With a fleet of more than 40 machines, the strictest safety standards in the sector and international manpower with expertise in complex geological formations, we carry out all types of drilling for geological and geotechnical surveys:

  • Core drilling of various diameters and depths

  • Simple or reverse circulation destructive drilling

Raise Boring

With a fleet of 5 Raise Boring machines, we possess a highly efficient tool allowing us to make 5,000 metres of shafts of various diameters and various depths and dips every year. We also use the Rotary Vertical Drilling System (RVDS) technique to guarantee the verticality and orientation of the shafts and the production of vertical shafts with extreme precision.

In 2018, we acquired a new Raise Boring machine on a par with the best in the world, with a drilling depth of 1200 m and a diameter of up to 7m.

Excavation technique for vertical and angled works, the Raise Borer is a machine for mechanising work to excavate ventilation shafts, waste chutes for mining products, extraction shafts, etc.

This technique has a number of advantages:

  • Safer

  • Eliminates the most arduous tasks

  • Optimised costs

  • Shorter completion times
