URETEK's patented underground control solutions for airports,pavements, sunken foundations,slabs, bridge jockey slabs, rail, warehouse slabs,infrastrucure etc incorporate precision injection of specially developed highly expansive hydro-insensitive materials enabling very accurate re-grade and slab alignment for ramps, taxiways and runways. The URETEK Deep Injection Process, which is provided with a ten-year material guarantee, drives out water, fills underground soil fissures and voids, and expands to densify the ground. The method avoids the need for excavation and the injected materials can reach 90% strength in around 15 minutes, causing minimum disruption to operations. URETEK's technologies have been used on some 75,000 projects worldwide, including numerous commercial airport and military airfield applications. These include Dallas-Fort Worth, Orlando International, San Francisco International, Los Angeles International, and San Jose airports in the United States; Vienna Airport, Austria; Sydney International and Brisbane International airports, Australia; Toronto-Pearson International Airport, Canada; Paris-CDG Airport, France; Amsterdam Airport Schiphol, Netherlands; Leonardo da Vinci Airport, Italy; Seoul Kimpo International Airport, Korea; Oslo-Gardermoen Airport, Norway; and Basel-Mulhouse, Geneva and Zurich airports, Switzerland and Eindhoven Airport
