Settling, cracking, and shifting concrete slabs are often caused by poor soil compaction, soil erosion, or fluctuating moisture levels beneath the foundation. When sub-grade soil sinks or washes away, empty voids form under the concrete, leaving the slab unsupported and causing it to crack, sink, or tilt.
Our Slab Issue Repair Services address both surface-level sinking and deep sub-grade instability. By injecting high-density expansion foam beneath the concrete or installing heavy-duty steel slab piers, we fill empty voids, lift sunken slabs back to their original elevation, and lock the foundation in place for long-term stability.
High-Density Polyurethane Foam: Industrial-grade, hydrophobic expansion foam that cures in minutes, expands up to 15 times its volume, and never washes away in water.
Non-Invasive Installation: Injected through tiny, penny-sized drill holes (⅝”), eliminating the noise, dust, and heavy machinery required for concrete demolition.
Deep Slab Piering: Continuous steel shaft piers installed deep into stable soil strata for heavily loaded concrete slabs requiring heavy-duty structural underpinning.
Rapid Load Return: Polyurethane foam cures within 15 to 30 minutes, allowing foot traffic and heavy vehicles on the slab almost immediately after completion.
Precision Void Filling: Hydrophobic resins expand into the smallest soil gaps beneath the slab, compacting loose base soils and sealing out moisture.
Fraction of the Cost: Slab lifting and void filling cost significantly less than tearing out old concrete, hauling debris, and pouring new slabs.
Zero Down Time: Cures instantly without waiting days for concrete to set, allowing you to use your floors or driveways on the same day.
Addresses the Root Cause: Instead of adding heavy new concrete over weak, shifting soil, our methods stabilize and compact the soil base beneath the slab to prevent future settlement.
