Drilling a small injection port into a concrete slab with a rotary hammer drill -- PolyJacks concrete leveling serving Kansas City, KS.
Where we work

Concrete Leveling Near Me — Across the Kansas City Metro

Based in Spring Hill, KS, we cover Johnson, Wyandotte, Jackson, Clay & Platte counties — both sides of the state line.

Based in Spring Hill. Working All Over the Metro.

Andrew started PolyJacks in 2024 after years in the trades, watching driveways, sidewalks, and patios sink all over Kansas City. Sunken concrete isn't just a Spring Hill problem or an Overland Park problem. It's a whole-metro problem, because the clay under all of us behaves the same way.

We run out of Spring Hill, Kansas, and cover roughly a 50-mile radius from there. Every county on both sides of the state line: Johnson and Wyandotte in Kansas, Jackson, Clay, and Platte in Missouri. That's close to 35 towns and suburbs, residential and commercial, and we go out to about 100 miles for larger commercial work.

Wherever you're at in that circle, you get the same crew, the same waterproof foam, the same free estimate, and the same 1-year transferable warranty. No second-tier service because you're 40 minutes from our shop instead of 10.

Why Concrete Sinks the Same Way in Every One of These Towns

It's not bad luck and it's not bad concrete. It's what's underneath it. KC metro soil is heavy clay, and clay swells when it's wet and shrinks when it dries out. Every single season, year after year. On top of that, we get somewhere between 50 and 100 freeze-thaw cycles most winters. Water gets under a slab, freezes, expands, thaws, and repeats. That cycle hollows out voids under concrete no matter which county you're in.

A few things speed it up: erosion from bad drainage or downspouts dumping water right next to the slab, fill dirt that wasn't compacted right when a driveway or patio was poured, tree roots pulling moisture out from under a slab, and plumbing leaks washing soil away underneath. Fix the cause, and lifting the slab back level is usually permanent.

Same soil, same weather, same fix: whether you're in Olathe or Independence.

Not Sure You're in Range? Call Anyway

Our stated radius is about 50 miles from Spring Hill for houses and about 100 miles for commercial properties, but that's a guideline, not a hard line on a map. If your town is close to the edge, or you just don't see it listed yet, call (913) 713-7794 and ask.

A free on-site inspection is how every estimate starts anyway. That's when we actually see your slab, measure the void, and tell you what it'll take. There's no cost and no obligation to find out.

The Same PolyJacks Job, No Matter the Zip Code

Three-step process timeline: free on-site inspection, a written quote, then the lift finished in hours
The three-step process: inspect, quote, lift.

Every job in every one of these towns follows the same process. We drill dime-sized holes (usually 4 to 12 of them) and inject a waterproof, high-density polyurethane foam that expands 30 to 40 times its liquid volume to fill voids and lift the slab. Most jobs take 2 to 4 hours. You can walk on it in 15 to 30 minutes and drive on it in 1 to 2 hours; we just ask you keep heavy vehicles off it for 48 hours.

It runs far less than tearing out and replacing the concrete, and because the foam is waterproof and won't shrink or break down, the lift holds. Every job is backed by a 1-year limited warranty, transferable if you sell the property, and we'll re-lift for free if the slab settles more than 1/4 inch within 12 months due to our work.

We're licensed and insured, and every estimate is free. Book a Free Estimate or call (913) 713-7794.
