Technique

Auger Drilling

Auger drilling is a geotechnical drilling technique that uses a helical screw (auger) to penetrate soil and extract continuous soil samples for investigation purposes. It is widely used for shallow to medium-depth site investigations where soil characterization, borehole logging, and preliminary foundation assessment are required.

Auger drilling is a geotechnical drilling technique that uses a helical screw (auger) to penetrate soil and extract continuous soil samples for investigation purposes. It is widely used for shallow to medium-depth site investigations where soil characterization, borehole logging, and preliminary foundation assessment are required.

Where this technique is applied

  • Environmental drilling – (installing small monitoring wells)
  • Utility installation – (poles, fences, streetlights)
  • Foundations – (drilling for piles — flight augers, CFA piling)
  • Agriculture – (soil sampling, planting)
  • Geotechnical site investigations – (collecting disturbed and sometimes undisturbed samples)
