A marble and granite warehouse in Tampa, FL was facing serious slab settlement issues that threatened operational safety and efficiency. Geotechnical testing revealed weak subgrade soils unable to support the immense weight of heavy stone inventory and machinery. The result—uneven floors, visible depressions, and growing safety hazards.

The warehouse owner needed a permanent stabilization solution that could:

• Restore slab stability
• Avoid the cost and downtime of full slab removal
• Minimize disruption to daily operations

A traditional tear-out and replacement was estimated to take a full week and cost nearly five times more than alternative stabilization methods. For a high-traffic commercial facility, that kind of downtime was not reasonable.

Repairing a commercial warehouse floor comes with unique technical challenges:

• Thicker and denser slabs compared to residential concrete
• Heavy, concentrated loads from forklifts, storage racks, and inventory
• Limited ability to shut down operations during repair

Achieving lift and stabilization in these conditions required strategic planning, precision execution, and real-time monitoring. Helicon’s team needed to navigate structural complexities without interrupting warehouse workflow—a challenge requiring both technical expertise and operational awareness.

Step 1 – Strategic Repair Plan

After a thorough site assessment, Helicon proposed a two-part polyurethane injection approach. This method would allow for deep soil stabilization and precise slab lifting without full demolition.

Step 2 – Polyurethane Injection

• Material used: 247 pounds of two-part polyurethane grout
• Process: Small injection points drilled into the slab allowed grout to flow beneath the concrete
• Results: Foam expanded instantly, filling voids, compacting weak soils, and lifting the slab back into position

This non-invasive approach meant there was no need to move heavy equipment or inventory off-site, saving valuable time and money.

Step 3 – Rapid Turnaround

Thanks to precise material placement and continuous monitoring, the entire repair was completed in under one day—far faster than traditional concrete replacement.

The Results

By the end of the project, the warehouse floor was:

• Level, stable, and safe for heavy traffic
• Reinforced against future settlement
• Restored without any operational downtime

The owner avoided costly slab replacement, kept business running, and gained a long-term foundation solution. 

Why Polyurethane Injection is Ideal for Commercial Floors

For warehouses, factories, and distribution centers, polyurethane injection offers key advantages over traditional replacement:

• Speed: Projects often completed in hours, not days or weeks
• Minimal disruption: No large-scale demolition or heavy equipment removal
• Durability: Strong, water-resistant material that holds up under heavy loads
• Cost savings: Lower labor and material costs compared to tear-out and replacement
