We provide retaining walls and geotechnical structures for heavy civil infrastructure projects across the country. We bring together engineering, manufacturing, and hands-on project management to support contractors, DOTs, and owners from concept through construction.

In 2025, The Reinforced Earth Company USA became Geoquest USA, aligning with our global Geoquest group (formerly Terre Armée). The evolution of our name reflects the breadth of our geotechnical solutions and worldwide strength behind every project we support.

Our U.S. story began in 1971 with a landmark landslide repair in California’s Angeles National Forest, completed in partnership with Caltrans using the newly patented Reinforced Earth® system. Since then, we’ve helped shape the advancement of MSE technology while expanding our portfolio to meet the demands of modern infrastructure.

Today, tens of thousands of our structures stand in every state – supporting highways, bridges, railways, ports, mining operations, and more. From small structures to multi-million square-foot design-build projects, we bring the experience, scale, and technical depth to get it done right.
