Geotechnical Drill Rigs by Geoprobe®

Advancing the Geotech Industry

In a geotech industry ruled by rate-per-foot, Geoprobe® geotechnical drill rigs capable of swiftly sliding from rotary to automatic drop hammer, even to CPT or direct push — without having to move drill mast or machine — position you for increased production and profit.

Use the centerline head side shift on our geotechnical drill rigs to simplify traditional geotech techniques such as:

  • Augering
  • Mud rotary
  • SPT
  • Shelby tubes
  • Hard rock cores
  • CPT

Veteran drillers appreciate the attention to features addressing their field needs while the simplicity and safety of the geotechnical drill rigs mean your new drillers will quickly travel the learning curve thanks to:

  • Digital readouts providing instant feedback
  • Safety enhancing features
  • Easy operation, building confidence
  • Availability of training options

Owners depend on our ongoing commitment to innovation and industry-leading customer support to reliably ramp up daily production and geotechnical drill rig utilization rates.

“Our Geoprobe® has exceeded production of our other rigs due to its versatility in sampling types and ability to handle drilling in hard clay and limestone. We can easily switch from continuous sampling with Shelby tubes, to blow counts, to auger drilling with efficiency. It is neither too large or too small to meet our needs, but instead perfectly fills the void. It has met the high demand of drilling thousands of borings and remains extremely reliable.”
