What Jarnias does

Groupe Jarnias, founded in 1993 and headquartered in Thyez/L'Haÿ-les-Roses, France, is a privately held specialist in rope access (cordist) work and difficult-access operations, organized as a federation of 20 subsidiaries operating from 28 sites across France, Switzerland, Luxembourg, Tunisia, Morocco, Zambia, Mauritius, Guadeloupe, and Réunion. Its core services span three pillars: (1) JARNIAS Travaux — specialist work-at-height including securing, installation, maintenance, demolition, welding, painting, sandblasting, and non-destructive testing for construction, industrial, energy, civil engineering, and heritage clients; (2) JARNIAS Protection — design, manufacturing, installation and rental of protective nets, tarpaulins, heat-shrink films (ACROSOLS®/THERMO2S), acoustic banners/tents (ACOUSTEAM), lifelines, anchor points, and guardrails; and (3) JARNIAS Formation — certified cordist training (CQP C, CQP TC, OTC) plus a staffing subsidiary (JINT) that supplies qualified cordistes. The group sells exclusively direct to enterprise and public-sector clients (Bouygues, Vinci, Eiffage, EDF, SNCF, RATP, Tour Eiffel, Notre-Dame de Paris, Sénat, PSA, Endemol) under project-based, multi-year contracts with custom quoting; pricing is not publicly disclosed and is highly customized to access complexity and scope. Under PDG Xavier Rodriguez, the group has executed an aggressive roll-up strategy since 2022, integrating ACRO BTP, PROFIL, ALTICITY, ACOUSTEAM, HAUTLINE, THERMO2S, TAN, ALTITAD, SILONET, LUXLINES, and HYDROKARST/SDEM, and in 2025 became the first French BTP group to obtain B Corp certification while holding an AA+ Banque de France credit rating.

Others

• Texyloop: European PVC and technical textile recycling specialist. Partners with Jarnias Protection (announced 2025) for end-of-life recycling of tarpaulins and nets; adjacent ecosystem participant enabling Jarnias' circular-economy and B Corp commitments.
• France Travaux sur Cordes: French trade association for rope access professionals that organizes the Championnat de France des Cordistes, in which Jarnias actively competes. Not a direct competitor but a key industry body shaping standards and certification that Jarnias aligns with.

Broad incumbents

• Haulotte Group: French manufacturer of aerial work platforms (MEWPs) including boom lifts and scissor lifts. Competes indirectly with Jarnias by offering powered access alternatives for high-rise work; headquartered in France and serves similar enterprise clients.
• Tractel Group: International manufacturer of industrial access and lifting equipment, including rope access hardware, lifelines, and fall protection systems. Tractel supplies the kind of safety equipment Jarnias deploys and overlaps in providing installation and inspection services for fall-arrest systems.
• BrandSafway: Global leader in scaffolding, access, and industrial services with broad capabilities in work-at-height. Compared to Jarnias, BrandSafway operates at much larger scale with a focus on scaffolding and conventional access rather than cordist specialization, but competes for similar industrial and infrastructure contracts.
• Multitel Pagliero: Italian-headquartered manufacturer of truck-mounted aerial platforms and access equipment. Provides competing access solutions for high-rise and industrial work; broader equipment portfolio than Jarnias but serves similar industrial and utility customers.
• SGB Group (Altrad-owned): UK-based scaffolding and access services provider, now part of Altrad. Provides alternative access solutions for construction and industrial projects; larger scale than Jarnias and broader geographic footprint, with overlapping customer base in infrastructure and energy.

Emerging players

• Vertical Access LLC: US-based rope access firm specializing in historic preservation, building envelope inspection, and difficult-access consulting. Smaller in scale than Jarnias but provides comparable specialist services for heritage and complex structural work in North America.

Direct peers

• Industrial Access (ROeRS): Belgian rope access company providing industrial services including inspection, maintenance, and NDT across Europe. Similar to Jarnias' HYDROKARST and TAN subsidiaries in offering difficult-access industrial inspection, and competes for the same Benelux industrial clients.
• Sky Aerial Access: UK-based rope access and work-at-height services company providing inspection, maintenance, and installation across industrial sectors. Directly comparable to Jarnias in service offering and target clients (energy, infrastructure, construction), though operating primarily in the UK.
