What We Do
We solve geotechnical problems
that last.
GSI are experienced at working in a wide range of locations and conditions. Whether it’s busy urban developments, steep and unstable hillsides or land exposed to weather, we have the equipment, insight and skills to adapt. Wherever there’s a potential risk of unstable ground threatening roads, rail, industry or communities, we step in.
Design
GSI can offer you solutions that not only reduce risk and improve ground stability, they’ll save you time and money. Our team combines design and construction under the same roof, for better communication, faster delivery and full accountability.
We focus on understanding your needs, tailoring solutions that meet your budget and deliver on critical timelines, all while keeping long-term quality at the centre.
Build
Our engineers, operators and specialists are leaders in ground engineering, geohazard mitigation and ground improvement across a wide range of sectors. We use modern technology and sustainable practices to produce durable, practical and responsible work.
From materials to workmanship, quality guides every step and safety is assured with dedicated training and rigorous safety protocols.
Deliver
With thousands of completed projects across New Zealand, Australasia, the Pacific and North America, we have an outstanding reputation for pioneering design and geohazard mitigation. Our goal is always the same: to offer you exceptional value, lasting results and solutions that stand up to the pressures an ever-changing world throws at it.
