Polyjacking in Johnson
County, KS

Our geotechnical polyurethane foam is completely hydrophobic, meaning it does not absorb water, mix with water, or break down when exposed to moisture. During injection, if the foam encounters pockets of standing water beneath your concrete slab, it actively repels and displaces the water as it expands.

Instead of diluting (like traditional mudjacking slurry would), it maintains its chemical integrity, expands rapidly, and creates a sealed, waterproof barrier directly beneath the concrete. This prevents future water pooling and eliminates the cyclical erosion that ruins subgrade soils.

Yes. The two-part polyurethane we use is engineered as a high-density, closed-cell polymer. Once the chemical reaction completes and the foam cures (within 15 minutes), it forms a rigid, structurally stable matrix that does not shrink, crack, or become brittle when temperatures drop below freezing.

Because it fills 100% of the underground voids, it prevents meltwater from pooling directly under the slab. Without trapped water under the concrete, the destructive “frost heave” mechanism—where freezing water expands and forces concrete upward—is completely mitigated.

Absolutely. While the raw liquid components (Isocyanate and Polyol) are handled with strict industrial safety protocols inside our service trucks, their chemical reaction results in an inert, completely non-toxic solid plastic polymer.

Once cured, it is highly stable and will not leach chemicals, heavy metals, or environmental pollutants into your lawn, landscaping beds, or the local water table. It is entirely safe for residential neighborhoods, commercial properties, and municipal public spaces.

Polyjacking fixes the root cause of concrete settlement: poor soil support and empty voids. While the concrete itself may continue to age, the polyurethane foam supporting it will not degrade, rot, settle, or wash away. It stays under your slab permanently.

The only reason a polyjacked slab might settle again in the future is if the deeper, uncompacted earth layers far beneath the foam zone experience major tectonic shifting or severe subterranean erosion. For 95% of residential properties, it is a one-and- done permanent correction.

The price difference reflects raw material costs and specialized equipment. Mudjacking uses a cheap, heavy mixture of local dirt, sand, and water. Polyjacking uses advanced, engineered chemical polymers that are manufactured to strict structural specifications.

Additionally, polyjacking requires highly sophisticated, climate-controlled box trucks equipped with custom proportioners, heated hoses, and precision injection guns. You are paying for a premium material that lasts a lifetime, requires vastly smaller drill holes, saves your subgrade from heavy load stress, and eliminates the risk of future washouts.

On average, polyjacking saves property owners between 50% and 70% of the total cost of tearing out and replacing an old slab. For example, replacing a sunken three-car concrete driveway can easily cost anywhere from $6,000 to $12,000+ when you factor in demolition labor, hauling fees, landfill dumping costs, framing, rebar installation, and the price of new concrete.

Polyjacking can typically restore that exact same driveway to its original level for a fraction of that cost, while bypassing the 7-day curing delay required before you can drive on new concrete.

Polyjacking is an exceptional solution for lifting and stabilizing concrete, but it cannot perform miracles on structurally shattered slabs.

[Is your concrete a candidate for Polyjacking?]
├── YES: Slab is mostly intact, dropped in 1-2 clean pieces, or sloped toward the house.
└── NO: Slab is broken into a spiderweb of dozens of small fragments (“alligator cracking”).

If your concrete looks like a jigsaw puzzle with dozens of small, shifting pieces, the foam cannot lift them evenly because there is no remaining structural integrity across the slab. In those severe cases, full concrete demolition and replacement is your only viable path forward.

No. Polyjacking is specifically designed for slab-on-grade concrete (driveways, patios, sidewalks, garage floors, and basement slabs). Heavy load-bearing structures like a home’s main perimeter foundation wall, deep basement footings, or a solid brick chimney require massive lifting forces and deep structural anchors.

Those projects must be resolved using structural steel underpinning piers (like helical or push piers) driven deep into the bedrock, rather than chemical foam injected just below the surface.

Yes. Sinking basement floors are very common when the interior backfill soil settles over time. Polyjacking is the ideal solution for interior basement slabs because our equipment uses thin hoses that can easily run through a standard basement window or doorway.

Because our process requires zero heavy machinery inside your home and creates absolutely no dust, mud, or slurry mess, we can lift and stabilize your interior living space, utility room, or finished basement floor safely and cleanly.

Preparation is minimal and straightforward:
Clear the Area: Remove all vehicles, patio furniture, potted plants, or stored items from the concrete slabs scheduled for repair.
Clear a Path: Ensure our crew has a clear path to walk from the street or driveway to the worksite.
Pet Safety: Keep dogs and cats safely indoors during the process, as our truck engines and compressors generate moderate operational noise.
Water Access: While our trucks are fully self-contained, having an accessible outdoor water spigot is helpful for our final cleanup wash-down.

Polyjacking lifts the entire concrete slab back to its proper height and alignment, which often naturally closes up many minor cracks. However, the physical cracks themselves will still be visible on the surface.

Once our lifting process is complete, we highly recommend sealing all surface cracks and control joints with a premium, flexible, UV-resistant polyurethane concrete sealant. This

The noise level is comparable to having a standard lawn care or roof repair crew at your home. Our specialized service trucks contain an integrated motor and air compressor that runs while our technicians are actively drilling and injecting foam.

The sound is entirely localized outdoors. Because the process is incredibly fast—with most residential driveways or patios completely finished in just 2 to 4 hours—disruption to your family, your neighbors, or your commercial customers is kept to an absolute minimum.
