Transporting fluids in high-pressure pipelines.
Eiffage Génie Civil installs pipelines to transport natural gas, hydrocarbons (raw and refined products and biofuels) and high-pressure fluids (compressed air, ethylene, nitrogen, oxygen, helium and hydrogen). Our teams specialize in complex earth projects, contributing their expertise to small, medium and large-scale sites, from the smallest diameter up to 36 inch-diameters (DN900). They are able to offer high-speed laying techniques over long distances, and also work on structures in operation :
- protection
- pipeline network development and diversion
- inerting and removal
- special points, interconnection
- pipeline fault monitoring
- covering repairs
- work on concentrated structures (compression stations)
- work in confined spaces (pipe repairs and/or replacement in utility tunnels).

Environmentally responsible practices and materials
Sustainable development and the environment are at the heart of the company's choices and actions.
In order to limit the impact of its operations on the environment, Eiffage Génie Civil favours techniques for recycling materials in situ, treating waste and restoring sites.
We are experts in the design and execution of hydraulic testing and regulatory control operations prior to the commissioning of the structure. Our teams have recent, specific equipment that complies with the latest safety and environmental standards.
Respectful of the environment in each of our operations, we make it a point of honour to restore the sites we work on to their original state.
The Pipelines teams in the Jura
Eiffage Génie Civil was chosen by French Jura pipelines company SFPLJ (Société Française de Pipeline du Jura) to replace 11.4 km of pipelines – 4 stretches of DN400 pipeline – in Valdahon (25) in the direction of Switzerland.
Risk management at all stages of the works
Compliance with safety requirements is central to our DNA, driving our teams at all times. In both the study and works phases, they integrate into the works management all the factors guaranteeing safety for project stakeholders, and the integrity of existing facilities. By acting upstream of the project and on early warning signals, our staff work to eliminate risks beyond mere compliance with the standards in force.
