Geoquest

What Geoquest does

Geoquest, formerly Terre Armée and rebranded in 2025, is a French-headquartered geotechnical engineering company specializing in soil-structure interaction and mechanically stabilized earth (MSE) solutions. Operating as a subsidiary of Soletanche Freyssinet, the firm originated the Reinforced Earth concept in 1964 and has since delivered more than 100,000 projects globally. Its technology portfolio spans MSE retaining walls (Reinforced Earth, TerraMet, TechWall, T-Wall, GeoTrel, TerraTrel, Piano Wall), precast arches and boxes (TechSpan, TechBox), reinforced slopes (ArmaStone, ArmaGreen), geosynthetics (ArmaLynk, ArmaGrid, TerraFlow, TerraLine GCL, TerraTextile, TerraDyke, TerraGreen, ArmaWeb), and geohazard protection systems (TerraNail, rockfall nets), supported by patented components such as TechSpan's funicular-curve geometry and ArmaLynk's high-tenacity PET geogrid.

Geoquest serves engineering firms, contractors, government agencies, and infrastructure developers across six end-markets: transport infrastructure (roads, motorways, railways, airports), hydraulic infrastructure (ports, coastal works, rivers, waterways), resources and industry (oil and gas, mining, energy, industrial platforms), urban development, waste management, and military/defense. Revenue is generated through project-based contracts combining custom engineering design services with the supply of proprietary MSE components and geosynthetic materials, with project lifecycles typically spanning multiple years and pricing determined per project specification.

The company operates a global enterprise field-sales model via nearly 40 subsidiaries and local agents across more than 40 countries, providing localized technical consultation, design support, and material supply. In 2026 it launched Geoquest Design, an online preliminary design platform for TechSpan structures, and acquired Grupo TDM's geosynthetics division to expand its geosynthetics manufacturing footprint.
