Geokos Nenzi Glemina drilling rig operating in rock

Nenzi Glemina · Ground investigation

Ground
Investigation.

Direct access to the subsurface, high-quality samples and reliable observations for engineering interpretation.

A complete investigation operation

We do not simply drill holes. We build the evidence for design.

Every programme is adapted to the geology, access constraints, structure and design stage. Our field teams recover, describe and preserve the information that engineers need to understand the ground with confidence.

Scope of work

From access to the final borehole record.

  • Rotary borehole drilling in soil and rock
  • Vertical and inclined drilling
  • Continuous rock coring and core logging
  • Disturbed and undisturbed sampling
  • Trial pits and engineering-geological logging
  • Piezometer installation and groundwater monitoring
  • Lefranc and Lugeon permeability testing
  • Investigation records and engineering reporting

Visible evidence

Recovery, access and documentation matter.

These are not decorative project photographs. They show the quality of the recovered ground record and the conditions our teams are equipped to work in.
