Polyurethane Concrete Leveling

Void Filling – Using Polyurethane to Fill, Stabilize and Reinforce Open Spaces, such as: Under Concrete Slabs, Concrete Leveling, Driveways, Sidewalks, Walkways and Patios, Under Structures Both Commercial and Residential, Porches and Stairs

Dealing with Uneven, Sinking, or Trip-Hazard Concrete?

Don't Replace It, Raise It!

Polyurethane Foam Concrete Leveling in Southeastern Michigan

Trusted solutions for homeowners, commercial properties, and industrial facilities.

Concrete leveling with polyurethane foam provides a fast, reliable, and minimally disruptive solution for lifting and stabilizing sunken concrete slabs. Whether you’re dealing with uneven sidewalks, sinking driveways, or structural slab settlement, our team delivers precise repairs designed for Michigan soil conditions.


Instead of tearing out and replacing concrete, polyurethane foam injection lifts and supports existing slabs from below, restoring safety, appearance, and long-term performance with minimal downtime.

Polyurethane foam concrete leveling provides a clean, fast, and long-lasting way
to lift and stabilize uneven slabs with minimal disruption.

What Polyurethane Foam Concrete Leveling Fixes

Polyurethane concrete lifting corrects a wide range of slab settlement problems, including:

Don't Let Uneven Concrete Cause These Problems!

Why Concrete Settles

Concrete settles when the soil beneath it loses strength or support. This commonly occurs due to soil erosion, poor compaction, moisture changes, and Michigan’s freeze-thaw cycles. Over time, these conditions create underground voids that allow slabs to sink, shift, or crack.


Heavy clay soils, fluctuating groundwater levels, and surface water runoff all contribute to slab movement. Without proper stabilization, settlement can worsen and spread to adjacent concrete sections. This is especially common in Southeastern Michigan where clay-heavy soils and freeze–thaw cycles accelerate settlement.

How Our Polyurethane Concrete Leveling Works

Our polyurethane concrete leveling process lifts and stabilizes concrete by injecting expanding foam beneath the slab to fill voids and restore support. The process is fast, controlled, and typically completed in a single visit.


The Process:

  1. Small injection ports are drilled into the concrete surface
  2. Expanding polyurethane foam is injected beneath the slab
  3. The foam fills voids, compacts soil, and lifts the slab
  4. The injection points are patched and the area is ready for use the same day


Technical Benefits:

  • Strengthens weak or eroded soils
  • Forms a closed-cell, water-resistant base
  • Improves load-bearing performance
  • Lightweight material that won’t overburden soil
  • Cures quickly compared to traditional mudjacking
  • NSF/ANSI 61 certified for contact with potable water
  • Suitable for residential, commercial, and industrial slabs

Applications for Residential, Commercial, and Industrial Properties

Polyurethane concrete leveling is a versatile, non-invasive solution used across residential, commercial, and industrial environments to correct settlement, restore safety, and stabilize concrete slabs.

Residential Applications


Common residential concrete leveling projects include:


  • Settled driveways & walkways
  • Uneven patios & porches
  • Sinking garage floors 
  • Unlevel pool decks

Commercial Applications


Concrete leveling solutions commonly used for commercial properties:


  • Settled warehouse floors
  • Uneven storefront & shared sidewalks
  • Unlevel retail & office slabs
  • ADA trip-hazard corrections

Industrial  Applications


Polyurethane foam leveling is also used for infrastructure and heavy-load environments such as:


  • Settled utility access slabs
  • Heavy-load slab stabilization
  • Uneven roadway & approach slabs
  • Public sidewalk systems

Frequently Asked Questions

How long does the process take?

Most concrete leveling projects take less than a few hours and can be walked or driven on the same day.

Will this fix my concrete permanently?

Polyurethane foam is long-lasting and resistant to water and soil movement. Longevity depends on underlying soil conditions, but the repair itself is durable and stable.

Is polyurethane foam safe?

Yes. We use NSF/ANSI 61–certified foam that's safe for contact with soil and potable water, making it ideal for both interior and exterior work.

Is this better than mudjacking?

Yes. Polyurethane is lighter, stronger, waterproof, and far less invasive. It provides a longer-lasting and more precise lift.

Concrete Leveling Glossary​
Heave / Frost Heave:

Upward movement of concrete caused by soil expansion, frost, or tree roots.

Downward movement of slabs due to erosion, moisture changes, or poor compaction.

Adjusting the angle of concrete for proper drainage.

Empty spaces under slabs caused by erosion or soil washout. Foam injection fills and stabilizes these areas.

Sideways shifting of concrete slabs. Our technicians evaluate this when determining how to stabilize adjacent slabs.

Allowing Materials to Reach Full Strength. Mudjacking Takes 24 Hours, While Polyurethane Foam Cures Within Hours.

Applying Sealant to Protect Concrete from Moisture Penetration.

A Deliberate Gap Between Slabs to Allow for Movement Due to Temperature Changes. Sealing These Is Crucial.

Lifting Concrete with a Slurry Mixture. This Method May Require Repeated Applications Due to Potential for Re-Settlement.

A Reliable and Long-Lasting Solution for Lifting and Leveling Concrete Using Polyurethane Foam. It Addresses Voids and Is More Cost-Effective Than Replacement.
