Polyjacking in Chandler, AZ | 10+ Years Experience

Polyjacking is a concrete lifting method that uses expanding polyurethane material injected beneath settled slabs to fill voids and produce a controlled lift where the slab and void conditions support it. Chandler Concrete Leveling applies polyurethane foam injection across residential driveways, sidewalks, patios, pool decks, garage slabs, and selected commercial flatwork throughout Chandler and the East Valley. With 10+ years of experience and insured, we evaluate whether a slab is a suitable polyjacking candidate before recommending the method.

Polyurethane lifting suits many Chandler properties because the smaller injection holes and lighter expanding material work well on intact slabs that have shifted vertically due to void development, subgrade settlement, or washout. From Ocotillo and Fulton Ranch neighborhoods along Chandler Boulevard to properties near the Loop 202 Santan Freeway, settlement patterns tied to irrigation, drainage, and disturbed fill show up repeatedly. Polyjacking addresses the void beneath the slab and lifts the panel back toward the adjacent surface rather than tearing out otherwise serviceable concrete.

Chandler property owners choose us for polyurethane concrete lifting because we specialize in slab leveling, evaluate the slab before recommending a method, and monitor the lift against the surrounding elevation rather than injecting blindly.

10+ Years Experience

More than a decade evaluating and correcting settled flatwork across Chandler and the East Valley, including polyurethane lifting on residential and light commercial slabs.

Insured

Chandler Concrete Leveling is insured, so the work you hire us to perform is backed by appropriate coverage.

Concrete-Leveling Specialization

We focus on lifting and stabilizing settled slabs rather than spreading across unrelated trades or generic decorative concrete.

Method-Specific Polyjacking Knowledge

We understand how expanding polyurethane material behaves beneath a slab and when smaller injection holes are an advantage for the surface and access.

Controlled Lift and Elevation Monitoring

The lift is brought up gradually with elevation checked against the adjacent slabs, not injected in one uncontrolled movement.

Repair-vs-Replacement Honesty

When a slab is too broken or badly displaced to lift responsibly, we say so and explain why, instead of overselling a polyjacking job that will not hold up.

Transparent Pricing

You get clear planning ranges and an honest explanation of what moves the number before any work begins.

Local Chandler Settlement and Drainage Context

We recognize the irrigation, drainage, and disturbed-fill settlement patterns common to Chandler and the East Valley desert climate.

Driveway Polyjacking

Driveway polyjacking lifts sunken or tipped driveway panels where vehicle loading, disturbed fill, or subgrade settlement has left one section lower than the next. It applies to single-family and multi-panel residential driveways across Chandler, where a misaligned joint becomes both a trip edge and a drainage trap.

Small injection ports are placed through the settled driveway panel and expanding polyurethane material is injected beneath the slab to fill the void and lift the panel gradually. The foam expands to fill the open space and stabilizes the support layer, with the lift checked against the adjacent driveway panels and the garage approach.

The result is a smoother, safer driveway surface with a reduced trip hazard at the joints, improved drainage direction where the grade allows, and small patched injection points — without tearing out and repouring a slab that still has service life.

Sidewalk Polyjacking

Sidewalk polyjacking lifts settled or raised sidewalk panels that create trip hazards along front walkways, side paths, and common-area walking surfaces. It applies wherever pedestrian traffic crosses a joint that has offset enough to catch a foot or a wheel.

Injection holes are placed through the settled sidewalk panel and expanding polyurethane foam is injected beneath the slab to fill the void and raise the panel back toward the adjacent walkway. The smaller injection holes suit pedestrian slabs where a clean, minimal-footprint lift is preferred.

Property owners get a safer walking surface with a reduced trip hazard, restored joint alignment, and small patched injection points, which is usually far less disruptive than removing and repouring an entire sidewalk run.

Patio and Pool Deck Polyjacking

Patio and pool deck polyjacking lifts settled backyard patio slabs and pool deck sections where irrigation, drainage, or fill settlement has dropped one section below another. It applies to poured concrete patios and pool decking common in Chandler desert-landscaped yards, where a tipped slab collects water and becomes uneven underfoot.

The void beneath the patio or pool deck slab is identified and filled by injecting expanding polyurethane material through small ports, lifting the slab gradually while the elevation is checked against the surrounding grade, coping, or the home's edge. The smaller holes are an advantage near pool edges and tight backyard access.

