Concrete slab lifting describes the outcome of raising settled concrete, not one single material. Depending on the project conditions, polyurethane foam or a traditional cementitious slurry-based method may be appropriate — and the choice depends on slab condition, the settlement pattern, access, the size of any void, how much elevation needs to be recovered, and the surrounding surfaces and drainage. Applications include driveway panels, sidewalks, patio slabs, pool decks, walkways, garage approaches, and selected other slabs that have dropped, tilted, or lost support but are still serviceable. The slab itself must be suitable for lifting: the objective is controlled elevation and support recovery, not forcing cracked or deteriorated concrete into an unrealistic position. See our concrete leveling methods comparison for how the materials differ.

The intent of this page is distinct from our polyjacking and mudjacking pages. Polyjacking is one specific slab lifting method that uses expanding polyurethane foam; mudjacking is another specific method that uses a cementitious slurry. Slab lifting is the broader outcome those methods achieve — raising a settled slab — and it is also the right framing when a property owner knows the concrete has dropped but has not yet settled on a material. Underlying voids and support conditions and the adjacent elevations matter because the lift must improve transitions and surface slope rather than create new problems. Severe deterioration can make replacement more appropriate, and slab lifting is distinct from structural foundation repair. With 10+ years of experience and insured service, Gilbert Concrete Leveling evaluates the slab first and recommends the lifting method that fits the actual conditions beneath it.

Why Choose Gilbert Concrete Leveling for Concrete Slab Lifting?

Slab lifting is an outcome, and more than one method can achieve it. Our role is to inspect the concrete first and recommend the lifting approach that fits the slab, the void, and the access.

  • 10+ Years of Experience

    A decade of raising settled slabs across Gilbert driveways, sidewalks, patios, pool decks, and garage approaches using the method each project requires.

  • Insured

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

  • Multiple Lifting Methods

    We select between polyurethane foam, mudjacking, and void filling based on what your slab and soil require, rather than recommending one method for every job.

  • Condition-First Evaluation

    The slab is inspected for condition before any method is recommended, because lifting only works on concrete that is intact enough to be raised as a unit.

  • Support and Elevation Treated Separately

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

  • Repair-vs-Replacement Guidance

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

  • Gilbert Exterior-Flatwork Familiarity

    Experience with local heat exposure, soil moisture, drainage, and monsoon conditions that affect how exterior slabs settle here.

  • Clear Estimates and Process

    Pricing is explained by the factors that drive it — slab dimensions, settlement, void volume, method, and access — and the process is laid out plainly.

Concrete Slabs We Lift and Level in Gilbert

Each application below lifts a specific type of settled concrete slab where the concrete is still sound enough to raise.

Concrete driveway slab transition with a visible height offset between panels

Driveway Slab Lifting

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

A lifting material — polyurethane foam or a cementitious slurry — is introduced at lift points beneath the settled panels to fill the void and raise the concrete, 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, preserving the existing concrete instead of replacing it.

Concrete sidewalk panels with an uneven elevation transition at the joint

Sidewalk Slab Lifting

Sidewalk slab lifting raises 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.

A lifting material is introduced beneath the lower panel to fill the void and raise the concrete back into alignment, restoring an even joint line and a continuous walking surface.

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

Settled backyard patio slab with a sunken corner in an Arizona yard

Patio Slab Lifting

Patio slab lifting corrects a patio slab that has settled at a corner or edge, creating a tilted surface, a gap beneath the slab, or a low spot that holds water. It applies to patios that are intact but have dropped or lost support.

A lifting material is introduced beneath the settled area to fill the void and bring the patio back toward level, with attention to how the surface drains away from the home and the transitions to doors and walkways.

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

Settled pool deck slab near the coping of an Arizona backyard pool

Pool Deck Slab Lifting

Pool deck slab lifting 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.

A lifting material is placed beneath the settled section to fill voids and lift the deck back toward the coping and adjacent slabs, with the deck condition 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.

Garage approach slab with a settled transition to the driveway

Garage Approach and Entry Slab Lifting

Garage approach and entry slab lifting addresses a settled slab where the driveway meets the garage floor or at an entry landing, where a dropped slab creates a transition lip and an uneven surface. It applies where the approach or entry slab is intact but has lost elevation.

A lifting material is introduced beneath the settled approach or entry slab to fill the void and recover elevation, with attention to the transition into the garage and the surface slope. This is slab leveling for the approach, not repair of the home's structural foundation.

The outcome is a smoother transition at the garage or entry with improved support beneath the slab, where leveling is technically appropriate for the condition present.

Void Filling and Slab Stabilization

Void filling and slab stabilization address 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.

Material 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.

Why Do Concrete Slabs Sink or Lose Support?

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

Variable Compaction Beneath the Concrete

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 slab lifting is used to correct.

Water Movement 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 slab lifting 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.

Voids Beneath the Slab

A void is the open space that forms when soil erodes or settles away from the bottom of the slab. Once a void exists, the concrete above it loses support and can crack or settle. Slab lifting material fills that void and restores bearing.

Settlement at Adjoining Surfaces

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 slab lifting is frequently requested.

Signs a Concrete Slab May Need Lifting

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

Slab Edge Below Adjoining Panel

A visible height difference where one slab edge sits below the adjoining panel is a clear sign of settlement. Where the lower slab is intact, lifting can raise it back into alignment with its neighbor.

