Investigations, surveys and tests for geotechnical, geomechanical and hydrogeological characterization of in-situ rocks and soil.

Assessment of physico-mechanical properties and natural stress state

  • Large size sampling of rock and soil
  • Sampling of cylinders through die-cutting and coring
  • Density and water content tests of soil
  • Load tests on plate (soil and rocks)
  • Large scale tests of compression, shear and swelling
  • Pressiometric and dilatometric borehole tests
  • Single and double flatjack plate tests
  • Overcoring 2D (Doorstopper) and 3D (CSIR, CSIRO) and undercoring tests
  • Hydraulic fracturing tests (HF and HTPF)
  • Dynamic tests on structural elements

Tests and structural controls

  • Sclerometer and SonReb tests
  • Pull-out test
  • Flatjack tests
  • Load tests on micropiles, piles and slabs
  • Pachometer and thermographic surveys
  • Foundation pile integrity tests
  • Ultrasonic tomography testing on masonry, columns and walls
  • Borehole core sampling

Hydraulic tests

  • Pumping tests and slug tests
  • Lefranc and Lugeon permeability tests
  • Flow measurements with tracers and micro impeller pumps

Geophysical surveys

  • T2D and 3D seismic, electric and ultrasonic tomography
  • Georadar (GPR) surveys of surfaces and in boreholes
  • Vibration and noise measurements
  • Sonic coring and dynamic pile testing
  • Borehole logging, sonic (Full Waves), temperature, gamma rays, conductivity, spontaneous potential (SP), optical televiewer surveys (OPTV) and ultrasonic (BHTV) imaging
  • Single and 2D multichannel analysis of surface waves (MASW) surveys
  • Audio-magnetotelluric (AMT) surveys
  • Seismic face surveys of tunnels under construction

Inspections

  • Visual inspections of tunnel lining and structure
  • Excavation profilometry and tunnel lining by means of 2D and 3D laser scanning systems
  • Borehole inspections and surveys with colour television probe
