Geotechnical engineering


Our partner EFLA began operations in 1979 and in 1991, a specific department has been settled to take responsibility for this aspect of the business.

The Geotechnical Department has grown steadily and today it is staffed by a dedicated team of geologists and technicians.

Various projects are handled such as :

  • Site investigation for every type of structure
  • Aggregate testing and analysis at home research laboratory
  • Geotechnical and rock-mechanics consulting service
  • Ground penetrating radar surveys for site investigation, archaeology, etc
  • Assessment of the environmental impact of construction projects
  • Design and project supervision of work on grounding
  • Consulting and research on aggregate and rock materials

Since 2002, HECLA has been assisting the French TSO RTE for the OHL general expertise, mainly for the inspection of foundations and materials. Since 2006, HECLA intervenes in geotechnical missions in collaboration with qualified partners.
