Sunken concrete slabs create uneven surfaces, drainage problems, and safety concerns around a home. Slabs can settle in garages, patios, walkways, or open areas where soil conditions change over time.
Concrete slab leveling raises settled slabs back into position without removing or replacing the concrete. Foamjection uses polyurethane concrete lifting to restore support beneath the slab and stabilize the surface.
Concrete slabs sink when the soil beneath them can no longer provide support. Common causes include:
When support is lost, slabs settle unevenly and continue to shift if the issue is not addressed.
You may need slab leveling if you notice:
Early leveling helps prevent further movement and surface damage.
If nearby concrete has also settled, driveway leveling, patio leveling, or walkway & sidewalk leveling may be needed to stabilize connected slabs and restore consistent height across the area.
Foamjection levels concrete slabs by injecting high-density polyurethane foam beneath the slab. The foam expands to fill voids, lift the concrete, and restore firm support below the surface.
Most concrete slab leveling projects are completed in one visit, and many surfaces are ready for use the same day.
Homeowners choose slab leveling because it fixes uneven concrete without the cost and disruption of replacement. Lifting restores safety, improves drainage, and keeps existing concrete in place.
For slabs that are intact but uneven, leveling is often the most practical solution.
Concrete slabs become uneven due to soil erosion, poor drainage, soil movement, and freeze-thaw cycles.
In many cases, yes. Leveling costs less, takes less time, and avoids removing existing concrete.
Most projects are completed in a single visit.
Leveling restores support under the slab. Existing cracks may remain but are often prevented from worsening.
Yes. Leveling helps restore proper slope so water drains away from the slab.
The holes are small and patched after lifting. They are much less noticeable than replacement seams.
Yes. Once cured, the foam is stable and remains below the concrete surface.
