What MARTI INFRA AG does

Marti Infra AG is a Swiss specialized environmental remediation and infrastructure services contractor headquartered in Moosseedorf (Canton Bern) and operating as a subsidiary of the family-owned Marti Gruppe, a conglomerate of approximately 80 construction-related companies founded circa 1920. The firm's core offerings span contaminated site remediation (industrial sites, hazardous landfills, lake-bed sediments, shooting ranges), recycling and disposal of contaminated construction materials using jointly developed mobile and stationary soil washing plants (Bodenwaschanlage), rail-mounted tunnel dry cleaning services under the Marti Tunnel Cleaning (MTC) brand, wastewater and groundwater treatment, nuclear power plant modernization and decommissioning services, and dedicated environmental logistics via the Marti Express Shuttle cargo train system with RID/ADR dangerous goods authorization. Notable proprietary or co-developed technologies include modular rail-guided tunnel cleaning systems (deployed at Ceneri Base Tunnel, ~2 x 15 km), underwater sediment suction-box methods (applied at Zürichsee depths of 2–26 m), and large-span air-tight movable remediation halls (up to 150 m span, 18,300 m²).

The firm's commercial model is project-based B2B contracting, with documented contract values ranging from CHF 0.4 million to CHF 200 million. Work is sourced through competitive public tendering with Swiss federal, cantonal, and municipal authorities, alongside direct negotiation with industrial and chemical owners (e.g., bci Betriebs-AG, STEIH SARL, Cimo Compagnie industrielle de Monthey) and rail/energy operators (SBB Infrastruktur, AlpTransit Gotthard AG, AXPO Power AG, Westinghouse). Project delivery occurs through general contractor (Totalunternehmer), consortium (ARGE), and direct contract arrangements, typically leveraging intra-group Marti engineering resources rather than large direct headcount. Operational geographies encompass Switzerland (primary), cross-border remediation projects in France (STEIH Hünigen), and disposal/logistics flows into Germany and the Netherlands.

The company is privately held with no public listing. Specific revenue, headcount (outside the 80-group aggregate), ownership percentages, or management bios are not publicly disclosed. Certifications include ECM (Entity in Charge of Maintenance) and A.C.E.P. (Approved Continuous Examination Programme) for the logistics division, providing regulatory qualifications for restricted public tenders. Key strategic partnerships include joint soil washing technology development with Marti Technik AG and Simatec AG, and a stationary facility co-location with Novakies AG at the Baustoffcenter Lätti site.

Broad incumbents

• SUEZ (Suez Recycling and Recovery): European waste management and remediation major. Direct overlap with Marti Infra on soil treatment, hazardous landfill remediation, and materials recovery, particularly in neighboring France and Germany.
• Implenia AG: Switzerland's largest general construction group with a dedicated infrastructure and environmental engineering division. Overlaps with Marti Infra on large remediation and tunneling contracts but operates as a much broader incumbent.
• Bilfinger SE: German industrial services provider with nuclear decommissioning, environmental remediation, and process-plant capabilities — comparable to Marti Infra's nuclear and industrial-site service lines.
• Veolia Environnement: Global hazardous waste management and industrial services incumbent. Comparable on soil washing, contaminated-site remediation, and special-waste disposal at much larger international scale.
• Holcim (Schweiz) AG: Operates cement kilns that provide thermal recovery for contaminated materials — a downstream disposal channel Marti Infra uses. Also active in aggregates/recycling markets that overlap with Marti Recycling Center activities.
• AF-Consult Switzerland / AFRY: Engineering consultancy active in tunnel, rail, and environmental infrastructure. Comparable on railway tunnel design and operations-support services adjacent to Marti Tunnel Cleaning work.

Others

• SBB Cargo AG: Swiss freight rail operator. Marti Infra's Marti Express Shuttle operates on the SBB network using SBB locomotives — adjacent logistics ecosystem relationship rather than a competitor.

Direct peers

• Studsvik AB: Nordic nuclear and environmental services specialist. Overlaps with Marti Infra's KKW Beznau work on reactor services, decommissioning, and radioactive/industrial waste handling.
• Walo Bertschinger AG: Swiss civil engineering and environmental contractor with strong presence in remediation and railway infrastructure. Direct competitor for cantonal tenders and tunnel-related contracts.
• Egli AG: Swiss environmental remediation and demolition contractor with comparable portfolio of Altlasten remediation projects. Competes with Marti Infra on cantonal and municipal tenders in Switzerland.
