Polyjacking & Concrete Leveling in Leavenworth, KS
Sunken driveways, uneven sidewalks, and settled patios across Leavenworth. We lift concrete back to level in hours — no tear-out, no mess.
How Does Concrete Leveling Work in Leavenworth?
Driveways, sidewalks, patios, and garage floors across Leavenworth settle over time as the soil beneath them washes out or compacts. The heavy clay soil in Leavenworth 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.
Old brick and stone foundations here are frequently compromised by the freeze-thaw cycles common in the river valley.
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 Leavenworth homeowners tired of stepping over that uneven sidewalk or cringing at the sunken driveway, polyjacking is the fast, affordable fix.
What Concrete Problems Affect Leavenworth Homes?
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.

Polyjacking & Concrete Leveling in Leavenworth — FAQ
Polyjacking costs in Leavenworth depend on the area being lifted and the number of injection points needed. Most residential projects in Leavenworth County range from $1,000 to $5,000 — roughly half the cost of tearing out and replacing the concrete. We provide a free assessment with exact pricing before any work begins.
The heavy clay soil in Leavenworth County shrinks during dry periods, creating voids beneath concrete slabs. Gravity pulls the slab down into these voids, and the damage worsens with every wet-dry cycle. Leavenworth's driveways, patios, sidewalks, and garage floors are all susceptible — especially where the soil was backfilled during construction and never properly compacted.
Yes. Polyurethane foam is lighter than mudjacking slurry, so it won't add excessive load to Leavenworth County's already-weak soil. It's also waterproof — mudjacking slurry can wash out and erode over time in our wet climate. The foam cures in about 15 minutes (vs. 24-48 hours for mudjacking), and the injection holes are penny-sized instead of golf-ball-sized.
In most cases, yes. Garage floors are one of our most common polyjacking projects in Leavenworth. If the concrete itself isn't severely broken or crumbled, we can lift and level it by injecting polyurethane foam through small holes. You can park on it the same day. We'll tell you honestly during the free assessment whether polyjacking is the right fix or if replacement makes more sense.
Polyurethane foam is permanent — it doesn't wash out, erode, or break down over time. The foam is waterproof and unaffected by Leavenworth County's moisture cycles. Once the void is filled and the slab is lifted, the repair holds. That said, if the underlying soil conditions aren't addressed (like poor drainage causing ongoing erosion), new voids can form adjacent to the repair. We evaluate the full picture during your free assessment.
We polyjack driveways, sidewalks, patios, pool decks, garage floors, and front stoops throughout Leavenworth. As long as the concrete slab is intact (not broken into multiple pieces), polyjacking can lift it back to level. The process takes a few hours for most projects, and you can use the surface the same day.
