What solprojet does

Solprojet is a French private geotechnical and environmental engineering consultancy headquartered in Verrières-le-Buisson, founded in 2009 by Kamran Maleki. The firm delivers integrated services across five pillars: Géotechnique (G1–G5 missions per French geotechnical standards), Diagnostics (structural disorder expertise), Hydrogéologie (groundwater studies, pumping tests, water-law dossiers), Sites et sols pollués (contaminated-site diagnostics under NF X 31-620, including Plan de Gestion and EQRS), and Sondages (drilling, piezometer installation, penetrometer testing, in-house soil mechanics laboratory). Its work spans preliminary site studies, project-level design, execution supervision, and remediation management, anchored by an in-house drilling fleet capable of accessing difficult urban and peri-urban sites.

The business model is professional-services fee-for-project work sold directly to project owners (maitres d'ouvrage), design firms (maitres d'œuvre), real estate developers, construction companies, municipalities, and individuals in the Ile-de-France region. Distribution is direct B2B sales driven by relationships, certifications (notably OPQIBI), and a track record of 5,000+ completed studies and 1,500+ clients. The firm is founder-owned and bootstrapped, with no external investors, parent entities, or disclosed funding rounds. There is no evidence of digital, software, or AI-based productization; revenue is tied to billable engineering hours and field investigations.

Functional benefit

Products and services

• Geotechnical Studies (Géotechnique) Geotechnical engineering studies covering soil mechanics and subsurface characterization to support construction, infrastructure, and development projects. Used by project owners, design firms, and developers to assess ground conditions prior to or during a build.
• Structural Diagnostics (Diagnostics) Diagnostic assessment of structural disorders in existing buildings and structures, supporting owners and consultancies in identifying causes of defects and informing remediation decisions.
• Hydrogeology (Hydrogéologie) Hydrogeological studies and groundwater analysis to characterize subsurface water conditions for construction, environmental, and water-resource projects.
• Contaminated Sites (Sites et Sols Pollués) Assessment and management of polluted or potentially polluted sites, supporting regulatory compliance, redevelopment decisions, and environmental risk evaluation for landowners and developers.
• Soil Drilling and Investigations (Sondages) On-site soil drilling, sampling, and in-situ investigations (sondages) performed by Solprojet's field crews to support geotechnical, hydrogeological, and contaminated-site studies.

Direct peers

• Ginger CEBTP: Leading French geotechnical and materials testing group offering the full G1–G5 mission stack, soil investigations, and environmental diagnostics nationwide. Direct competitor to Solprojet in urban and peri-urban geotechnics, with materially larger scale and lab footprint.
• Geotec (Groupe Géotec): French specialist geotechnical engineering firm providing studies, in-situ testing, and laboratory analysis across France. Closely comparable to Solprojet's offering and target market, with broader geographic reach.
• Antea Group: International engineering and environmental consulting firm with strong French operations in soil, groundwater, and contaminated-site investigations. Directly comparable on hydrogeology, environmental diagnostics (NF X 31-620), and decontamination supervision.
• Burgeap (Egis group): French environmental and geotechnical engineering consultancy specializing in soil and groundwater investigations, contaminated-site diagnostics, and dewatering/hydrogeology studies. Highly comparable to Solprojet's environmental diagnostics and hydrogeology streams.

Broad incumbents

• Fugro: Global geotechnical, geoscience, and site characterization company with extensive French operations covering geotechnical investigations, environmental site assessment, and offshore/onshore surveys. Operates in the same domain as Solprojet but at much larger scale and with broader service lines.
• Apave: Major French risk management and technical consultancy group offering building diagnostics, environmental services, and technical inspections. Overlaps with Solprojet in structural-disorder diagnostics and environmental site assessment as part of a much wider portfolio.
• Bureau Veritas: Global testing, inspection, and certification firm with a significant French construction and environmental services practice. Comparable on contaminated-site diagnostics, building condition assessment, and project compliance services, though not specialized in geotechnical missions.
• WSP in France: Global engineering consultancy with French geotechnical, environmental, and building-restoration practices. Comparable to Solprojet on geotechnical studies and structural disorder diagnostics, with much larger multidisciplinary capacity.
• Arcadis: Global design and engineering consultancy with French operations spanning geotechnical engineering, environmental remediation, and urban development. Overlaps with Solprojet's integrated offering as part of a much wider portfolio.
• Setec: Major French multi-disciplinary engineering group covering geotechnics, structures, environment, and project management through subsidiaries (e.g., setec géotechnique, setec environnement). Direct overlap on geotechnical missions and environmental diagnostics, with broader service lines.
