Quick Answer
Lift the slab you already have.
Polyjacking—also called polyurethane concrete lifting, polyfoam lifting, foam jacking, or poly lifting—places expanding structural foam beneath settled concrete. The foam fills hidden voids and raises the slab in controlled stages.
When the concrete itself is still structurally usable, polyjacking can be a faster, cleaner, and less disruptive alternative to tearing it out and pouring a new slab.
How Polyjacking Works
Small ports. Expanding foam. A controlled lift.
- 01
Inspect
We evaluate slab condition, settlement, voids, access, drainage, cracks, and nearby fixed surfaces.
- 02
Plan
Injection locations are selected so the concrete can be lifted gradually and monitored throughout the repair.
- 03
Inject
Two-part polyurethane enters as a liquid, expands beneath the slab, and fills unsupported space.
- 04
Lift and finish
The slab is raised toward the planned elevation, the ports are patched, and the work area is cleaned.
Concrete We Level
Polyjacking for Kansas City homes and properties.
Every slab must be evaluated, but polyurethane foam can be used for many residential and commercial concrete applications.
Sidewalks
Correct uneven joints and reduce trip hazards on residential and commercial walkways.
Patios
Restore support beneath outdoor slabs and improve areas that hold water or slope the wrong way.
Garage floors
Lift eligible settled sections and improve rough transitions near the garage door.
Porches and steps
Evaluate sunken landings, step units, and entry transitions around fixed surfaces.
Pool decks
Improve uneven walking surfaces around eligible concrete pool-deck panels.
Why Concrete Settles
Kansas City soil and water can leave a slab unsupported.
Changing moisture, expansive clay, erosion, drainage problems, and poorly compacted fill can create empty space beneath concrete. Once a slab loses even support, it may sink, tilt, collect water, or create an uneven transition.
Polyjacking addresses that lost support, but the repair plan also needs to consider why the void formed. We evaluate downspouts, grading, soil gaps, cracks, joints, doors, curbs, foundations, coping, and neighboring panels before planning a lift.
Polyjacking vs. Mudjacking
Two lifting methods with important differences.
Polyjacking
- Expanding structural polyurethane foam
- Small injection ports
- Lightweight material
- Fast curing
- Controlled expansion into voids
Traditional mudjacking
- Cement, soil or sand, and water slurry
- Larger drilled holes
- Heavier material beneath the slab
- Longer setting time
- Pumped slurry placed from each hole
Polyjacking Cost
Pricing depends on what is happening beneath the slab.
The cost of polyjacking in Kansas City depends on slab size, the amount of settlement, hidden void volume, required polyurethane, job access, nearby fixed surfaces, and the result that can safely be achieved. That is why a square-foot price alone rarely tells the full story.

Good concrete is often worth saving.
Polyjacking is most useful when the concrete remains structurally usable and settlement is the main problem. Replacement may be the better investment when a slab is badly broken, crumbling, severely deteriorated, or unable to move safely around fixed structures.
Existing cracks, discoloration, and surface wear remain after lifting. The goal is to restore support and improve elevation—not disguise concrete that has already failed.

What Kansas City property owners ask us.
What is polyjacking?
Polyjacking injects expanding structural polyurethane foam through small ports in a settled slab. The foam fills unsupported space and raises the concrete in controlled stages.
Is polyjacking the same as concrete leveling?
Polyjacking is one concrete-leveling method. You may also hear it called polyurethane concrete lifting, polyfoam lifting, foam jacking, or poly lifting.
Is polyjacking better than mudjacking?
Polyjacking uses lightweight foam and smaller ports, while mudjacking uses a heavier cement-based slurry through larger holes. Slab condition, soil, drainage, access, and fixed surfaces still determine the right repair.
Will polyjacking remove existing cracks?
No. Lifting can restore support and improve elevation differences, but existing cracks, color differences, spalling, and surface wear remain visible.
Can every sunken slab be lifted?
No. Badly deteriorated or shattered concrete may need replacement, and attached structures or fixed elevations can limit how much a slab can safely move.
How much does polyjacking cost in Kansas City?
Pricing depends on the actual slab, settlement, void volume, foam quantity, access, and lifting plan. Send photos and measurements for a free project review.
