps to Level Concrete
Most polyjacking jobs are done in a few hours. Here's the process from start to "walk on it today."
Free Assessment
We measure the settlement, identify void locations, and give you an exact quote. No pressure, no upsells — just an honest assessment of what needs leveling.
Small Holes, Big Results
We drill penny-sized holes through the slab at strategic points. These are the injection ports — and they're nearly invisible when we're done.
Foam Injection & Lift
High-density polyurethane foam is injected through the ports. It expands beneath the slab, fills the void, and lifts the concrete back to level with millimeter precision.
Patch, Cure, Walk
Holes are patched, foam cures in 15 minutes, and you can walk and drive on the slab the same day. Done.

What Does Polyjacking & Concrete Leveling Cost in Leawood, KS?
Sunken concrete in Leawood is almost always caused by Johnson County's clay soil shrinking during dry spells and creating voids beneath the slab. Polyjacking fills those voids and lifts the concrete back to grade — for 50-70% less than replacement. Here's the pricing breakdown.
| Project Type | Typical Cost Range | Notes |
|---|---|---|
| Sidewalk section (1–2 slabs) | $300–$800 | Most affordable concrete leveling project |
| Driveway leveling | $800–$2,500 | Depends on number of injection points |
| Patio leveling | $500–$1,500 | Depends on size and number of voids |
| Garage floor leveling | $600–$2,000 | Often combined with driveway work |
| Pool deck leveling | $1,000–$3,000 | Requires precision for drainage slope |
| Per-hole injection point | $150–$350 | Most projects need 4–12 injection points |
These ranges reflect typical Kansas City metro pricing as of 2026. Actual costs vary based on the area being lifted, number of injection points, and accessibility. JLB provides free assessments — call (816) 408-3651 for an accurate quote.
Concrete Leveling Questions for Leawood Homeowners
Leawood's affluent neighborhoods feature longer driveway spans and wider concrete sections that distribute weight differently across Johnson County's clay soil. Properties in Hallbrook and along the 135th corridor often have driveways spanning 40-60 feet with multiple vehicle accommodations, requiring more strategic injection points to achieve uniform lifting. The deeper basements typical of 1980s-2010s construction also mean your driveway spans greater distances over potentially unstable soil, making precise foam placement critical for preventing future settlement across these extended concrete surfaces.
Your sloped terrain creates unique drainage patterns that affect how polyurethane foam injection must be approached in Leawood's rolling neighborhoods. The extensive landscape grading around State Line and Mission Hills adjacent areas means water flows differently beneath settled concrete, requiring injection strategies that account for gravity-driven moisture movement through Johnson County clay. Sidewalks and patios on sloped lots also experience different settling patterns than flat properties, often tilting toward or away from your home rather than settling uniformly, demanding more sophisticated lifting techniques to restore proper drainage angles.
Leawood's 9-foot and deeper basements create more significant structural loads above garage floors, requiring different polyurethane foam injection pressures than standard Johnson County applications. Walk-out basement configurations common in neighborhoods like Hallbrook mean your garage floor must support greater weight while spanning longer distances over Johnson County clay. The high-end finished basements typical of 1980s-2010s Leawood construction also mean garage floor settling affects more valuable living space below, making precision lifting essential to prevent cracks in finished basement walls and floors.
Your area's substantial rainfall creates more dramatic clay soil movement cycles than drier Johnson County locations, requiring careful timing of polyjacking projects around seasonal moisture patterns. The rolling terrain and sloped lots throughout Leawood mean water concentrates differently around concrete surfaces, particularly affecting driveways and walkways near the 135th corridor where grading channels runoff. Polyurethane foam injection works best when Johnson County clay reaches optimal moisture content, typically after spring runoff but before summer heat causes soil shrinkage that could affect newly leveled concrete surfaces.
The premium landscaping and complex grading typical of Leawood properties create unique access challenges for concrete lifting equipment around State Line and Mission Hills adjacent neighborhoods. Your sidewalks often wind through mature landscaping and decorative features that require more precise, minimally invasive polyjacking techniques to avoid damage. The longer spans between expansion joints common in affluent construction also mean patio sections settle in larger blocks, requiring more strategic foam injection patterns to achieve uniform lifting across these extended concrete surfaces while preserving the aesthetic integration with your property's high-end hardscaping.
