Geotechnical engineering is the foundation of all infrastructure projects; often, a project’s risk lies in the ground.

Our geotechnical engineers seek to reduce this risk, by investigating and understanding the sites subsurface conditions, and its behaviour under different loading conditions.

How can we help?

Our large team of geotechnical engineers, geologists and engineering geologists have international experience in research, contracting and consulting. We can provide the full spectrum of geotechnical engineering capability, from desk study through field investigation, factual reporting, geotechnical interpretation, stability analysis, foundation assessment, design and supervision.

Our geotechnical services support and complement SLR’s civil and structural engineering, landscape architecture, water resources, environmental science, planning, and transportation services.

SLR's geotechnical services include:

  • Geotechnical investigations & characterisations
  • Pavement evaluation & design
  • Temporary lateral support design
  • Foundation underpinning
  • Ground improvement
  • Dam evaluation & design
  • Waterfront improvements
  • Retaining wall evaluation & design
  • Shallow & deep foundation design and testing
  • Soil & rock characterisation & stability
  • Dewatering design
  • Vibration monitoring
  • Geotechnical construction observation
  • Peer review services

Our team includes
