Polyjacking uses expanding polyurethane material introduced beneath settled concrete to fill voids, restore support, and provide a controlled lift where the slab condition supports it. Typical applications include driveway panels, sidewalks, patio slabs, pool decks, walkways, and other suitable flatwork where the concrete is largely intact but has dropped, tilted, or lost the support beneath it. The method selection depends on slab condition, the settlement pattern, access, the size of any void, the amount of lift needed, the surrounding surfaces, and project economics — polyjacking is not the right answer for every slab. Because polyurethane material is comparatively lightweight versus traditional cementitious mudjacking slurry, it adds little load to the underlying soil, and the injection openings are generally smaller than traditional mudjacking access holes. Fast curing can be an advantage that supports a quicker return to use, but universal immediate use is not promised. See our concrete leveling methods comparison or the homepage overview for the broader context.

Gilbert outdoor concrete experiences intense heat and seasonal moisture swings that can contribute to ground movement beneath exterior flatwork, though no single soil mechanism explains every case of settlement. Polyjacking cannot make severely deteriorated concrete structurally new — when a slab is badly fragmented, extensively cracked, or deteriorated, replacement may be the more appropriate path. And concrete leveling, including polyurethane foam leveling, is not foundation repair; it addresses settled exterior flatwork and the support beneath it, not a building's structural foundation. With 10+ years of experience and insured service, Gilbert Concrete Leveling evaluates whether polyjacking fits your slab before recommending it, and explains the repair-vs-replacement tradeoff honestly.

Why Choose Gilbert Concrete Leveling for Polyjacking in Gilbert?

Polyjacking is one of several leveling methods, and it fits some slabs better than others. Our role is to inspect the concrete first and recommend foam leveling only where the conditions support it.

  • 10+ Years of Experience

    A decade of selecting between polyurethane foam, mudjacking, and void filling based on what each slab, void, and access situation actually requires.

  • Insured

    Gilbert Concrete Leveling is insured for the polyjacking and concrete leveling work we perform on your property.

  • Method Selection Based on Slab Condition

    Polyjacking is recommended only after the slab condition, void size, and lift requirement are evaluated — not as a default answer for every settled slab.

  • Experience With Driveways, Sidewalks, Patios, and Pool Decks

    Hands-on polyurethane foam leveling across the common residential flatwork types found on Gilbert properties.

  • Understanding Void Filling vs Actual Lift

    We distinguish between a slab that needs to be lifted and a slab that needs support restored beneath it, because those are different objectives even within polyjacking.

  • Repair-vs-Replacement Guidance

    When a slab is too deteriorated for foam lifting, you get an honest recommendation for replacement instead of a repair that will not hold.

  • Clear Estimates and Process

    Pricing is explained by the factors that drive it — slab area, panels, lift, foam volume, and access — and the process is laid out plainly.

  • Local Drainage, Heat, and Moisture Considerations

    Familiarity with Gilbert heat exposure, monsoon moisture, drainage, and soil movement that affect how exterior slabs settle here.

Our Polyjacking and Foam Concrete Leveling Services

Each application below uses expanding polyurethane foam to fill voids and lift a specific type of settled concrete where the slab is still sound enough to lift.

Polyurethane foam injection through small holes in a concrete driveway slab

Driveway Polyjacking

Driveway polyjacking raises settled driveway panels back toward the adjacent surface, particularly where a panel has dropped at the garage apron or between adjoining sections. It applies to Gilbert driveways where the panels are intact but have lost elevation or support.

Expanding polyurethane foam is injected through small openings at lift points beneath the settled panels to fill the void and produce a controlled lift, with attention to the garage transition, the surface slope, and the control and expansion joints between panels.

The result is a smoother, more even driveway with a reduced transition lip and improved drainage away from the garage, achieved with small injection holes and a lightweight material that preserves the existing concrete.

Sidewalk Polyjacking

Sidewalk polyjacking lifts a sidewalk panel that has settled below its neighbor, removing the trip hazard that forms at the joint between the two panels. It is used on pedestrian walks where the concrete is intact but one section has dropped.

Polyurethane foam is introduced through a compact pattern of small injection holes beneath the lower panel to fill the void and raise the concrete back into alignment, restoring an even joint line with a minimal access footprint.

The outcome is a safer walking surface with the trip transition reduced at the joint, preserving the existing sidewalk panel instead of cutting and repouring the section.

Pool Deck Polyjacking

Pool deck polyjacking addresses settled sections of the concrete deck surrounding a swimming pool, where slabs often drop near the coping and create uneven transitions. Arizona pool decks are exposed to intense sun and moisture swings that can affect the support beneath them.

