Slabjack Geotechnical, a family-owned concrete repair company with locations in Spokane, Tri-Cities, Wenatchee, and Puget Sound, is providing specialized airport runway concrete repair services across Washington and Northern Idaho. The company's approach addresses the unique demands of aviation facilities, where concrete must withstand enormous aircraft loads, constant traffic cycles, and harsh environmental exposure.
Airport concrete, including runways, taxiways, and aprons, is subject to stresses far exceeding those in roadways or parking structures. Commercial jets, cargo aircraft, and military vehicles apply concentrated loads, while continuous vibration, braking forces, turning movements, moisture intrusion, freeze-thaw cycles, fuel exposure, and temperature fluctuations accelerate deterioration. Standard concrete repair methods are insufficient for these conditions, requiring specialized techniques.
Slabjack Geotechnical utilizes engineered polymer injection systems designed to restore and enhance load-bearing capacity. The process involves injecting a guaranteed on-ratio polymer that cures into an extremely hard, durable grout, filling voids, stabilizing subgrade soils, correcting differential settlement, and reinforcing slabs. This ensures consistent structural strength to maintain FAA- and DOT-compliant surface performance.
Maintaining durability under constant aircraft and ground traffic is critical for long-term pavement performance. Taxiing aircraft, refueling trucks, baggage equipment, and ground support vehicles create repetitive loading and vibration that can cause unsupported slabs to rock, crack, or separate. Slabjack Geotechnical's stabilization and lifting systems provide uniform support beneath airport concrete, eliminating voids and preventing slab movement. This reduces joint deterioration, minimizes fatigue damage, and helps prevent foreign object debris (FOD) risks that could compromise aircraft safety.
Compared to full slab replacement, Slabjack Geotechnical's method extends the life of airfield surfaces while preserving structural continuity across large paved areas. Airports throughout Washington and Northern Idaho trust the company to deliver structurally sound, compliant, and long-lasting repair solutions. Founded in 2011 by Jerald and Ann Sargent, Slabjack Geotechnical offers a full range of concrete services, including slabjacking, pressure grouting, concrete crack and joint sealing, and sealing of leaking culverts, large-diameter pipes, and concrete ditches.
