Curled Slab Repair

Serving the New England Region with rapid, cost-effective solutions for settling and uneven concrete

Curled Slab Repair with Polyurethane Injection Technology

Concrete curling can cause major serviceability issues in warehouses, factories, and commercial buildings. Over time, edges of concrete slabs lift due to uneven drying, temperature differences, or subbase problems — leading to unsafe transitions, joint damage, and potential tripping hazards.

At Engineered Foundation Technologies (EFT), we specialize in polyurethane injection for curled slab repair across Massachusetts and New Hampshire. Our process stabilizes subfloor voids, restores surface flatness, and minimizes downtime for operating facilities.

Precision MattersOnce the void space is filled with high-performance polyurethane, EFT technicians fine-tune the surface profile. Any remaining unevenness is corrected with high-strength mortar, ensuring a level, durable floor that meets industrial performance standards.

Common Problems Caused by Curled Concrete Slabs

Uneven and Raised Slab Edges

Differential drying or curing conditions can cause the edges of a concrete slab to lift upward. This unevenness creates hazardous transitions and can lead to damage at control joints or slab intersections.

Joint Spalling and Cracking

Unsupported slab edges often result in cracked or broken joints under forklift or vehicle traffic. Over time, this deterioration worsens, creating unsafe and costly maintenance conditions.

Disrupted Operations and Equipment Wear

Uneven floors can impact warehouse traffic, damage equipment wheels, and slow down daily operations — particularly in facilities using precision material-handling systems.

Advantages of EFT’s Polyurethane Curled Slab Repair

Minimally Invasive Process

Polyurethane foam injection requires only small access points and can be performed without removing machinery or shutting down your facility.

Precision-Leveling Technology

EFT uses fast-reacting polyurethane designed for controlled expansion. This allows for exact lifting and stabilization of the curled slab edges, restoring smooth, level transitions.

Rapid Return to Service

Most projects are completed in hours, not days. Once injected, the material cures quickly — floors can often be returned to use within minutes.

Durable, Long-Term Solution

The cured foam forms a dense, stable base that prevents future settlement or curling, ensuring long-lasting performance and cost savings over slab replacement.
