Services

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

TERRATECH is a civil and geotechnical advisory company that provides geotechnical solutions across Australia for the benefit of our clients and the community. 

TERRATECH’s head office is located in Adelaide, South Australia, and the company offers a wide range of specialised services. With strong expertise and flexibility, TERRATECH is equipped to handle projects of all sizes, from small to large, across various industry sectors.

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.

Our Geotechnical Investigation Capabilities Include:

  • Desktop Studies and preliminary geotechnical assessments

  • Site Walkovers and detailed geological mapping

  • Investigation Planning, Scoping & Management for efficient delivery

  • Geotechnical Risk Assessments to support early-stage feasibility and design

  • Geo Data Management and interpretation for subsurface modelling

  • Detailed Geotechnical Logging of soil and rock profiles

  • Field Investigations & In-Situ Testing (SPT, shear vane, permeability, etc.)

  • Cone Penetration Testing (CPT) for high-resolution profiling

  • Dynamic Cone Penetrometer (DCP) Testing for quick strength assessment

  • NATA-Accredited Sampling & Laboratory Testing of soil and rock materials

Geotechnical Analysis and Design

At TERRATECH, our experienced civil and geotechnical engineers work collaboratively to develop subsurface models that inform practical, cost-effective design solutions. We integrate deep technical understanding with hands-on site knowledge to help our clients manage geotechnical risk from planning through to delivery.

Using a combination of in-house developed tools and industry-standard software platforms, our team tackles a wide range of geotechnical challenges with precision and agility. Our integrated approach allows us to contribute effectively within multi-disciplinary design teams—enhancing design efficiency, constructability, and project outcomes.

Our Geotechnical Design Capabilities Include:

  • Foundation Engineering – Design of shallow and deep foundations tailored to variable soil conditions

  • Ground Improvement & Soft Soil Solutions – Including surcharge, preloading, and reinforcement systems

  • Numerical Modelling – Finite element analysis for stress-strain, settlement, and stability scenarios

  • Earthworks & Construction Support – Ground assessments to inform earthworks planning and staging

  • Settlement Prediction & Assessment – Including primary and secondary compression behaviour

  • Feasibility & Risk Studies – Preliminary assessments to guide early-stage project planning

  • Retaining Wall & Excavation Support Design – Structural design of gravity, cantilever, or anchored systems

Construction Phase Support

At TERRATECH, we provide specialised geotechnical support throughout the construction phase, ensuring that ground conditions are properly assessed, monitored, and managed to meet both safety and specification requirements.

Our services are grounded in practical experience and technical rigour, supporting everything from bulk earthworks to foundation verification, working platform design, and real-time site monitoring. Whether you're working with variable ground conditions, managing groundwater impacts, or constructing critical infrastructure, our team delivers the insight needed to keep projects moving efficiently and compliantly.

Our Construction Support Capabilities Include:

  • Bulk Earthworks Supervision: Level 1 and Level 2 supervision in accordance with AS3798-2007

  • Subgrade Assessment: Evaluation and improvement strategies to meet project-specific performance requirements

  • Material Compliance & Sourcing: Assessment of site-won and imported materials for compaction and suitability

  • Temporary Works Advice: Retaining systems, working platforms, groundwater management, and stabilisation solutions

  • Foundation Verification: Onsite confirmation of founding conditions and pile integrity testing

  • Slope Risk Assessment & Mitigation: Analysis and monitoring for cut/fill stability during staged construction

  • Instrumentation & Monitoring:

    • Groundwater levels

    • Slope movement

    • Vibration

    • Earth resistivity (for electrical earthing or geophysical considerations)

  • Piling & Earthworks Supervision: Ensuring specification compliance and ground risk management during critical construction phases

  • Working Platform Design & Certification: Safe and compliant designs for pile rigs, cranes, and other heavy plant
