What GEOLIA does
GEOLIA is a privately held French engineering consultancy founded in 2006 and headquartered in Morangis (Île-de-France), specializing in geotechnical studies, environmental assessment of polluted sites and soils, and hydrogeology. The company delivers the full French normative mission stack — G1 through G5 geotechnical missions for construction permits and foundations, A100–A260 environmental diagnostics and management plans, and Water Law / PPRI hydrogeological studies — together with specialized services for historical monuments and an in-house drilling operation of 11 teams supported by an integrated soil laboratory and an 800 m² sample storage facility. Underlying technical assets include a proprietary subsurface database of more than 9,000 drilling projects across the Paris basin and dual OPQIBI and LNE certifications (Domain A since 2018, Domain B since 2023), plus authorization to issue ATTES regulatory certificates under the February 2022 ministerial decree.
The company serves 2,000+ clients and executes approximately 850 sites per year, spanning construction developers, architects and engineering firms, local authorities, industrial site owners, property owners, and historical-monument restoration contractors, primarily in the Greater Paris region with select work in French DOM-TOM. Revenue was €11.5 million in FY2023 and is described by the company as having grown constantly since inception. GEOLIA operates a direct B2B sales model with a five-step engagement process (consultation, quote, on-site drilling, analysis, final report), generates revenue through customized professional-services contracts on a project basis, and reports no paid marketing or external institutional ownership. Leadership is founder-controlled through four Director Generals — Claude MARCIE (President, founder and Court of Appeal expert), Thierry MAZET (Historical Monuments), William BATS and Frédéric ANTOINE (geotechnical engineering) — supported by co-founder Christine LOUREIRO in finance, with 20 geotechnical engineers, a 7-person environment team, and dedicated drilling and support staff.

GEOLIA competitors and assessment
Company assessmentBroad incumbents
- Apave: French technical risk-management company offering inspection, building, and infrastructure consulting including environmental and construction-related assessments. Comparable as a broad French incumbent that competes for technical studies and certifications in the same developer, industrial, and local-authority customer base.
- Setec (Société d'Études Techniques et d'Entreprises de Construction): Major French independent engineering consultancy with infrastructure and environment practices. Comparable as a French engineering consulting peer competing for the same developer, architect, and public-authority clients on technical studies for construction projects.
- Soletanche Bachy (VINCI Construction): Global leader in geotechnical and foundations contracting, part of VINCI. Comparable as a broad incumbent delivering ground engineering and foundation works overlapping with GEOLIA's G2-G5 missions, but at much larger scale and with construction-execution focus rather than just studies.
- Keller Group plc: UK-listed global geotechnical contractor specializing in ground improvement and foundations. Comparable as a broad incumbent overlapping with GEOLIA's geotechnical engineering scope, though primarily a contractor rather than a study-and-investigation consultancy.
- Fugro N.V. Dutch-based global geotechnical, geophysical, and site investigation services company. Comparable as a broad incumbent in subsurface characterization and geotechnical consulting, serving infrastructure and environmental markets with much larger international footprint than GEOLIA.
- Bureau Veritas (Environmental & Infrastructure): Global testing, inspection, and certification firm with significant environmental and infrastructure assessment lines in France. Comparable because it certifies and assesses sites, including brownfield/polluted-site work that overlaps with GEOLIA's LNE-certified environment services.
Direct peers
- Hydrogéotechnique France: French geotechnical engineering firm offering soil studies, drilling, environmental, and hydrogeology services nationwide. Comparable because it directly competes in the same G1-G5 geotechnical mission framework with integrated drilling and laboratory capabilities, just at a broader national geographic scale than GEOLIA.
- Ménard (VINCI Construction): Specialist ground-improvement and geotechnical contractor within VINCI. Comparable as a direct peer in geotechnical engineering execution, overlapping with GEOLIA's G3-G5 supervision missions, though focused on ground improvement execution rather than study-only mandates.
- Antea Group: International engineering and environmental consulting firm with a strong French footprint in water, environment, soil, and site remediation. Comparable because it directly competes in environmental site diagnostics, hydrogeology, and contaminated-land studies - the same regulated service lines where GEOLIA holds LNE and ATTES certifications.
Emerging players
- Burgeap (subsidiary of groupe Ginger): French environmental and water engineering consultancy specialized in soil, water, and pollution studies. Comparable as an emerging specialist competitor with direct overlap in hydrogeology, water-law compliance (Water Law dossiers), and polluted-site diagnostics, the same regulatory niches GEOLIA serves.
