Consideration for the city, local residents and the environment

Our company’s technical know-how and ability to meet deadlines make us a strong and reliable partner. Eiffage Génie Civil has put its stamp on a growing number of operations in the foundations sector. Our customers rely on our specialists from the first stages of their complex large-scale infrastructure projects and real estate programmes. Eiffage Génie Civil is called on to take part in structuring projects like the Grand Paris Express.


From special to deep foundation work

Eiffage Génie Civil can respond to all the demands of complex contracts. Our company offers a broad range of fully-controlled techniques and processes, with specific know-how in a number of fields.

  • Retaining walls and foundations : diaphragm walls and foundation bars with bucket and cutter, foundation piles of all types, secant piles and micropiles, anchorage (prestressed tie-rods and nails) soldier pile walls and forepoling.
  • Soil improvement : void filling, ground reinforcement and sealing by injection, jet grouting, specialist ground freezing works.

 

Targeting excellence with latest-generation materials

At Eiffage Génie Civil we have our own cutting-edge equipment to meet the technical challenges raised by major foundations works.

  • 2 complete cutter workshops comprising a MC96 carrier with integrated winding system and a BC40 cutter for the construction of 800 to 1,800 mm-thick diaphragm walls, up to 80 m deep in constrained environments.
  • One compact unit to remove grit from drilling mud, with a limited footprint.

Permanent support from the Group's experts

Whatever the scale of the foundation work, we work as closely as possible to the operational requirements throughout the project. We operate everywhere, in conventional civil engineering and in the building industry, requiring, for example, cast wall supports and injections of all kinds. 

In addition to their own resources, our foundation teams draw on the skills of Eiffage Génie Civil's technical design office and Materials and Innovation department. This guarantees efficiency and reliability in the management of major projects.
