See how TerraFirma uses polyurethane concrete lifting technology on a roadway application and why the same underlying approach can also be used to lift and stabilize residential concrete.
Concrete Lifting Built for Demanding Surfaces
Sunken or uneven concrete can create safety concerns and disrupt how a surface is used. TerraFirma’s concrete leveling approach uses high-density polyurethane foam to fill voids beneath a slab and help lift and stabilize the concrete.
The Interstate 5 repair featured in this video demonstrates the scale of work polyurethane lifting can support. For homeowners, the same type of technology is used on common surfaces such as sidewalks, driveways, patios, garage slabs, and walkways.

The video shows how polyurethane concrete lifting can be used on a high-demand roadway surface. The same core technology is also used by TerraFirma to address uneven residential concrete where conditions are appropriate.
HOW IT WORKS
What Polyurethane Concrete Lifting Does Beneath the Slab
01
Access the Slab
Small injection points provide access beneath the concrete without requiring the entire slab to be removed.
02
Fill Voids
High-density polyurethane expands beneath the slab, filling voids that can contribute to sinking or instability.
03
Lift and Stabilize
As the material expands, trained installers can control the lift and help return the slab toward the intended position.
FROM HIGHWAY TO HOME
Where Concrete Leveling Can Help Around Your Property
Sidewalks
Uneven sidewalk slabs can create noticeable height differences and tripping hazards around a home.
Driveways
Sunken driveway slabs can create uneven transitions and may continue to shift when voids remain beneath the concrete.
Patios & Garage Slabs
Leveling may be appropriate when an otherwise serviceable slab has settled and needs support beneath it.
Why Repair Instead of Automatically Replacing?
When the concrete slab itself is still suitable for repair, lifting can address settlement without immediately tearing out and replacing the entire surface.
Benefits of PolyLevel Concrete Lifting
- Non-invasive installation: compact injection equipment can reach areas that larger equipment may struggle to access.
- Fast cure time: TerraFirma’s current concrete repair guidance notes that full loading can usually happen about 15 minutes after injection.
- Adjustable lift: trained installers can fine-tune the lifting reaction based on slab weight, soil characteristics and jobsite conditions.
- Lightweight material: the polyurethane foam adds substantially less weight than standard fill materials.
Uneven Concrete Around Your Home?
If your sidewalk, driveway, patio, walkway, or garage slab has settled, TerraFirma can evaluate the concrete and determine whether lifting and repair are appropriate for the property.

HOMEOWNER QUESTIONS
How does the warranty work?
For concrete slabs raised with TerraFirma’s PolyLevel®, we guarantee that the area where the slab of concrete was lifted will not settle more than ¼ inch for a period of 5 years from the date of installation. If it does, we will provide the labor and materials to re-level the area at no additional charge.
What is better: mudjacking or polyurethane?
A Polyurethane solution is not as messy or disruptive as other foundation-lifting techniques like mudjacking. Our PolyLevel solution is lightweight (without compromising strength), offers faster installation and cure time, making it the best option available.
What kind of foam is used to lift concrete?
High-density polyurethane foam is the expert’s choice for concrete lift. Our PolyLevel solution uses a high-density polyurethane foam to fill voids and stabilize sinking concrete slabs. The expanding properties of the two-part urethane formula allows for the lifting of the slab.
Can you repair cracked concrete after going through concrete leveling?
Yes. In fact, we recommend that our TerraFirma Concrete Leveling customers seal the cracks and joints of their newly lifted concrete with our NexusPro solution, as it will help protect their concrete for many years to come.
My concrete seems to have settled over the winter. What should I do?
Your concrete most likely didn’t settle, but instead the adjacent concrete slabs heaved upwards, due to the frozen dirt below. There is nothing that can be done, but wait for the ground to thaw and the concrete to return to its original position. If the concrete doesn’t return to its normal position in the spring, you may want to have one of our experts take a look to determine if a permanent solution is necessary.
