Polyurethane Slab Lifting

Polyurethane Concrete Leveling & Slab Stabilization

Ghost Concrete Leveling lifts and stabilizes eligible driveways, sidewalks, walkways, patios, pool decks, garage floors, commercial concrete and other accessible slabs that have settled or lost support.

Our core service uses expanding polyurethane beneath the concrete to fill accessible voids, rebuild support and make controlled improvements to slab alignment without automatically demolishing and replacing the entire section.

What Concrete Leveling Actually Does

A concrete slab is only as stable as the material beneath it. When soil shrinks, fill loses compaction, water removes supporting material or an empty space develops beneath the slab, the concrete may settle, rock, separate from adjoining sections or develop an abrupt height difference.

Concrete leveling addresses the lost support beneath eligible slabs. Small injection points are placed through the concrete so polyurethane can reach accessible voids. As the material expands, it supports the underside of the slab and allows the technician to make measured adjustments to its position.

The objective is not to disguise old concrete or promise a perfectly new appearance. The objective is to restore support, reduce uneven transitions and improve the function of concrete that remains suitable for lifting.

Problems That Can Lead to Settled or Unsupported Concrete

Soil Shrinkage

Dry conditions and changing moisture levels can reduce soil volume and leave portions of a slab without consistent support.

Erosion or Washout

Water moving beside or beneath concrete can carry away soil and create open spaces under slab edges or interior sections.

Poorly Compacted Fill

Fill material placed before construction can settle over time when it was not compacted evenly or has changed beneath the slab.

Drainage Conditions

Downspouts, irrigation, grading and concentrated runoff may repeatedly introduce water near the same section of concrete.

Plumbing or Water Leaks

A leak can contribute to soil movement or erosion. Active leaks must be addressed separately from the lifting work.

Tree and Landscape Activity

Root growth, root decay and landscaping changes can influence the support conditions around sidewalks, patios and other slabs.

Concrete Leveling Services by Surface

Each surface has different joints, loads, access conditions and surrounding structures. Select the service that best matches the affected concrete.

Driveway Leveling

Settled driveway panels, uneven control joints, low areas and rough transitions where the driveway meets the garage.

Our Polyurethane Concrete-Leveling Process

1

Inspect the Concrete and Surroundings

We review the slab condition, settlement pattern, cracks, control joints, adjoining structures, drainage observations and equipment access.

2

Define the Repair Objective

The project is planned around the required support, the desired alignment and the limits created by the existing concrete.

3

Plan Injection Locations

Small access points are selected so the polyurethane can reach the accessible voids and unsupported zones beneath the slab.

4

Inject, Monitor and Adjust

Polyurethane is introduced in controlled stages while slab movement, joints and surrounding surfaces are continually observed.

5

Restore Support

Material fills accessible empty space beneath the concrete and rebuilds support under the treated portion of the slab.

6

Patch and Review

Injection points are patched and the completed area is reviewed before the project is closed.

Leveling, Stabilization or Replacement?

Not every concrete problem should receive the same recommendation. The condition of the slab and the cause of movement determine whether lifting is appropriate.

Project Condition Possible Direction Important Consideration
Generally intact concrete that has settled Concrete leveling The slab must have usable integrity and a practical path for controlled movement.
Concrete with accessible voids but little desired movement Void filling or stabilization The primary goal may be rebuilding support rather than changing elevation.
Uneven adjoining slabs or a dropped transition Leveling and stabilization The final position is limited by joints, cracks, structures and surrounding concrete.
Severely broken, crumbling or structurally unsound concrete Replacement may be more appropriate Lifting cannot restore material that no longer has adequate integrity.
Settlement related to an active leak, erosion or failed drainage Correct the underlying issue and evaluate the slab Concrete lifting does not repair plumbing, drainage or grading failures.

What Concrete Leveling Can—and Cannot—Change

What It May Improve

  • Support beneath eligible concrete
  • Uneven slab-to-slab transitions
  • Low sections caused by settlement
  • Movement associated with accessible voids
  • Function of a repairable concrete surface

What It Does Not Automatically Fix

  • Existing cracks, stains or surface wear
  • Failed drains, plumbing leaks or active erosion
  • Broad property-grading problems
  • Severely deteriorated or crumbling concrete
  • Every cosmetic difference between adjoining slabs

Concrete that has been lifted will still look like the original concrete. Control joints, prior cracks, patched injection points, stains, texture differences and normal wear may remain visible.

What Determines Concrete-Leveling Cost?

Concrete leveling is evaluated by project conditions rather than by a single universal price per slab. Material requirements and access can vary substantially between two areas that appear similar from the surface.

Primary Pricing Variables

  • Number and size of affected slabs
  • Amount and pattern of settlement
  • Depth and extent of accessible voids
  • Concrete thickness and current condition
  • Polyurethane material required
  • Hose, equipment and property access
  • Residential or commercial project requirements

What to Send for a Faster Review

  • Complete project address
  • Wide photograph of the entire affected area
  • Close photographs of joints and height differences
  • Approximate slab dimensions
  • Water, drainage or leak observations
  • When the movement was first noticed
  • Gate, parking or access instructions

Concrete Leveling Frequently Asked Questions

What is the difference between concrete leveling and slab stabilization?

Concrete leveling focuses on improving slab elevation or alignment. Stabilization focuses on restoring support beneath the concrete. A project may require one or both.

Can every sunken concrete slab be lifted?

No. The slab must be evaluated for concrete integrity, access, settlement pattern, adjoining structures and the conditions that caused the loss of support.

Will the original cracks disappear after lifting?

No. Existing cracks, control joints, stains and surface wear generally remain visible. Lifting addresses support and alignment rather than making old concrete look newly poured.

Can polyurethane be used to fill a void without raising the slab?

Some projects primarily require support beneath the concrete rather than a substantial elevation change. The slab and accessible void must be evaluated before stabilization is recommended.

Does concrete leveling repair drainage or plumbing problems?

No. Lifting may improve the position of an eligible slab, but active leaks, failed drainage, erosion and broader grading problems require separate correction.

What types of concrete does Ghost evaluate?

Ghost evaluates eligible driveways, sidewalks, walkways, patios, pool decks, garage floors, commercial concrete and other accessible slabs.

What is the fastest way to request an evaluation?

Send the full project address, wide and close photographs, approximate dimensions and a short explanation of the settlement through the contact page. You may also call (832) 447-6299.