Garage or Driveway Transition

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 slab lifting requests in Gilbert.

Sidewalk Trip 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 slab lifting.

Water Pooling in a Newly Low Area

When a slab settles and creates a low spot, water collects in the depression instead of draining away. Standing water on a driveway, patio, or pool deck is often a sign that the surface slope has changed and the slab may need lifting.

Intact Slab With Visible Settlement

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

Signs of Lost Support

A slab that sounds hollow when tapped, or that shows cracking consistent with lost support beneath it, may have a void underneath. Void filling and stabilization address that lost support before the surface drops further.

Our Concrete Slab Lifting Process

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

  1. 1

    Evaluate the Concrete Condition

    The slab is inspected for settlement, voids, cracking, and overall condition to confirm it is intact enough to be lifted as a unit.

  2. 2

    Measure the Settlement and Transitions

    The surrounding grade, drainage, and adjacent panel elevations are reviewed alongside the likely void areas so the repair targets the actual cause of the settlement.

  3. 3

    Select the Appropriate Lifting or Stabilization Method

    Based on slab condition, void size, access, and the lift required, a method — polyurethane foam, mudjacking, or void filling — is selected, or replacement is recommended if the concrete is unsuitable for lifting.

  4. 4

    Perform Controlled Elevation Correction

    Lifting material is introduced at the identified points to fill voids and raise the concrete in a controlled way, with the lift monitored as the material works beneath the slab.

  5. 5

    Review the Finished Slab and Next Steps

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

How Much Does Concrete Slab Lifting 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 slab lifting.

Job typeTypical rangeWhat affects price
Isolated slab or panelProject-specific estimateDriven by the slab dimensions, settlement amount, void volume, material method, access, slab condition, and the number of treatment or lift points. A single isolated panel sits at the lower end of the range.
Driveway slab liftingProject-specific estimateDriven by square footage and number of panels, amount of lift, void volume, material volume, access, slab condition, adjoining elevations, and the method selected.
Sidewalk or walkwayProject-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 slabProject-specific estimateDriven by area, lift amount, void volume, injection locations, adjoining surfaces and transitions, drainage, and whether stabilization only or elevation correction is needed.
Void filling or stabilizationProject-specific estimateDriven primarily by material volume required to fill the void, access, number of injection points, mobilization, and whether a lift is also needed. Slab condition and whether replacement becomes more economical also factor in.

When Should a Slab Be Lifted Instead of Replaced?

Lifting is commonly worth considering when the slab remains substantially intact but has settled; replacement becomes more appropriate when the concrete itself is severely deteriorated or cannot be repositioned responsibly. The decision turns on the condition of the concrete material, not just the elevation.

Cracking severity matters: a slab with minor surface cracking that has settled is often a good lifting candidate, while a slab that is fragmented, extensively cracked, or deteriorated cannot be reliably raised as a unit. Surface deterioration, the structural condition of the concrete, the existing slope, and the relationship to adjoining surfaces all factor in. When the concrete is sound, lifting preserves the existing slab and avoids the cost and disruption of demolition and repouring. When the concrete has failed, replacement is the more appropriate and more economical investment.

An honest inspection weighs the cracking, fragmentation, surface deterioration, structural condition, existing slope, adjoining surfaces, and the cost comparison between lifting and replacement — then recommends the path that makes the most sense for the specific slab.

What is concrete slab lifting?

Concrete slab lifting is the act of raising a settled concrete slab back toward its original elevation by introducing a lifting material beneath it. Depending on the project, that material may be expanding polyurethane foam or a cementitious mudjacking slurry. Slab lifting applies to driveways, sidewalks, patios, pool decks, walkways, garage approaches, and other slabs that have dropped but are still serviceable.

Is slab lifting the same as polyjacking?

No, slab lifting is not the same as polyjacking. Slab lifting describes the outcome of raising a settled slab, while polyjacking is one specific method that uses polyurethane foam to achieve that lift. Slab lifting can also be performed with a cementitious mudjacking slurry or with void filling, so polyjacking is one technique within slab lifting rather than a separate service.

Can a driveway slab be lifted?

Yes, a driveway slab can be lifted when the panel is still largely intact and the problem is settlement or a void beneath it. Lifting material is introduced beneath the settled panel to fill the void and raise the concrete back toward the adjacent surface, improving the transition and slope. Badly broken or fragmented driveway panels may require replacement instead of lifting.

Can pool decks and patios be lifted?

Yes, settled pool decks and patios can be lifted where the slab is largely intact and has lost elevation or support. Lifting material is placed beneath the settled section to fill the void and bring the surface back toward the surrounding elevation, with attention to drainage and transitions. Pool deck or patio concrete that is cracked through or crumbling may need replacement instead.

Does slab lifting fill voids beneath the concrete?

Yes, slab lifting fills voids beneath the concrete because the lifting material is introduced under the slab to occupy the open space where soil has eroded or settled away. The material re-establishes bearing under the concrete while also providing the lifting force. Filling the void and raising the slab are related but not always identical objectives — sometimes stabilization is the goal rather than significant lift.

When is a slab too damaged to lift?

A slab is too damaged to lift when the concrete itself is severely cracked, badly fragmented, extensively deteriorated, or no longer structurally sound. Slab lifting relies on the concrete being intact enough to be raised as a unit; unsound material cannot be reliably repositioned into a lasting, usable surface. In those cases replacement is the more appropriate path.
