About

About

We're straight talking civil and geotechnical engineers who are passionate about what we do. 

At TERRATECH, we specialise in geotechnical consulting services that support safe, efficient, and sustainable development across South Australia. Our team of engineers and field specialists deliver detailed site investigations, soil classification reports, and groundwater assessments tailored to the needs of developers, architects, and local government.

Approach to Engineering

At TERRATECH, engineering isn’t just about numbers and compliance—it’s about delivering practical, site-specific solutions that support confident decision-making and successful construction outcomes.

Grounded in Practicality

We understand the pressures of real-world projects: tight budgets, evolving designs, and fast-moving timelines. That’s why our investigations and reporting focus on actionable outcomes—providing clear guidance on earthworks, footing systems, site preparation, and groundwater management that aligns with both engineering standards and builder needs.

Technically Sound, Clearly Communicated

From bearing capacity assessments to groundwater modelling, we apply proven methods and industry best practices. But we don’t hide behind jargon—our reports are written to be understood by all stakeholders, including planners, architects, and certifiers.

Responsive and Adaptable

We approach every site with fresh eyes, not one-size-fits-all assumptions. Whether dealing with reactive clays, variable fill, shallow groundwater, or steep topography, our team tailors each investigation and recommendation to your project’s specific risks and constraints.

Built for Collaboration

We see ourselves as part of your project team. We collaborate closely with structural engineers, civil designers, and approval authorities to ensure our input fits seamlessly into the broader development process.

Team

Rhys Mathews

‘Expert Geotechnical Engineer Committed to Delivering Practical and Efficient Solutions’

Rhys is a chartered (CPEng, NER) and accomplished Geotechnical with diverse experience in civil construction and geotechnical projects across Australia. He possesses expertise in geotechnical engineering principles and civil foundation construction, specialising in geotechnical investigation, design and analysis, piling, ground improvement, and ground support techniques.

My Journey

I graduated with Honours from the University of Adelaide, earning a double degree in Engineering and Geology. Over the course of my career, I have had the opportunity to work with some of Australia’s most respected engineering consultancies, including Menard Oceania and Golder Associates.

My professional experience spans a broad range of sectors—renewable energy, infrastructure, and mining—each presenting its own technical challenges and regulatory complexities. This cross-sector exposure has equipped me with a well-rounded understanding of ground engineering principles and an appreciation for the practical constraints unique to each industry.
