Our geotechnical engineers work closely with clients to provide accurate data, rapidly and within budget.

Targeted investigations are vital to solve geotechnical challenges and to ensure the safe and efficient development of sites.

We design and plan investigations carefully and use the latest techniques to produce the required results, cost-effectively. All data gathering and analysis is supervised by our professional team and is supported by our quality assurance and environmental management systems.

We provide a wide range of services, tailored to suit clients’ needs, including:

  • Ground investigation to provide factual data only
  • Ground investigation to install monitoring systems to assess ground gas, ground water and ground movement
  • Detailed site investigation for geotechnical analysis and design
