Expertise in materials and drilling fluids to support your worksites

The Soletanche Bachy group’s materials laboratory means you benefit from the best range of materials and drilling fluids in terms of value for money and environmental impact. Our experts analyse specifications, research materials and suppliers, conduct trials and tests, and develop mix designs for concretes, grouts, bentonites and polymers. When launching the works, they also ensure that the materials deliver the expected level of performance.
The Soletanche Bachy materials laboratory consolidates all the Group’s know-how in EXEGY by Soletanche Bachy low-carbon solutions.


In the 1970s, Soletanche Bachy developed the Hydrofraise®, a benchmark machine for boring diaphragm walls.
We have been constantly developing it since its creation. It is now available in several versions:

  • compact for work with limited headroom,
  • containerisable to reduce shipping time and carbon footprint with a gripping kit for very hard ground,
  • or equipped with an electric power pack, or even all of these at the same time.
