Geophysics

Ground insight that drives safer, smarter decisions

We make the subsoil visible, using advanced geophysical imaging to help you understand ground conditions, manage risk, and keep your project moving. From 3D subsurface models to real-time monitoring, our solutions provide a complete view of the ground beneath your site, supporting safer construction and better design decisions.

With over 25 years of experience and a strong presence across Australia and New Zealand, our local team delivers fast mobilization, deep technical expertise, and tailored solutions for transport, energy, urban, and industrial projects. We combine proven conventional methods with patented innovations like Cyljet and Sissterra to solve complex challenges — even in hard-to-access or high-risk environments.

Backed by global R&D, a dedicated equipment fleet, and active contributions to industry standards, we deliver practical, future-ready geophysical solutions that give you clarity, control, and confidence from the ground up.

Conventional geophysics

Optimised solutions to meet all your needs, from data collection to data interpretation

Our expertise in geology and applied geophysics gives us the ability to support and advise you on:

Optimizing your projects through subsoil visualization
Ensuring the security of people and property
Characterizing the subsoil in urban, mountainous, coastal, river and other environments that are not easily accessible

Cyljet

Unique method for optimization of jet grouting works

Cyljet is a patented Sixense technology based on the Electric Cylinder method. It enables non-destructive, in-situ 3D investigation of jet grouting columns using a multi-filament cable with embedded electrodes. By measuring and processing the electrical potential differences, Cyljet accurately maps the shape and size of the injected column — without the need for excavation.

Why use Cyljet?

Significant cost savings through precise calibration of injection parameters
No excavation required to verify injection quality
Fast results — data delivered in under 48 hours
Robust and proven — trusted on over 4,000 columns worldwide
Supports real-time quality control during both test plots and active work phases
Over 4,000 columns measured worldwide

Sissterra

Passive seismic imaging to manage underground risk, even in hard-to-access zones

Sissterra® is a turnkey passive seismic solution that uses ambient noise, generated by human activity, to build a detailed 2D or 3D image of the subsurface and monitor its dynamic evolution over time.

We manage the full process, from scoping to actionable insights:

Definition of objectives and acquisition parameters
Data acquisition, processing, and visualization (2D & 3D)
Diagnostics, risk assessment, and decision-making support
