Geological and geotechnical hazards arguably pose the single largest risk to civil and mining infrastructure, making the gathering of geological and geotechnical data, in the preparation of accurate and appropriate geotechnical models, indispensable in the pursuit of safe and cost effective structures.

Our dedicated team, of professionally registered engineering geologists, have more than 40 years of combined experience, which they’ve gathered across a variety of geological and geotechnical terrains, enabling them to provide safe and cost effective solutions to a broad range of geotechnical problems.
