Level Uneven Interior Floors

Interior slab settlement causes operational issues in commercial and industrial buildings. Unlevel floors can lead to equipment misalignment, shelving instability, and trip hazards for staff. Polyurethane injection levels sunken concrete slabs from beneath, without excavation or shutdown. The process provides fast, durable results with minimal disruption to your facility.

What Is Interior Floor Leveling?

Interior floor leveling is a method of lifting and stabilizing settled concrete slabs inside commercial buildings. The process uses expanding polyurethane to fill voids beneath the slab and gently raise it back to its designed elevation.

This solution is ideal for tilt-up warehouses, retail centers, manufacturing floors, and other large buildings where maintaining level surfaces is critical for safe, efficient operation.

Where Might This Be Needed?

Warehouses with forklift traffic
Commercial retail spaces
Tilt-up distribution centers
Data centers with floor-mounted systems
Manufacturing lines
Interior corridors and back-of-house areas

Is Interior Floor Leveling Necessary?

Yes. Uneven interior slabs pose safety risks and operational inefficiencies. Unstable floors can affect sensitive equipment, loading operations, and inventory racking.

Leveling interior floors with polyurethane injection restores both performance and safety. It avoids costly floor replacement and minimizes business disruption, making it essential for time-sensitive facilities.

What Are the Advantages of Interior Floor Leveling?

Restore smooth, safe working surfaces.

Minimal Disruption: Work is completed without moving racking or equipment.

Increased Equipment Life: Prevents vibration-related damage from uneven surfaces.

Safety Compliance: Reduces slips, trips, and floor instability.

Fast Cure Time: Areas return to service within hours.

Long-Term Durability: Material resists future movement and washout.

Common Problem Areas

Aisleways between racks
Loading zones near interior docks
Walkways through production areas

Floor transitions between construction phases
Slabs over poor fill material
