UNderground construction

Thanks to our long standing and continuous updated experiences in underground construction we cover all aspects of conventional and mechanized tunneling:

  • Mechanized drift in unconsolidated and hard rock
  • Conventional drift
  • Raise Boring and shaft construction
  • Injections
  • Construction logistics

Well-trained engineers with their draft teams make it possible to perform tunnel projects of all sizes qualified and efficiently. An extensive machine and equipment park as well as experienced staff at all levels create the base.
