Geotechnical Ground Investigation Onshore and Offshore

Mechanical Boreholes

Geocontrole owns a comprehensive set of drilling equipment, with several characteristics, using drilling methodologies appropriate to each kind of intervention.

• Rotary drilling with continuous coring recovery.
• Rotary auger drilling with hollow stem augers.
• Wireline coring system (NQ to PQ diameters).
• Destructive drilling with down the hole hammer or hydraulic hammer.

For geotechnical ground characterization, in situ tests are carried out, in the course of drilling operations.

• Standard Penetration Tests (SPT).
• Menard Pressuremeter Tests.
• Marchetti Flat Dilatometer.
• Shear Vane Test (field vane tests).
• Instantaneous Diagraphy.

To perform geotechnical investigations in aquatic environment, Geocontrole has several support equipment (floating platforms, pontoons and jack-up barge) to carry out jobs in fluvial environments and in nearshore areas.
