Uneven concrete floors in a home, shop, or other building can create safety concerns and ongoing issues. Settling can lead to trip hazards, cracks across the surface, and low spots where moisture can collect. These problems often worsen over time as the soil beneath the slab continues to shift.
Foamjection lifts sunken concrete floor slabs back into position without removing or replacing the concrete. Our eco-friendly polyurethane concrete lifting process restores support beneath the slab, improves stability, and creates a safer, level floor that’s ready for normal use immediately—at a fraction of the cost of replacement.
Concrete floors sink when the soil beneath them loses strength. Common causes include:
As support weakens, floors settle unevenly and continue to shift if not addressed.
You may need concrete floor leveling if you notice:
Early repair helps prevent further movement and surface damage.
If nearby concrete has also settled, garage floor leveling, concrete slab leveling, or patio leveling may be needed to stabilize connected slabs and restore consistent height across the area.
Foamjection levels concrete floors 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 floor leveling projects are completed in one visit, and many surfaces are ready for use the same day.
Homeowners choose concrete floor leveling because it fixes uneven surfaces without the cost and disruption of replacement. Lifting restores safety, improves drainage, and keeps existing concrete in place.
For floors that are intact but uneven, leveling is often the most practical solution.



Concrete floors 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 – usually just a few hours.
Concrete floor leveling can help with cracks, but it’s important to understand what it does—and what it doesn’t do.
Leveling lifts and stabilizes the slab by restoring support beneath the concrete. This often prevents cracks from getting worse and can help close minor cracks that formed due to settlement. By eliminating movement under the slab, leveling reduces ongoing stress that leads to cracking.
However, leveling does not remove existing cracks entirely. After the slab is stabilized, cracks can be sealed or repaired as a separate step if needed. For floors that are structurally sound but uneven, leveling is an effective way to stop further cracking and restore a stable surface.
Yes. Floor leveling can help improve drainage when settlement has caused low spots or uneven slopes.
By lifting the concrete back to its proper height, leveling helps restore the intended surface pitch so water or moisture can move away instead of collecting in low areas. This can reduce pooling, moisture buildup, and related issues inside a home, shop, or other building.
The holes are small and patched after lifting. They are much less noticeable than replacement seams.
Yes. The foam is safe for indoor use.
The polyurethane foam is injected below the concrete and cures into a stable, closed-cell material that stays in place. It does not leach into the soil, does not release harmful chemicals, and does not affect indoor air quality once cured.
Because the process happens beneath the slab, it allows concrete floors inside homes, shops, and other buildings to be lifted and stabilized with minimal disruption while providing long-term support.
During foam injection, there may be a very brief, mild scent while the material is injected, but it dissipates quickly as the foam cures. Once cured, the foam is sealed beneath the concrete and is odorless, allowing indoor spaces to return to normal use without lingering smells.
