  • Be aware of all hazards related to geologically unstable areas before you start drilling your tunnel!
  • Slash the number of boreholes by drilling at meaningful locations only!
  • Detection of faults and decompaction zones
  • Assessment of mechanical rock properties
  • Recognition of karstified zones
  • Delineation of the bedrock surface
  • Area-wide investigation
  • Environmentally friendly – no or negligible field and crop damage
  • Applicable also in urban areas
  • Fast field data acquisition, daily progress 1 – 2 km
  • Readily available evaluation results within 2 – 3 days
