Trevi Group

What Trevi Group does

Trevi Group is an Italy-based, publicly listed underground engineering group founded in 1957 in Cesena by Davide Trevisani, operating across two core divisions: the Trevi Division, which executes specialized foundation works, soil consolidation, and pollution remediation for large infrastructure projects (metros, dams, ports, bridges, railways, highways, industrial and civil buildings); and Soilmec, which designs, manufactures and markets machinery and systems for underground engineering, with over 50 years of manufacturing experience and more than 5,000 large-diameter pile machines produced. The group's proprietary technology portfolio includes E-JET elliptical jet grouting, Hydromill diaphragm wall systems, deep drilling capable of 250+ meters, and impermeable screen systems for dam construction, all refined through vertical integration between equipment design and on-site execution.

The group serves governments and large engineering clients on mission-critical infrastructure globally, with documented reference projects including Metro C Rome, the Iraqi Government Mosul Dam rehabilitation, NEOM 'The Line' in Saudi Arabia, Grand Paris Express, Stockholm Norvik Port, Cebu-Cordova Link Expressway and Four Frankfurt. Distribution and execution are supported by a wholly-owned subsidiary and dealer network spanning roughly 30+ countries across five continents (Europe, North America, South America, Asia Pacific, Middle East and Africa), with named entities in Italy, France, Germany, UK, USA, Brazil, Colombia, UAE, Saudi Arabia, India, Japan, Philippines, Nigeria, Egypt and others. The parent, TREVI – Finanziaria Industriale SpA, has been listed on the Milan Stock Exchange since July 1999 and is controlled by CDP Equity Investimenti S.p.A. and Polaris Capital Management LLC.

Revenue is generated through two streams — specialized foundation and soil consolidation services (professional services, quote-based pricing on large projects) and machinery and equipment manufacturing/sales via Soilmec. Reported revenue is approximately €715 million (FY2024 referenced) on a workforce of 5,001–10,000. Beyond core services, the group operates the Trevi Group Academy (management training) and the Foundations Technology Academy (technical field training, established 2006) as a deliberate talent infrastructure. After divesting its oil & gas division to India's Meil for ~€116M in March 2020, the group has refocused on its higher-margin underground engineering core, and has accumulated ESG credentials (EcoVadis Silver Medal 2025, FT Europe's Climate Leaders 2025, SA8000, ISO 30415:2021, UNI/PdR 125:2022) to remain competitive in ESG-gated infrastructure tenders.

Direct peers

• Casagrande Group: Italian manufacturer of foundation equipment and specialty piling rigs; competes with Soilmec in the equipment-manufacturing segment and with Trevi in execution.
• Bauer AG: German-based specialist foundation contractor and manufacturer of foundation equipment; competes directly with Trevi and Soilmec across piling, ground improvement, and foundation works globally.
• Keller Group plc: UK-based geotechnical solutions contractor with similar offerings in ground engineering, piling, and soil improvement; directly comparable in specialization, customer base, and project delivery model.
• Soletanche Bachy (Vinci Construction): World leader in deep foundations and ground improvement, part of Vinci; competes head-to-head with Trevi on large underground engineering projects including metros, dams, and ports.
• Hayward Baker (Keller US): US arm of Keller Group providing geotechnical construction services including deep foundations, ground improvement, and environmental remediation.

Others

• Trevi Group subsidiaries list (already in company data): Trevi's own regional subsidiaries (e.g., Trevi Spezialtiefbau, Trevi Foundations Philippines, TREVIICOS) are documented internal entities rather than external peers.
• Liebherr: Manufacturer of heavy construction equipment including foundation and piling rigs; technology and equipment comparable to Soilmec's product lines.

Broad incumbents

• Vinci Construction: Major global construction and concessions group whose Soletanche Bachy subsidiary competes with Trevi in specialty foundations; broader portfolio provides scale and adjacent capabilities.
• Strabag SE: Large European-headquartered construction group with significant tunneling and ground engineering activities; overlaps with Trevi on major civil infrastructure projects.
• Webuild (Salini Impregilo): Italian-origin global infrastructure contractor active in dams, metros, and tunnels; competes for many of the same megaprojects Trevi is involved in.