Small-diameter injection holes keep disruption to the deck minimal, and lightweight polyurethane foam fills voids and lifts the settled section back toward the coping and adjacent slabs. The deck condition is evaluated to confirm the sections are sound enough to lift.

The result is a more even, safer surface around the pool with improved transitions, restoring the usable deck without the mess and downtime of tearing out and repouring pool deck concrete.

Patio and Walkway Polyjacking

Patio and walkway polyjacking lifts settled exterior flatwork near doors, paths, and landscaped areas where a slab has dropped at a corner or edge. It applies to patios and walkways that are intact but have tilted, lost support, or developed a low spot.

Polyurethane foam is injected beneath the settled area to fill the void and bring the surface back toward level, with attention to how the patio or walkway drains away from the home and the transitions to adjoining surfaces.

The outcome is a flatter, more usable outdoor surface with improved drainage and a reduced trip edge, keeping the existing patio or walkway slab in place rather than replacing it.

Void Filling With Polyurethane

Void filling with polyurethane addresses the open space that forms beneath a slab when soil erodes or settles away from the underside of the concrete, even before the surface has dropped significantly. It applies where the support beneath a slab has been lost.

Expanding polyurethane foam is introduced beneath the slab to fill the void and re-establish bearing under the concrete. This is distinct from forcing an unnecessary lift — the goal may be to fill and stabilize rather than to raise the slab at all.

The result is a slab with restored support beneath it, reducing the conditions that can lead to further settlement and cracking where the underlying void has been addressed.

What Causes Concrete to Need Polyjacking in Gilbert?

Settlement that leads to polyjacking usually has more than one contributing cause. These are the factors most commonly found beneath settled Gilbert flatwork.

Loss of Support Beneath the Slab

When soil erodes or settles away from the underside of a slab, the concrete above it loses bearing and begins to drop or tilt. That lost support is the core problem polyjacking addresses by filling the void and re-establishing contact beneath the concrete.

Variable Soil Compaction

If the subgrade beneath a slab was not uniformly compacted before the concrete was poured, the soil can settle unevenly over time. The slab above follows, creating the elevation differences that polyjacking is used to correct.

Drainage and Erosion

Water moving along joints, edges, or downspout discharge can carry soil away from beneath a slab. Erosion removes the support under the concrete and lets the panel drop, which is why drainage is part of any polyjacking evaluation.

Changing Soil Moisture

Gilbert soil goes through wet and dry cycles driven by monsoon moisture and irrigation. As soil moisture changes, the ground beneath a slab can expand, shrink, or shift, allowing the concrete above it to settle unevenly.

Settlement at Slab Transitions

Settlement often shows up first at transitions — where a driveway meets the garage, where one sidewalk panel meets the next, or where a patio meets a walkway. These joint locations are where elevation loss becomes most visible and where polyjacking is frequently requested.

Signs Polyjacking May Be Appropriate

These are common signs that a slab may be a candidate for polyurethane foam leveling. An on-site evaluation determines whether polyjacking is actually the right fit — these symptoms are not a remote diagnosis.

One Slab Panel Has Dropped Below the Next

A visible height difference at a joint between two panels is a clear sign that the lower panel has settled. Where the lower panel is intact, polyjacking can lift it back into alignment with its neighbor.

A Driveway Has Settled Near the Garage

A driveway that has dropped at the garage approach creates a lip or an uneven drive-in transition. Settlement near the garage is one of the most common residential polyjacking requests in Gilbert.

A Sidewalk Has Developed an Uneven Transition

An uneven transition at a sidewalk joint — where foot traffic catches on a raised lip — is a sign that one panel has moved relative to the next. These transitions are trip hazards and a frequent reason owners call for sidewalk polyjacking.

A Patio or Pool Deck Has Lost Support

A patio or pool deck section that has dropped near the coping or at a corner may have lost the support beneath it. Where the deck is sound, polyjacking can fill the void and lift the section back toward the surrounding elevation.

An Intact Slab Has Settled Without Severe Deterioration

When a slab has dropped or tilted but the concrete itself is not badly cracked, fragmented, or deteriorated, it is a strong candidate for polyjacking. The intact slab can be lifted and supported rather than replaced.

Our Polyjacking Process

A clear, condition-first process keeps the project straightforward from evaluation to final walkthrough.

  1. 1

    Assess the Slab and Surrounding Grade

    The slab is inspected for settlement, voids, cracking, and how the surrounding grade, drainage, and adjacent panels relate to the concrete. This confirms the slab is a suitable candidate for polyurethane foam leveling.

