Garage Floor Leveling
Liftech is Colorado's Highest Rated Concrete Leveling Company REQUEST FREE ON-SITE ESTIMATE ONLINEGarage Floor Leveling
Settled garage floors can affect everyday access, drainage and garage door performance. Throughout the greater Denver metro area and the Front Range, homeowners notice garage doors that don’t seal properly, vehicle undercarriages scraping raised thresholds or water collecting near garage entries and low spots after snowmelt. Liftech lifts sunken garage floors using polyurethane injection that corrects settlement while addressing the soil conditions beneath your concrete.
Signs Your Concrete Garage Floor Needs Repair
Colorado’s expansive clay soils can shift with changes in moisture, creating voids that allow concrete to settle. Schedule an inspection if you notice:
- Doors malfunction: Your garage door sticks during operation or won’t close completely because the floor movement has thrown the opening out of alignment.
- Threshold damage: The concrete slab edge drops away from the doorway, creating a lip that scrapes your vehicle and allows water into living spaces.
- Pooling water: Low spots trap precipitation and snowmelt around parked vehicles, accelerating concrete deterioration while creating slip hazards.
- Visible cracks: Fractures develop where unsupported concrete edges bear weight that should be distributed across the full slab.
POLYURETHANE FOAM INJECTION
Liftech’s polyurethane foam injection process requires fewer holes at less than half the size of traditional mudjacking services.
The Garage Floor Leveling Process
Polyurethane Concrete Garage Floor Leveling
Polyurethane foam injection fills voids and compacts loose material, leveling the garage floor and lifting concrete slabs back to grade.
Technicians drill penny-sized holes through settled areas at approximately 4-foot intervals. They inject expanding foam beneath the concrete, filling cavities while generating lift pressure. Material cures within 15 minutes, allowing immediate vehicle traffic. Injection points receive grout patches that blend with the surrounding concrete.
Polyurethane is designed to maintain its structural integrity over time. The waterproof foam helps limit moisture movement beneath the slab and supports the repaired area to help prevent re-settlement.

Cost Savings Over Replacement
Sunken garage floor repairs typically cost less than a full replacement. Beyond direct expense savings, polyurethane injection eliminates demolition disruption, disposal fees and the weeks of garage closure that new concrete installation requires. You maintain the existing slab’s integrity while addressing underlying failures that replacement alone overlooks.
FAQ's About Garage Floor Leveling?
Once you decide you’re ready to have Liftech raise your garage floor, you may have more questions about the actual process and how the job will be completed. That is completely normal! Given that, here are questions our customers typically ask:
How long does the process take?
When you request an on-site estimate from our team, they will be able to give you an accurate estimate on how much your project will cost and how long it will take. Generally speaking, most residential projects are completed in less than a day. We are typically able to fully level your garage in the matter of a few hours or less! If the project is for a commercial or municipal project, it may take a bit longer depending on the size of the project.
How long do I have to wait to use my garage again?
Trust us, we know that not being able to use your garage is a nuisance. The technique we use is very fast and sets within minutes. By the time we clean up our site and leave your location, you will be able to use your garage floor like normal and even park your car on it!
Will my concrete move after being leveled?
The entire reason you’re hiring a concrete leveling company to repair your garage floor is to prevent costly repairs from happening in the future. While your concrete will likely move, especially in exterior environments, this is no cause for concern. The polymers that we inject do not fail, and although your concrete may still move as the soil contracts and expands, it is likely that your concrete may return to its original position once moisture returns to the soil in the fall and winter. For more additional information about this, feel free to give us a call and we’d be more than happy to chat through this process with you.
Is Polyurethane safe for the environment?
All of the components that we use here at Liftech are non-toxic and completely safe for the environment. In fact, the polyurethane we use is even safe for use in potable water!
Once the mixture is injected below your garage floor, it develops an outer skin that acts as a barrier to the reaction that will occur within the skin and it fully cures as an impermeable, solid structure.
Is the process loud?

THE ISSUE
Similar to the settling that occurs around the exterior foundation of a home when built, garages often experience the same issues from poor compaction around the garage stem walls when the concrete is poured.
THE SOLUTION
At Liftech, we know that no two homes are the same. That’s why we take the time to do an on-site inspection of your garage floors to determine the best plan of action for your project. We will only inject the necessary amount of polyurethane to successfully raise your garage floor back to its optimal height.
THE END RESULT
Generally complete within minutes to just a few hours depending on the size of your project, our team will be done injecting the eco-friendly foam. Once complete, you will be able to use your garage like normal with no down time.

Professional Evaluation
A Liftech Concrete Expert with experience in commercial building concrete assesses the extent of the concrete settlement and determines the best approach to leveling the surface.
Drill Holes
Small penny-sized holes are drilled into the sunken or uneven concrete surface. Before the crews begin injecting foam underneath the slabs, our exteprt teams will game plan for port placement to begin the lift. Liftech is strategic in chosing our injection areas to ensure a successful lift.
Injection
The material is injected as a liquid, and through a chemical reaction, it forms an expandable, completely inert, closed-cell foam. When raising concrete slabs that are very large and have differing heights, it is important to have numerous polyurethane guns injecting foam underthe slab at once to disperse the weight.
