Geotechnical Investigation

A well-planned, tailored geotechnical investigation at the early stages of a project lays the foundation for successful delivery. By developing accurate ground models that reduce subsurface uncertainty and identify geotechnical risks, we empower our clients to make informed design and construction decisions—mitigating unforeseen issues and improving project outcomes.

TERRATECH has a proven track record in delivering both straightforward and complex investigations across a broad spectrum of projects—from single residential lot classifications to major infrastructure and nationally significant developments.

We draw on a wide array of investigation techniques to suit varied site conditions, access constraints, and technical requirements. Our strong industry partnerships and practical, hands-on approach allow us to offer competitively priced services without compromising on quality. All investigations are executed under the supervision of senior technical personnel and in full compliance with AS 1726-2017.
