What Groupe Géotec does
Groupe Géotec is a privately held French geotechnical and environmental engineering firm headquartered in Quetigny (Dijon) and founded in 1973 by François Barnoud, now led by his son Olivier Barnoud. The company delivers end-to-end geotechnical and environmental services — preliminary soil studies (G1) through design (G2), execution (G3-G4) and diagnostic (G5) missions — alongside specialized offerings in maritime, soil rehabilitation, structural diagnostics, natural-risk engineering, geothermal, geophysics, deep exploration drilling, and road geotechnics. Its technical platform is anchored by 15 in-house laboratories, ~150 field investigation teams, and proprietary drilling equipment it designs and manufactures itself (including the TB350 short-mast rig and PSM16 deep-drilling workshop capable of coring up to 1,200 m).
The firm executes more than 24,000 projects per year and serves enterprise and public-sector clients across construction, civil infrastructure, energy (nuclear, renewables, grids), and environmental segments. Marquee references include SNCF Réseau (LNPCA Provence-Côte d'Azur rail project), RTE (offshore wind and underground transmission lines), Bouygues (EPR2 Penly nuclear), TELT (Lyon-Turin tunnel), and the Ariane 6 launch pad in French Guiana.
Groupe Géotec operates through 24 mainland France agencies and 19 subsidiaries spanning 8 countries — France, Belgium, Italy, Spain, Monaco, Senegal, Guinea, Côte d'Ivoire — plus overseas-territory entities in New Caledonia, French Polynesia, Reunion, Mayotte, and French Guiana. Revenue is generated through project-based professional-services contracts awarded via public tenders and direct enterprise engagement, with custom pricing and multi-year contract cadence. The company is family-controlled, with over 50% of employees participating as shareholders through FCPE employee investment funds holding approximately 3% of capital. Reported revenue is €132M (French site) / €120M (English site) with 1,020 collaborators worldwide.

Groupe Géotec product offering
Product offeringCore offering
Groupe Géotec is a geotechnical and environmental engineering consultancy that delivers soil studies, subsurface investigations, drilling, in-situ testing, laboratory analysis, and engineering recommendations for construction and infrastructure projects. Its services span the full project lifecycle (G1 preliminary studies through G5 diagnostics) and include adjacent specializations in maritime works, soil rehabilitation, natural hazards, geothermal, geophysics, exploration drilling, and road engineering. The group also designs and manufactures its own drilling rigs and survey equipment.
Product overview
Groupe Géotec is a unified geotechnical and environmental engineering group, not a modular software platform. Its core offering is a comprehensive suite of in-house geotechnical and environmental engineering services spanning the full project lifecycle — from preliminary soil studies (G1) through design (G2), execution (G3–G4), and diagnostic (G5) phases. This core is delivered alongside 15 geotechnical laboratories and approximately 150 field investigation teams operating proprietary equipment including the TB350 short-mast drill rig and the PSM16 deep-drilling workshop (up to 1,200 m). The group has expanded from its historical geotechnical foundation into adjacent specializations including Maritime, Environnement, Diagnostic Structure, Risques Naturels, Géothermie, Géophysique, Exploration, and Route engineering, all supported by its in-house equipment manufacturing capability. Groupe Géotec operates through a network of 24 French agencies and 19 subsidiaries across 8 countries (France, Belgium, Spain, Italy, Senegal, Guinea, Côte d'Ivoire, Monaco), including named sub-brands and acquired entities such as Arches Études, A2EP-Géotec, C.S.I (Italy), Group Verbeke (Belgium), Géotec Afrique, Géotec Energie, Envisol, and others that extend its geographic reach and technical scope.

Groupe Géotec competitors and assessment
Company assessmentBroad incumbents
- Egis: French engineering group operating in transport, urban, energy and environment. Comparable on infrastructure and energy-sector engineering mandates; broader and less specialized than Géotec in geotechnics.
- Arcadis: Dutch global design and engineering consultancy with significant geotechnical and environmental practices. Comparable client base (large public infrastructure, energy) but operates at much broader scale across multiple engineering disciplines.
- Fugro: Dutch global leader in geotechnical, geoscience and offshore site investigation. Overlaps Géotec on geophysical, geotechnical and offshore-wind foundation investigations, but with a much larger international footprint and offshore focus.
- Keller Group: UK-listed global geotechnical contractor providing ground engineering and foundations. Comparable to Géotec on heavy civil and infrastructure projects, with broader international scale.
Direct peers
- Antea Group: European environmental and geotechnical engineering consultancy active in France and the Netherlands. Comparable on contaminated-site, hydrogeology and environmental-services capabilities overlapping Géotec's Environnement and Revalorisation des sols lines.
- Terrasol (setec group): French geotechnical engineering consultancy within the setec group, specializing in soil mechanics, foundations, and slope stability. Closely mirrors Géotec's consulting-led geotechnical offering in France.
- Menard: Bureau Veritas-owned geotechnical specialist with global reach, offering soil improvement, ground engineering and in-situ testing. Closely overlaps Géotec's drilling, in-situ testing and ground-improvement service lines.
- Soletanche Bachy: VINCI Construction subsidiary and the leading French geotechnical and foundations contractor. Directly comparable to Géotec on ground engineering, deep foundations, and tunnelling geotechnics across France and internationally.
Others
- Bouygues Travaux Publics: Major French civil contractor and a key client of Géotec (e.g., EPR2 Penly partnership). Adjacent ecosystem participant: both customer and indirect competitor for embedded geotechnical work on large French infrastructure.
Regional players
- NGE Fondations: Foundations and geotechnical arm of French construction group NGE, primarily serving the French market. Comparable on ground engineering and foundation services for French infrastructure, with a stronger contractor bias.
