Reliable Slab Settlement Repair for Every Project

Slab settlement — caused by soil movement, erosion, or poor compaction — leads to uneven concrete, safety hazards, and structural stress. Engineered Foundation Technologies (EFT) specializes in repairing settled slabs using cutting-edge polyurethane foam injection and complementary geotechnical techniques that outperform traditional grouts.

From residential walkways and patios to large commercial warehouse floors, our solutions restore surface level, improve load-bearing conditions, and extend the lifespan of existing concrete without costly tear-out and replacement.

High-Tech Solutions, Minimal Impact

Polyurethane foam technology is lightweight, high-strength, and fast-curing — allowing repairs to be completed quickly and with minimal disruption to daily use and business operations.

Common Causes of Slab Settlement

Poor Subsoil Conditions

Weak, unconsolidated, or improperly compacted soils can compress or erode over time, leading to differential settlement beneath concrete slabs.

Water Infiltration and Erosion

Water from grading issues, drainage failures, or flooding can wash away soil fines, creating voids that undermine slab support.

Uneven Load Distribution

Heavy machinery, storage loads, and traffic patterns can exacerbate slab settlement where underlying soils lack sufficient strength or density.

Advantages of EFT’s Slab Settlement Repair Methods

Superior Material Performance

Polyurethane foam offers greater strength, lighter weight, and better expansion control compared to traditional mudjacking grouts.

Precision Concrete Raising

Our slabjacking process economically lifts settled concrete with accurate control, restoring proper slope and surface flatness.

Soil Stabilization Integration

When settlement is caused by poor soils, we incorporate soil improvement techniques (e.g., permeation or compaction grouting) to strengthen subgrades.

Versatile Applications

From residential slabs to warehouse floors and public walkways, our repair methods adapt to projects of all sizes and traffic demands.

Slab settlement is the sinking or shifting of a concrete slab due to unstable soil underneath, commonly caused by soil shrinkage from dryness (leaks, drought), washout (plumbing leaks), or poor compaction during construction