  2. 2

    Plan Lift and Support Areas

    Lifting points and void areas are located so the foam targets the actual cause of the settlement. The injection pattern is planned for the slab thickness, access, and the amount of elevation that needs to be recovered.

  3. 3

    Perform Controlled Foam Leveling

    Expanding polyurethane foam is introduced through small injection openings at the planned lift points to fill voids and raise the concrete in a controlled way, with the lift monitored as the foam expands beneath the slab.

  4. 4

    Review Elevation, Transitions, and Cleanup

    The recovered elevation, panel transitions, drainage implications, and site cleanup are reviewed, and any return-to-use guidance or follow-up is explained. No hazardous DIY drilling or injection is expected of the property owner.

How Much Does Polyjacking Cost in Gilbert?

Exact price depends on the specifics of your slab and is set after an on-site evaluation. Detailed local dollar ranges are not published here because responsible pricing requires inspecting the project. These categories show what drives the cost of polyjacking.

Job typeTypical rangeWhat affects price
Single settled panelProject-specific estimateDriven by the panel size, amount of lift, void size, foam volume, access, slab condition and thickness, and the number of treatment points. A single isolated panel sits at the lower end of the range.
Multi-panel drivewayProject-specific estimateDriven by square footage and number of panels, amount of lift, void volume, foam volume, access, slab condition, number of injection locations, surrounding surfaces, and mobilization.
Sidewalk or walkway levelingProject-specific estimateDriven by the number of panels, length of the walk, lift amount, void size, access, and the relationship to adjoining surfaces and transitions.
Patio or pool deck levelingProject-specific estimateDriven by area, lift amount, void volume, injection locations, adjoining surfaces and transitions, and whether stabilization only or elevation correction is needed.
Void filling or stabilizationProject-specific estimateDriven primarily by foam volume required to fill the void, access, number of injection points, and whether a lift is also needed. Slab condition and whether replacement becomes more economical also factor in.

What is polyjacking?

Polyjacking is a concrete leveling method that injects expanding polyurethane foam through small holes in a settled slab to fill voids and produce a controlled lift. As the foam expands beneath the concrete it re-establishes support and raises the surface back toward its original elevation. The material is lightweight and the injection openings are small, which makes polyjacking useful for many residential driveways, sidewalks, patios, and pool decks.

How is polyjacking different from mudjacking?

Polyjacking uses lightweight, expanding polyurethane foam through small injection holes, while mudjacking uses a denser cementitious slurry through larger access holes. Foam adds little load to the underlying soil and typically allows a faster return to use, while mudjacking is often more economical for larger lifts. The right choice depends on slab condition, void size, access, and how much lift is needed — not on one method being universally better.

Can polyurethane foam lift a sunken driveway?

Yes, polyurethane foam can lift a sunken driveway when the driveway panels are still largely intact and the problem is settlement or a void beneath the slab. Foam is injected beneath the settled panels to fill the void and raise the concrete back toward the adjacent surface, improving the transition at the garage and the panel-to-panel slope. Badly broken or fragmented driveway panels may require replacement instead of polyjacking.

Can polyjacking be used for sidewalks and pool decks?

Yes, polyjacking is commonly used for sidewalks and pool decks because the small injection holes keep disruption to the surface minimal and the lightweight foam suits neat-finish areas. On a pool deck, foam fills voids near the coping and lifts the settled section back toward the surrounding elevation. Sidewalk or pool deck concrete that is cracked through, crumbling, or no longer sound may need replacement rather than foam lifting.

How quickly can concrete be used after polyjacking?

Polyurethane foam cures fast, which can allow the concrete to be used again quickly after polyjacking on suitable projects. The exact return-to-use timing depends on the material, the slab condition, the amount of lift, and the weather, so same-day use is not guaranteed on every job. Your crew confirms when the specific surface is ready for regular vehicle or foot traffic.

Does polyjacking fix cracks in the concrete?

Polyjacking addresses the elevation and support beneath a slab, not the cracks in the concrete surface itself. Lifting can reduce the stress and movement that contributed to cracking and can close or narrow some cracks as the slab is realigned, but it does not restore the concrete material to an uncracked condition. Badly cracked or deteriorated concrete may need replacement.

How do I know whether polyjacking is right for my slab?

Polyjacking is right for your slab when the concrete is largely intact but has settled or lost support beneath it, and the void size, access, and lift requirement suit a lightweight foam method. An on-site inspection determines whether polyjacking, mudjacking, void filling, or replacement is the best fit for the actual conditions beneath your slab.
