Decisions are only as robust as the advice and land they’re built on. So, we look at your project’s success from the ground up. Our geotechnical team specialise in providing practical advice and engineering solutions that form the foundations for successful residential, industrial and land development projects.

We work closely with you to determine what level of investigation, analysis, design and reporting is required for a successful outcome. We help you understand how geotechnical conditions influence your development; and by leveraging our many other in-house experts in site and land development, we advise on the most practical, innovative, and effective solutions to reduce or eliminate risk.

Our expert team of geotechnical engineers and technicians have considerable experience working on a diverse range of projects across the South Island and enjoy the challenge of New Zealand’s variable geological environment.

With offices in Christchurch, Nelson, Queenstown, Wānaka, Rangiora and Hokitika, our geotechnical services are available for projects throughout the South Island.
