Hagstrom Drilling have extensive geotechnical drilling experience across Australia in different geological and site conditions.   

Drilling Contractor Services - Geotechnical

Quality of soil samples is crucial in geotechnical drilling and recovery demands a high level of expertise and precision.

Data collected during drilling needs to be accurate because it influences decision making and budget considerations.

Our installation of in-situ geotechnical instruments, such as piezometers, inclinometers and extensometers ensure accuracy without wasting time.

A full range of overburden testing equipment is available with capabilities such as coring and testing on holes up to PQ size to a depth of 250 meters.

Our geotechnical applications typically include infrastructure developments such as;

  • Processing plants and buildings (e.g. LNG, mine sites)
  • Service roads, jetties and wharfs
  • Construction and upgrade of major bridges and roads
  • Construction and upgrade of water supply and tailings dams

Geotechnical drilling techniques and capabilities include:

  • Land and Marine (Jack Up Barge and Marsh Buggy) based  drilling
  • Heli portable, man portable, tracked and skid mounted drilling rigs
  • Wireline diamond drilling NQ, HQ, PQ (Wireline triple tube diamond core drilling in rock)
  • Inclined drilling
  • Mud rotary drilling
  • Air core drilling and sampling
  • Hollow flight and Solid stem continuous augers
  • Hollow flight continuous coring 
  • In-situ instrumentation installations
  • Standard Penetration Tests (SPT)
  • Thin wall tube samples (U63 tubes)
  • Shear Vane Test
  • Piezometers
  • Pressure meter tests
  • Permeability tests
  • Piston Sampling

  • Symmetrix overburden drilling
