Rocky Flats is a Department of Energy Superfund cleanup site. Beginning in 1952, Rocky Flats made components for nuclear weapons using various radioactive and hazardous materials including plutonium, uranium and beryllium. Nearly forty years of nuclear weapons production left behind a legacy of contaminated facilities, soils and ground water.

The removal of contaminated soil from a Rocky Flats landfill has created a potentially unstable slope measuring 650 lineal feet. Ensuring slope stability is essential at the landfill site to prevent contaminated soils from compromising an adjacent creek.

To stabilize the slope, engineers designed a 20’ tall reinforced soil buttress, comprised of structural soils, aggregates and high-strength biaxial geogrids. The contractors choose Synteen SF 12 for its affordability, flexibility and high tensile strength.

The site, scheduled to be completed in 2006, will be turned into a National Wildlife Refuge managed by the US Fish and Wildlife Service.
