concrete Slab Stabilization / Lifting

Restore sunken, settling, or rocking concrete slabs to their original grade and strength with our proven slab lifting and stabilization solutions.

Applied Industrial Flooring specializes in concrete slab lifting, levelling, and stabilization using advanced polyurethane grouts. This structural foam is injected beneath the slab to fill voids, re-establish support, and restore the slab’s original elevation. Expanding up to 20 times its original volume, the grout provides rapid, efficient results—curing to 85% strength within 15 minutes and supporting loads over 10,000 lbs per square foot.

Slab settlement often stems from soil erosion, plumbing leaks, poor drainage, underground water migration, or inadequate subgrade compaction. Over time, heavy traffic loads, machinery vibrations, and even the natural concrete curing process can lead to voids and instability beneath the slab. Left unaddressed, this can cause spalling joints, cracking, corner breaks, and potential safety hazards.

Compared to full slab replacement, our method is less invasive, more cost-effective, and completed in a fraction of the time—typically within a few working hours, not 28 days. Our team prepares the area, injects a two-part polyurethane foam and structural grout, and finishes by grinding slab joints if necessary for even elevation.

With over 40 years of experience, we deliver long-lasting results in industrial, commercial, and high-traffic environments, restoring safety and functionality with minimal disruption.