The surface is restored to a more usable, better-draining area with a reduced trip edge and clean patched holes, preserving the existing finish rather than requiring a full demolition and repour — especially valuable near water where barefoot traffic makes uneven slabs risky.

Garage Slab Polyjacking

Garage slab polyjacking lifts settled garage floor sections where one part of the slab has dropped relative to the adjacent floor or the driveway approach, creating a lip and a drainage issue. It applies to attached residential garage slabs across Chandler where a tipped floor traps water and trips feet.

Small injection ports are placed through the settled garage slab and expanding polyurethane material is injected beneath the panel to fill the void and raise the section gradually. The lift is checked against the neighboring floor and the garage door threshold so the transition lines up cleanly.

The garage floor is restored toward a smoother, safer surface with a reduced step at the joints and improved drainage direction, without the cost and disruption of removing and repouring the entire slab.

Concrete Void Filling With Polyurethane

Concrete void filling with polyurethane addresses open space beneath a slab — from washout, settling fill, or erosion — that has removed support and let the surface drop. It applies under driveways, patios, garage slabs, and commercial flatwork where the void is the underlying problem.

Expanding polyurethane material is injected through ports into the void beneath the slab, filling the open space and restoring the support layer. Where the slab has already settled, the fill can also produce a controlled lift as the void closes and the foam stabilizes the subgrade.

The property owner gets a stabilized slab with restored support beneath the surface, a reduced risk of further settlement, and clean patched injection points — addressing the cause rather than only the symptom.

What Causes Concrete to Settle Before Polyjacking Is Needed?

Voids Beneath the Slab

Open space under a panel — from washout, settling fill, or erosion — removes support and lets the slab drop at that section. Polyjacking fills that void with expanding material to restore support.

Uneven or Poor Subgrade Compaction

When the soil or fill beneath a slab was not uniformly compacted before the pour, the subgrade can consolidate over time and leave a void the slab settles into.

Water Movement and Washout

Concentrated runoff, gutter downspouts, or landscape drainage can carry fine material out from under a slab, eroding the support layer and creating a void.

Irrigation and Drainage Near Concrete

Desert landscaping still uses irrigation, and leaks or overspray near flatwork can keep the subgrade wet and prone to movement or settling, especially with repeated wet/dry cycles.

What Are the Signs Polyjacking May Be Appropriate?

Uneven Slab Joints

When control joints or panel edges no longer line up and one panel sits visibly higher or lower than its neighbor, a void beneath the lower panel is a common cause.

Sunken Panels

A panel that has dropped relative to the surrounding surface — a driveway section, sidewalk run, or patio corner — is a primary candidate for controlled lifting when the slab is intact.

Trip Edges

A vertical offset at a joint that catches a foot, a wheel, or a toe is a safety issue that leveling is specifically meant to reduce by bringing the panels back into plane.

Water Collecting Toward Settled Areas

When surface drainage now runs toward a low slab instead of away from it, the settlement has changed the grade and water is pooling where it should not.

Visible Void Indications

Where safely observable, a hollow sound beneath a slab, a gap at an edge, or erosion beneath a slab apron can indicate open space that void filling addresses.

Otherwise Intact Slabs That Have Shifted Vertically

A slab that is largely intact but has shifted up or down is the ideal polyjacking candidate, because the concrete itself does not need replacement — only the support and elevation.

Our Polyjacking Process

  1. Step 1: Inspection and Elevation Measurement

    We walk the slab, check for cracking, displacement, and joint misalignment, and measure the elevation difference between the settled panel and the adjacent surface.

  2. Step 2: Identify Lift Points and Void Context

    We look for voids beneath the slab, water movement or washout patterns, and the amount of lift needed to bring the panel back toward the adjacent surface.

  3. Step 3: Prepare Small Injection Locations

    Small injection holes or ports are laid out and drilled through the slab so the expanding polyurethane material can reach the void beneath the settled panel.

  4. Step 4: Inject Expanding Polyurethane Material in Controlled Stages

    Material is injected in a controlled sequence to fill the void and produce a gradual, measured lift, with elevation checked against the surrounding slabs throughout.

  5. Step 5: Monitor Lift and Alignment

    The lift is brought up gradually and checked against the adjacent panels, joints, and grade so the surface lines up cleanly rather than overshooting.

  6. Step 6: Patch Injection Holes and Final Review

    Injection points are patched and the finished alignment, joint match, and drainage direction are reviewed before the crew leaves the site.

