What Soletanche Freyssinet does
Soletanche Freyssinet is a French specialty construction and engineering group operating as a wholly-owned subsidiary of VINCI Construction, with headquarters in Rueil-Malmaison, France, and 10,000+ employees. The group is organized into six subsidiary brands — Soletanche Bachy (soil engineering and foundations), Menard (ground improvement), Geoquest (reinforced earth and retaining structures), Freyssinet (structural engineering, post-tensioning, cable-stayed systems), Nuvia (nuclear services), and Sixense (digital monitoring) — delivering four core business activities: Soils, Structures, Nuclear, and Digital. Technical capabilities rest on proprietary methods such as Reinforced Earth® walls (Terre Armée), underground cut-off walls for dam integrity, underwater nuclear diving operations for decontamination and dismantling, cable-stayed roof systems for large stadiums, and digital sensor-based monitoring for infrastructure.
The company's go-to-market is enterprise field sales and project-based engagement with government and large infrastructure clients, including agencies such as the U.S. Army Corps of Engineers, the City of Paris, and nuclear power operators across at least 17 countries. Revenue is generated through custom-quoted specialty construction contracts, long-term maintenance engagements, and engineering services, with no public pricing disclosure. The group maintains a global footprint across Europe, North America, South Asia, Southeast Asia, and Eastern Europe, and continues to extend capabilities through targeted acquisitions (Marsein in 2025; Carpi and ConeTec in 2017) and the build-out of its Sixense digital vertical.
