Garage Floor Concrete Lifting Specialists
Olympic Concrete Lifting provides professional garage floor concrete lifting and stabilization for sunken, uneven, and unsupported residential slabs throughout the Kansas City area.
When soil beneath a garage floor settles, washes away, or develops hidden voids, portions of the slab can begin to sink or shift. Polyjacking can often restore support and carefully raise qualifying concrete while preserving the floor already in place.
Restore a Level, Supported Garage Floor
Garage floors experience daily vehicle traffic, changing temperatures, moisture, and repeated loads. Even when the concrete itself remains in good condition, movement beneath the slab can create low areas, uneven transitions, cracks, or gaps near the garage door.
Concrete leveling & polyjacking works beneath the existing floor by injecting expanding polyurethane foam into areas where support has been lost. The foam fills voids, stabilizes the concrete, and can carefully raise settled sections toward their proper elevation.
Where the slab has lost support but has not significantly moved, void filling may be used primarily to stabilize the floor.
Signs Your Garage Floor May Be Settling
Why Garage Floor Settlement Matters
A garage floor is more than a place to park. It connects the home, garage door, driveway, walls, and other surfaces within a relatively small area.
When the slab settles, those relationships can change. A low section near the door may create an awkward transition to the driveway, while interior settlement can lead to uneven areas beneath vehicles, storage, or workspaces.
Olympic Concrete Lifting evaluates the floor together with the garage opening, surrounding slabs, drainage, and visible cracking before determining whether lifting is appropriate.
Benefits of Garage Floor Leveling
When the existing concrete remains structurally sound, garage floor lifting can address settlement without the mess and disruption of tearing out a large interior slab. Polyurethane foam allows Olympic Concrete Lifting to work beneath the floor while keeping most of the existing concrete intact.
Restore Slab Support
Expanding polyurethane foam fills empty spaces beneath the garage floor and restores support where material has settled or eroded.
Correct Uneven Areas
Qualifying portions of the slab can be carefully raised toward the surrounding floor elevation.
Preserve Existing Concrete
A settled garage floor does not automatically need replacement when the concrete itself is still in good condition.
Improve Door Transitions
Correcting settlement near the garage opening can improve the relationship between the floor, threshold, and adjoining driveway.
Limit Interior Demolition
Small injection points can avoid the debris and disruption involved with removing large sections of concrete inside the garage.
Fast Cure Time
Polyurethane foam cures quickly, helping reduce the downtime associated with traditional concrete replacement.
Garage Floor vs. Driveway Settlement
The Two Surfaces Can Move Differently
A garage floor and driveway may meet at the same opening, but they are separate slabs and can settle independently.
Garage Floor Settlement
The interior slab may develop low spots or sink near the door while the driveway remains relatively stable.
Driveway Settlement
The exterior slab may drop away from the garage and create a noticeable lip or transition at the opening.
Sometimes both surfaces have moved. Olympic Concrete Lifting can evaluate each slab separately and determine whether the garage floor, driveway lifting, or both need attention.
What Causes Garage Floors to Sink?
Garage floors can settle even though they are inside the home.
Poorly compacted fill beneath the original slab may compress over time. Water entering around the garage, drainage near the driveway, or roof runoff discharged too close to the structure can also affect the supporting material beneath the floor. Where roof runoff is contributing to the problem, Downspout Extensions can help move water farther from vulnerable areas.
Voids may develop underneath the slab before a major elevation change becomes visible. In those situations, void filling may restore support and help stabilize the concrete before additional movement develops.
Our Garage Floor Lifting Process
Evaluate the Floor
We inspect the garage slab, visible settlement, cracks, door transition, adjoining driveway, and signs that support has been lost.
Plan the Correction
Injection locations and the amount of stabilization or lifting are determined based on the slab and surrounding elevations.
Inject Polyurethane Foam
Small holes are created in selected areas so expanding foam can reach voids beneath the floor.
Lift & Stabilize
The polyurethane fills empty spaces, restores support, and carefully raises qualifying areas where elevation correction is needed.
Garage Floor Lifting vs. Replacement
Lift the Existing Floor
When the slab remains structurally sound, polyjacking can address settlement from underneath while preserving the existing concrete.
Replace the Concrete
Floors that are severely fractured, deteriorated, extensively damaged, or otherwise unsuitable may need to be removed and repoured.
For homeowners, preserving a usable slab can reduce demolition, debris, and the amount of time the garage is unavailable.
When the Garage Floor Needs More Than Lifting
Settlement is not always the only issue.
A garage floor may also have cracks, damaged joints, worn edges, or surface deterioration that lifting alone will not correct. Olympic Concrete Lifting can combine leveling with concrete repair where the floor needs additional restoration.
If joints around the slab have deteriorated, joint sealing may also help create a cleaner finished surface once elevation issues have been addressed.
Nearby Driveway Lifting or Residential Walkway Lifting needs can also be evaluated during the same project.
Garage Floor Concrete Lifting FAQs
What causes a garage floor to sink?
Garage floors can settle because of soil compression, poor compaction, moisture movement, erosion, or voids beneath the slab.
Can a sunken garage floor be lifted?
Often, yes. If the concrete remains structurally sound, concrete leveling & polyjacking may be able to restore support and carefully raise settled areas.
Can you fill voids without raising the garage floor?
Yes. If support has been lost but the slab is still close to the correct elevation, void filling may be used primarily for stabilization.
Can lifting fix a gap between the garage floor and driveway?
If the gap or elevation difference is caused by settlement, lifting one or both slabs may improve the transition. The garage floor and driveway should be evaluated separately.
Can cracked garage floors still be lifted?
Minor cracking does not automatically prevent lifting. More significant damage may also require concrete repair or replacement.
Can polyjacking help with water collecting on the garage floor?
If settlement has created a low spot, correcting the slab elevation may help improve the surface slope. Other drainage conditions may also need to be considered.
Can the driveway be lifted at the same time?
Yes. If the exterior slab has also settled, driveway lifting can be evaluated as part of the same project.
Is garage floor lifting less disruptive than replacement?
Generally, yes. Polyjacking requires small injection points and avoids much of the demolition, removal, repouring, and curing involved with replacing the entire slab.
