Who we are

About us

Specialist Geotechnical and Geo-Environmental Consulting

Regional Geotechnical Solutions is a specialist geotechnical and geoenvironmental consulting company dedicated to servicing the regional NSW market. Our vision is to be the recognised leaders in providing quality, specialist geotechnical consulting services to regional NSW and beyond, and in doing so improve the standard of  geotechnical consulting service available to regional areas.

We focus on working with our clients to achieve the best outcome for their project by optimising the use and management of ground conditions and ground related risks by:

  • Thoroughly understanding the needs and objectives of our clients and thier projects;
  • Gaining a thorough understanding of geotechnical site conditions, and associated risks and opportunities;
  • Communicating ground related risks and opportunities clearly with our clients;
  • Providing solutions;
  • Providing the best possible service;
  • Teaming with other companies and consultants to “fill the gaps”;
  • Working safely at all times;

Our business is based on providing our clients and projects with regionally based, experienced, capable and qualified geotechnical professionals who are familiar with the local ground conditions and are familiar with the needs of local clients.

Solutions: Our focus on providing solutions differentiates us from many geotechnical consultants operating in regional areas. We do not just provide test results or generic site reports based on broad correlations, we provide a specific appraisal of the ground conditions and the project, and provide solutions tailored to the issues involved at each site. We add value to our clients projects by being part of their team and providing advice and input to the decision making process.





Our People





Steve Morton

Principal Geotechnical Engineer

Steven is a Principal Geotechnical Engineer with over 30 years of consulting experience.  He is a Member of Institution of Engineers (Australia), and Chartered Professional Engineer, and is registered on the National Engineering Register (NER).

He began working as a geotechnical consultant with Coffey & Partners in 1988. From 1988 to 2010 he undertook many geotechnical and environmental investigation and design projects including roads, railways, landfills, contaminated sites, deep excavations, landslides, buildings and urban developments. The majority of his career has been spent providing these services in regional NSW and in doing so he became aware that the particular needs, flexibility, and diverse range of skills required to service regional areas were not adequately addressed in the geotechnical consulting market. In 2010 he established Regional Geotechnical Solutions, a consulting firm focused on providing high quality geotechnical consulting services to regional centres. He currently works on a broad range of geotechnical projects including road rehabilitation, pavement design, slope stability, and geotechnical foundation investigation.
