Uneven interior concrete floors create safety risks, affect equipment movement, and disrupt daily operations. Settled slabs inside buildings can lead to cracks, drainage problems, and uneven transitions between spaces.
Interior floor leveling raises sunken concrete slabs without removing or replacing the floor. Foamjection uses polyurethane concrete lifting to restore support beneath the slab while minimizing disruption inside the facility.
Interior floors sink when the soil beneath the slab loses strength. Common causes include:
As support weakens, interior floors settle unevenly and continue to shift.
You may need interior floor leveling if you notice:
Addressing these issues early helps improve safety and maintain smooth operations.
If surrounding concrete has also settled, factory floor leveling, warehouse floor leveling, or loading docks & ramps may also be needed to stabilize connected surfaces and maintain consistent elevation throughout the facility.
Foamjection levels interior 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 interior floor leveling projects are completed efficiently, and many surfaces are ready for use the same day.
Property owners choose interior floor leveling because it corrects uneven slabs without demolition or extended downtime. Lifting restores safe walking and working surfaces while keeping existing concrete in place.
For interior floors that are intact but uneven, leveling is often the most practical solution.



Interior floors become uneven due to soil erosion, poor drainage, soil movement, and settling beneath the slab.
In many cases, yes. Leveling costs less, takes less time, and avoids removing existing concrete.
Most projects are completed in a short time frame, depending on slab size and conditions.
Yes. Polyurethane foam is designed to support equipment, shelving, and daily use.
In many cases, work can be scheduled or phased to limit disruption.
The holes are small and patched after lifting.
Yes. Leveling restores proper slope so water drains correctly.
