Polyurethane Concrete Lifting

There is a practical solution for sunken concrete...

High density polyurethane injection is a proven, effective and lasting method used to Lift, Level and Support sunken or unstable concrete slabs. By drilling small holes and pumping our engineered material under the concrete we can raise and stabilize your existing slab, typically in one day or less.  This process restores value, beauty, and safety to your property, at a cost dramatically less than replacement. 


Residential Services

"Poly Leveling" is becoming more and more popular with home owners for several reasons: smaller injection holes drilled through their concrete, ability to fully resume traffic on the repaired surface within 30 minutes, no damage to the surrounding area (lawns, flower beds, etc.).  And with our work guarantee and warranty, customers have peace of mind that the job will be done correctly and will last.

When called to assist a home owner with a free estimate they are often surprised that they can have raised and aligned concrete again, in a matter of a few hours, saving them time, money and aggravation. Raising and stabilizing concrete with polyurethane foam is inexpensive compared to the alternatives, and much faster than replacement.  From simple sidewalk leveling, to driveways, patios and pools decks, Slab Jack Concrete is here to help restore beauty and functionality.

Commercial Services

If you have a commercial building and are experiencing rocking sections in concrete slabs, trip hazards, loading dock or ramp problems, call us to arrange for a free site evaluation.  Commercial property should be functional and safe at all times.  Additionally, ADA regulations and liability exposure make it important to maintain all commercial concrete. 

Void Filling: Concrete settling is not the only problem our service can solve. Voids under slabs are often present in areas where wash out or excessive soil settling has occurred. High traffic and heavy loads are common to commercial properties so it's important to have structurally sound concrete surfaces.  By injecting high density polyurethane foam into the void, load-bearing force is generated, creating a safe and stable working surface.

Joint/Slab Stabilization: Concrete slab stabilization is often required when concrete slabs lack support, but may or may not be settled. Concrete slabs can crack when loads exceeding its capacity are applied. Slab/joint stabilization applications require the voids to be filled to eliminate movement and offer support. This type of foam is specifically designed for joint/slab stabilization applications due to its very long reaction time and minimal expansion strength. It will take longer to expand, allowing for better coverage under the slab or down a joint.

Concrete Raising for Apartment Complexes, Businesses, City Facilities, etc.
When you have uneven sidewalks, stoops, and patios, you introduce the possibility for annoyed tenants and customers, plus you have the possibility for injury and lawsuits. The American Disability Act requires that walk ways that have more than ¼” drop be repaired or replaced.  Concrete lifting and leveling is faster, causes less interruption and is much cheaper than replacement cost. 

Municipal / D.O.T. Services

Cities and municipalities have the never ending task of maintaining concrete infrastructure.  Partnering with municipalities and D.O.T. we can provide our service with minimal interruption and facilities downtime.  Concrete lifting is fast, effective and permanent.  From simple sidewalk projects to more critical roadways, bridge approaches and highways we can do the job.

Sidewalks, Playgrounds, Parks, Walking Trails, Roads, Highways, Curb and Gutter... whatever the project Slab Jack Concrete can help.


Don't Replace it, Raise it!

Homes, commercial property, and municipalities all experience sunken concrete problems:

  • Sidewalks
  • Curbs
  • Basements
  • Stairs
  • Driveways
  • Pool Decks
  • Patios
  • Floors
  • Loading docks
  • Roads
  • Bridge approaches
  • Ramps

It's important to maintain the concrete in all of those areas listed.  Deterioration can pose significant safety and potential liability issues, while diminishing property value.


Concrete replacement is expensive

The math is simple.  The cost of replacing existing concrete with new material is expensive! For example, the replacement of a simple 10’x10’ piece of driveway, walkway, or pool deck can cost upwards of $2000. Concrete contractors must make up to three trips to a location to replace a simple slab of concrete with removal of old concrete, framing new concrete forms, pouring new concrete that could require expensive concrete pumping equipment, removal of framing material and cutting relief joints. A further consideration is that newly poured concrete will not color match existing concrete, so the cosmetic trade-off is obvious. Add to this the cost and ever growing environmental problem of concrete disposal and it just makes good sense to repair it!

Be environmentally friendly, save money, and restore your property value. Don't Replace it, Raise it!


What are the possible solutions for sunken concrete?

Grinding: Inexpensive option, but not aesthetically pleasing to the eye because grinding concrete exposes the aggregate in the concrete and will no longer match the surrounding area.  The integrity and strength of the concrete slab is also compromised during this process. If the concrete continues to settle, the weak slab can no longer be raised and leveled after grinding. Excessive grinding is messy and impractical for large sections of concrete because it may limit the ability to serve its intended load-bearing function. 

Replacement: The most expensive and time consuming option to level concrete. Colors of slabs will not match and can contribute to significant downtime of the area for curing time.  Replacement does not guarantee the root issue is fixed, so it may simply be a temporary but costly solution.

Raising & Stabilizing: Lifting concrete using high density polyurethane foam can raise and support sunken concrete or unstable concrete slabs by drilling holes and pumping material under the slab. Settled concrete is commonly a result of poor soil conditions below a slab.

Remember.... Don't Replace It, Raise It!
