Drilling & Subsurface Exploration

Because we are a geotechnical engineering firm and perform our own drilling, we have a large advantage over other firms: quality and flexibility. We know that some projects demand quick action, and can work with you to meet tight schedules. Our engineers keep in close contact with our drill teams to ensure that our subsurface explorations obtain accurate and quality data and to modify the scope of a project when unexpected soil conditions are encountered. With more than 25 years of experience, our drillers have been well trained to identify potential subsurface problems and appropriately respond to these conditions.

We offer the following services:

  • Shallow exploration to obtain bulk samples for pavement designs, borrow investigations and potential on-site select material availability
  • portable mobile drills, skid rigs, all-terrain track mounted rigs and barge¬†mounted drill rigs
  • Solid stem and hollow stem auger drilling and sampling, mud and rotary drilling coring and air hammer drilling equipment
  • Drilling and sampling with hand-auger equip
  • Split-spoon samplers, California liner samplers; Shelby tube samples and NX wireline core samples
  • Seismic exploration
  • Test & monitor wells
  • Geothermal well testing
  • Test pits, test borings and core logs are presented visually using AutoCAD