How Much Does Polyjacking Cost in Chandler?

The ranges below are typical market-level planning ranges for polyurethane concrete lifting in the Chandler area, not binding quotes. Polyurethane systems may price differently from cementitious mudjacking. An on-site evaluation determines the actual scope, method, and price for your slab.

Small localized foam lifting

Approximately $600–$1,500

Typically covers a single settled panel or a focused trip-hazard lift. Minimum service charges can materially affect very small repairs.

Typical sidewalk or patio multi-slab work

Approximately $900–$2,500

Covers a small group of residential panels such as a sidewalk run or patio section. Foam volume, void depth, and number of injection locations move the number.

Driveway or multiple-panel polyjacking

Approximately $1,500–$4,000+

Covers larger residential driveway and multi-panel scopes. Slab area, lift amount, and material volume are the main drivers.

Larger pool deck, garage, or void-fill work

Approximately $2,000–$6,000+

Reflects bigger slabs, deeper voids, heavier material volume, or tight access. Method and access strongly affect price.

What moves the number: foam volume, void depth, number of injection locations, slab area, amount of lift, access, and slab condition. We are not able to confirm a final price without evaluating the slab in person.

Polyjacking vs. Mudjacking: Which Is Better for Your Slab?

Neither polyjacking nor mudjacking is universally better — the right method depends on the slab, the void, the lift, the access, and the project. Polyjacking uses expanding polyurethane material injected through comparatively small holes; it is lighter, cures quickly, and suits tight access and surfaces where smaller injection points matter. Mudjacking uses a heavier cementitious slurry through larger holes; it is a long-established, cost-effective option where the slab condition suits a denser lifting material and larger openings are acceptable.

Material weight, injection-hole size, material behavior, project suitability, cost, access, lift control, and slab condition all factor into the choice. A largely intact slab with a modest void may suit polyurethane injection; a heavier panel or a scope where larger holes are acceptable may suit cementitious mudjacking. We select the method based on the specific slab rather than defaulting to one. For the cementitious method, see our mudjacking page.

Frequently Asked Questions

What is polyjacking?

Polyjacking is a concrete lifting method that uses expanding polyurethane material injected through comparatively small holes to fill voids beneath a slab and produce a controlled lift. The foam expands to fill the open space and stabilizes the support layer, leaving small patched injection points. It suits many residential and light commercial slabs where smaller holes and lighter material are an advantage.

How does polyurethane foam lift concrete?

Polyurethane foam lifts concrete by expanding beneath the settled slab to fill the void and push the panel back toward its original elevation. The material is injected through small ports, expands to fill the open space, and stabilizes the support layer, with the lift checked against the adjacent surfaces as it rises. The lift is gradual and controlled rather than a single sudden movement.

How long does polyjacking usually take?

Polyjacking usually takes a matter of hours once the crew is on site, because the lift is performed through injection rather than demolition and curing. Larger multi-slab, pool deck, or void-filling scopes take longer. We do not promise exact same-day completion for every job; timing depends on the number of slabs, the lift, and the access.

Can polyjacking lift a driveway?

Polyjacking can lift a sunken driveway when the slab remains structurally sound enough to lift. Expanding polyurethane material is injected beneath the settled panel to fill the void and raise it back toward the adjacent panels. If the driveway is severely cracked or shattered, replacement may be the more appropriate recommendation.

Can polyjacking be used around a pool deck?

Polyjacking can be used around a pool deck when the slab and access support it. The smaller injection holes and lighter material suit tight access near pool edges and coping, and the settled section is raised gradually with elevation checked against the surrounding deck. We do not perform work on pool shells, plumbing, or coping replacement.

Will polyjacking repair concrete cracks?

Polyjacking will not reliably repair existing cracks. Lifting restores alignment and can narrow some movement at a crack as the slab is brought back toward elevation, but cracks that are already part of the slab generally remain visible. Crack appearance is separate from the lift, and polyjacking is not a crack-repair or resurfacing method.

How do I know whether polyjacking or replacement makes more sense?

Polyjacking makes sense when the slab is largely intact with manageable cracking and the underlying problem is a void or settlement that lifting can address. Replacement makes more sense when the concrete is severely cracked, shattered, deteriorated, or badly displaced, or when an underlying failure needs to be rebuilt first. An honest on-site evaluation tells you which path applies to your slab.
