Stop Dealing with a Sloped or Cracked Garage Floor
A sinking garage floor can cause more problems than you think. Doors stop closing right. Cracks get worse. Water runs in the wrong direction. At RaiseRite Concrete Lifting, we level uneven garage floors using fast-expanding polyurethane foam — no demo, no concrete trucks, and no mess. Most jobs are done in a few hours, and you can park inside the same day.
Why Do Garage Floors Sink?
Most garage floor settling happens when the soil underneath starts to shift or wash away. This can happen because of water runoff, poor backfill during construction, or freeze-thaw cycles in the Midwest. Over time, the concrete slab loses support, cracks under pressure, and starts to tilt toward the center or garage door.
If your garage floor isn’t the only surface sinking, we also level driveways, walkways, steps, patios, porches, slabs, interior floors, and pool decks. You can also view all our residential concrete leveling services.

What Are the Signs You Need Garage Floor Leveling?
A garage floor that’s sinking or sloping can cause more issues than you think. Watch for these warning signs:
Floor sloping inward or away from the garage door
Cracks widening or spreading across the slab
Gaps between the garage floor and driveway
Water running toward walls or pooling in low spots
Garage doors not sealing or closing properly
Our Fix: Quick, Clean Concrete Leveling with Foam
Step 1) Injection holes are strategically drilled around the areas where the concrete is sunken and requires lifting.
Step 2) Once everything is prepped, and the hose and material are in place, the polyurethane foam is injected through the holes. It expands to fill the space underneath the concrete slab, using the slab itself to drive the foam into the crevices, thereby lifting the concrete back to its original position.
Step 3) Once the concrete is stabilized and lifted to the proper position, the injection holes are filled with new cement, allowing you to use your surface immediately.
Polyurethane concrete raising uses a foam material that is injected under the slab. When the components of the material are mixed, a reaction causes the material to expand. This expanded foam fill any voids beneath the slab and raises the concrete. This material will never lose density, is permanent and weighs only about 2 pounds per cubic foot.
