Client Testimonial

“As Project Manager for Fulton Hogan in the Great Southern region for a number of years, I have engaged Great Southern Geotechnics on a number of roadbuilding projects and I highly value the quality, responsiveness, attention to detail and personal service that we receive as a company.

I consider them to be an integral part of our project construction team as they provide independent and competent material testing services that comply with both Australian Standards and Main Roads WA Specifications.

As a company, we can call on their service representatives with issues and they make it their priority to resolve them in a timely manner. I greatly appreciate Great Southern Geotechnics and their staff – I feel like they are an extension of our own staff when it comes to our projects and I would highly recommend their services to the construction industry.”
