Our geotechnical engineers apply modern tools and methodologies to model, analyse and predict the behaviour of what lies beneath the surface.

From single projects to large scale programs of work, geotechnical engineers are often required to provide solutions in environmentally sensitive, unstable or highly complicated environments. The more ground knowledge you have at a site, the better the outcome of your project.

At Tetra Tech Coffey, we have teams of experienced geotechnical engineers across Australia, New Zealand and the Pacific region. Our work focuses across several services including:

  • Geophysics
  • Deep foundation
  • Groundwater
  • Ground improvements
  • Pavement
  • Slope Engineering
  • Temporary works
  • Earthquake engineering
  • Expert witness

With a proven track record of success, our geotechnical consultants can provide innovative recommendations and solutions for your project, no matter the scale of work required.
