Geoquest USA delivers engineered solutions for heavy civil infrastructure and site development projects across the nation. We combine engineering expertise, manufacturing excellence, and hands-on project support to help contractors, engineers, and owners move projects from concept to construction with confidence.

In 2025, The Reinforced Earth Company USA became Geoquest USA, aligning with our global Geoquest organization (formerly Terre Armée). While our name has evolved, our commitment remains the same: providing innovative, reliable solutions backed by decades of technical leadership and worldwide experience.

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 have helped advance mechanically stabilized earth (MSE) technology while expanding our portfolio to address today’s infrastructure challenges.

Today, Geoquest USA offers a comprehensive range of solutions, including retaining wall and arch systems, geosynthetics, and precast concrete products that are engineered for a variety of geotechnical applications. Geoquest USA offers solutions for every stage of infrastructure construction, from ground stabilization and soil reinforcement to the finished site elements that bring a structure to completion.

Tens of thousands of Geoquest structures and systems are in service across all 50 states, supporting highways, bridges, railways, ports, industrial facilities, mining operations, and other critical infrastructure. From localized improvements to large-scale design-build programs spanning millions of square feet, we bring the scale, experience, and technical depth needed to deliver lasting results.
