Your Trusted Partner for Concrete Lifting, Leveling & Void Filling
Your Questions Answered
How much does concrete raising cost?
Concrete raising typically costs about half as much as replacing the same concrete. The total cost of raising or stabilizing concrete depends on the amount of leveling material required for the project. On average, concrete raising costs range between $2 and $5 per square foot. For instance, raising a 10 ft. x 10 ft. section (100 square feet) would cost between $200 and $500. Factors such as how far the slab has settled, the presence of voids, or the need to involve other sections in the repair can influence the final cost. To ensure accuracy, we offer FREE estimates. Our experienced team will visit your home or business to assess your project and provide a precise estimate tailored to your specific needs.
What kind of material do you use to raise concrete?
Polyurethane foam is injected as a liquid and sets into a rigid foam that will NEVER lose density or shrink. This lightweight material is more efficient than traditional mudjacking, requiring fewer and smaller holes for installation—resulting in a nearly invisible repair.
Will there be heavy trucks on my lawn?
Level Pro’s trucks stay parked on the street while the repair crew brings the equipment to the site needing repair. For polyurethane repairs, the process is even more lawn-friendly. A hose is run directly from the truck or trailer to the repair site, eliminating the need to drive any equipment on your lawn.
How do you fill the holes?
For polyurethane foam repairs (FoamJacking), foam plugs are not needed. The foam material used to raise the slab doubles as a built-in shock absorber, providing the same protection without the need for additional plugs.
Is there any maintenance needed?
After our work is complete, it’s your responsibility to take steps to preserve the repaired concrete. This includes caulking the seams of the repaired sections or backfilling any exposed areas to contain the material and prevent future sinking. Self-leveling cement caulk, readily available at home improvement stores, is ideal for sealing joints. We recommend using a silicone-based, self-leveling caulk for the best results. For larger cracks, you can reduce caulk usage by first filling the crack with sand and then applying the caulk on top. Preventing water from seeping under the slab is crucial to maintaining the repair. Ensure that downspouts are properly positioned to direct water away from your concrete slabs or foundation. Following these maintenance steps is a condition of your Level Pro warranty and will help ensure the longevity of your raised concrete.
What concrete can be raised/repaired?
Solid concrete slabs can be raised and stabilized effectively. However, gravel areas or blacktop surfaces cannot be repaired and must be replaced or re-installed to address settling issues. Additionally, slabs that are severely cracked may be too damaged to lift.
We Lift It All!
Sidewalks, driveways, pool decks, footings, patios, garage floors, basement floors, office floors, warehouse floors, highways, bridge approaches, seawalls, and voids can all be raised and repaired. If you’re unsure whether your concrete can be raised, give us a call for a FREE estimate. Raising settled concrete is often half the cost of replacement, with less disruption to your landscaping and minimal downtime. Our experienced estimators will assess your project and provide an accurate, no-obligation estimate to get you started.
What is the difference between Mudjacking and Polyurethane Concrete Raising?
Concrete Lifting Methods: Mudjacking vs. Polyurethane
Both mudjacking and polyurethane concrete raising effectively lift and stabilize sunken or unstable concrete slabs by drilling holes and pumping material beneath them. However, the materials and techniques used differ significantly.
Material
Concrete settlement often results from poor soil conditions beneath the slab. Polyurethane has become a preferred repair method due to its lightweight nature, which minimizes additional stress on already weak soil.
Mudjacking uses a sand-based slurry infused with Portland cement. This dense material, weighing approximately 100 lbs per cubic foot, is hydraulically pumped under the slab to fill voids and raise the concrete.
Polyurethane Concrete Raising utilizes a lightweight foam material that expands when mixed. This foam fills voids and raises the slab, weighing only about 2 lbs per cubic foot. It is permanent, will never lose density, and is ideal for maintaining soil stability beneath the slab.
Hole Size
The only visible sign of concrete repair is the holes drilled during the process.
Mudjacking requires a series of 1″ holes to inject the slurry.
Polyurethane Concrete Raising drills smaller 3/8″ or 5/8″ holes, which are nearly invisible. This method also requires significantly fewer holes than mudjacking, adding to its appeal.
Cost and Value
Concrete raising is generally half the cost of replacing a slab. However, the presence of large voids may increase repair costs. While polyurethane material is more expensive than mudjacking slurry, the benefits—smaller holes, lighter material, and fewer injection points—make it a worthwhile investment.
With our services, we’ve saved customers over $20 million compared to the cost of concrete replacement.
Do you offer a warranty?
All concrete lifting work comes with a 5-year warranty.
Cost Benefits of Concrete Raising vs. Concrete Replacement
Reduction in Labor & Service Costs
One of the main benefits of concrete raising compared to concrete replacement, is the reduction in cost you get to enjoy. To replace a concrete slab, you must hire a crew to demolish the slab, remove and discard it, stabilize the foundation below where it used to be, repour and let cure the new cement.
Minimal Impact on Surroundings
When replacing a slab of concrete, you must use (often large and heavy) equipment to demolish and re-pour the slab. This may force you to move / reorganize your warehouse or factory, or damage the landscape that surrounds the slab.
Minimize Potential for Injury
Whether you own a commercial building, or a tenant-occupied residence, the potential for injury greatly increases when you have uneven or compromised concrete slabs on your property. Replacing concrete slabs can be a multi-day, or sometimes even multi-week period, which again, presents the possibility for your workers, tenants or passerby’s to fall subject to injury.
