Infrastructure branch Making all the difference

A major player in France and abroad

Eiffage Génie Civil's Nuclear and Industrial Division has considerable experience in thermal and nuclear power stations and also in the chemical and petrochemical sectors.

This undisputed nuclear specialist  originated in the 1920s with EGI (Entreprise Générale Industrielle), French market leader in design and build high-rise structures such as chimneys, air coolers and silos. The division has since been involved in constructing a large number of air coolers in French nuclear power stations.

The division now contributes its expertise to the new construction, maintenance and dismantling of high-rise structures, conventional industrial infrastructure (thermal power stations, cement works, agribusiness infrastructure, oil services etc.) and nuclear structures (power stations, fuel cycles, research and test facilities).


    Our specific professional certifications guarantee safe, fast operating procedures.


    Our experience dates back to the first half of the 20th century.


    We have major engineering resources at our disposal.

Groundbreaking solutions

The Nuclear and Industrial Division offers appropriate solutions for major industrial and energy projects, including in situ tests (destructive or otherwise) repairs, structural reinforcement against earthquake risk and environmental audits. With our constant technology monitoring, we can adapt our methods to obtain the best possible diagnostic.

QHSE certification and nuclear qualifications

Eiffage Génie Civil's Nuclear and Industrial Division upholds the highest QHSE standards in order to protect our workforce and the environment, and ensure optimum customer satisfaction. Our capabilities in the field  of social and environmental responsibility are certified as follows:

  • Occupational risks prevention management : OHSAS 18001
  • Prevention of exposure to ionizing radiation : CEFRI
  • Quality management : ISO 9001
  • Environmental management  : ISO 14001

We also hold the EDF UTO (Operational Technical Unit) standard, certifying our ability to comply with the requirements of a nuclear environment. Eiffage Génie Civil's Nuclear and Industrial Division has a proactive staff training and risk awareness approach. We implement groundbreaking safety solutions including non-slip mats, anti-vibration robotics technology, magnetic cutting and sampling tools with low noise and vibration levels and an ultra-light modular formwork system.

Tall structures and maintenance

Our project teams carry out new building work, silo maintenance and chimney and air cooler construction on a daily basis, in electrical power plants and industrial environments.  Our in-house experts have developed access and lifting solutions such as aerial platforms, manlifts, winches and elevators for very tall buildings and engineering structures.

The division has its own resources and qualified staff for the diagnosis and assessment of existing structures, recommendations and studies for effective repairs solutions, and where special problems exist - corrosion, cracks, carbonation, internal sulphate reaction (ISR) - reinforcement with carbon, BSI®, additional prestressed concrete etc.  We are also able to supervise work in remote areas with our personnel trained in rope access.

Working in radioactive areas

The division is a recognized expert in radioactive environments. Our permanent team in operation at Cattenom nuclear power station has extensive experience in specialist works including opening hoppers, coring, sampling and sawing, and operations in an ionizing environment. Other teams are involved in ongoing projects in north-east France and in all our nuclear power stations as part of specific multi-site operations. Our technical recommendations confirm that we have integrated the ALARA concept (principles for reducing radiation exposure).

Engineering and environment

As an experienced builder, we contribute our extensive know-how to clients wishing to demolish their facilities in compliance with environmental and safety standards. Our technical skills and in-depth structural knowledge enable us to offer the safest, fastest and most suitable operational procedure for each project. With the support of an integrated design and engineering department boasting powerful calculation resources and leading- edge design tools, the Nuclear and Industrial Division is able to position at the forefront of the market.


  • Texsol® : in addition to its other activities, the Nuclear and Industrial Division is the exclusive owner of the Texsol® patent. This product was developed by the IFSTAR (LCPC), in 1980 and is a natural construction material, a composite mix of sand and synthetic fibres. Its intrinsic qualities make it ideal for the protection of retaining walls and the containment of industrial structures.  It also has excellent fire and noise protection properties and deformation capacities. Texsol®can be seeded (green wall) or covered. It is flexible, quick and economic to install, and can be put into use all over France and Europe.
  • Dry core drilling: our teams have developed a highly secure graphite reactor sampling process. The dry core drilling operations must be carried out in a controlled environment, at moderate temperatures and limiting dust generation, to avoid altering the properties of the raw material. This process is highly effective and leaves no doubt as to the origin of radioactive traces in the samples collected.
  • Douce Hydro dampers : the Nuclear and Industrial Division developed the calculation method used in  Douce Hydro viscous fluid dampers for protection from shock and energy dissipation in the seismic and civil engineering industries. The process is particularly appropriate on sensitive sites where exposure is a major preoccupation.
  • Flat carbon : the division strengthens reinforced concrete structures with the addition of flat carbon. The technique was used to reinforce an air cooler at Nogent sur Seine power plant where 1,700 m of carbon were laid in 10 weeks.
  • Demolition without explosives : the company is also competent in industrial chimney demolition, as the projects undertaken for Esso in Port Jérôme and in Dunkerque, Champagne and Albi thermal power stations confirm.


  • Containment structure

    We built an experimental model of a reactor containment building on a 1/3 scale for EDF R&D
    The Nuclear and Industrial Division was appointed by EDF to build a double-walled reactor containment structure model on a 1/3 scale. This structure will enable us to study aging behaviour in the French nuclear sector's containment buildings.

  • Optimized organization of multi-site projects
    Optimized organization of multi-site projects

    The Nuclear and Industrial Division is in charge of multi-site changes for EDF (building gas plants, reinforcing pillboxes, post-Fukushima road and network maintenance etc.). To meet the demands of these complex and essential projects, we have set up a specific organization comprising a project unit on the Eiffage Campus in Vélizy-Villacoublay and a number of operational teams.

  • Cranefree Gravity®
    Cranefree Gravity®

    This ground-breaking gravity base foundation for offshore wind turbines patented by Norwegian designer Seatower was built of prestressed concrete in Le Havre. The steel met mast on top was constructed by Eiffage Métal's Belgian subsidiary Smulders.

    Gardanne is France's highest chimney. We replaced the internal lining to a height of 100 m, with core aeration, in only 10 weeks.

    Constructing a combined gas cycle (CGC)

    This 5th installment of Blénod lès Pont à Mousson thermal power plant will emit no sulphur dioxide (SO2) and very little nitrous oxide (NOX) and carbon dioxide (CO2). The plant is equipped with a combustion turbine, steam turbine,  a boiler and transformers.
