Case Studies

A landslide in 2013 closed State Highway 6 in the Haast Pass, and the installation of a three-attenuator rockfall protection system that followed had to be completed on a slope that was still failing. Doing so safely came down to daily construction decisions made on site and the experience and tenacity of our crew.

Geovert has added the PANDA® Variable Energy Dynamic Cone Penetrometer to its geotechnical investigation capability. On Mohaka Coach Road in Hawke’s Bay, it allowed WSP to characterise a landslide face that a drill rig or CPT vehicle could not have reached in a useful way.

Geovert has been delivering rockfall mitigation and geotechnical services at the Hoover Dam for the US Bureau of Reclamation since 2019. This case study looks at what working at one of the world's most recognised infrastructure sites demands, and what years of sustained performance there demonstrates about how our team operates.

A multiple bench scale instability at Rio Tinto's West Angelas iron ore mine blocked access to high-grade ore below. Geovert's design-build approach used top-down rope access construction to install an anchored mesh system to safely stabilise the highwall.

A technically demanding urban slope stabilisation for Wellington City Council, requiring a purpose-built scaffold system, three drilling methods in combination, and asbestos management, all with a live road below

Replacing 60-year-old rockfall barriers at Fremont Canyon required working within location constraints that defined every solution, from the custom lower barrier to the zip-line system that removed 700 cubic yards of debris.

When severe weather closed Northland's main highway, the initial emergency response evolved into an 18-month resilience project built on early collaboration.

When Hamilton's new Waikato River Bridge required slope stabilisation on a sheer 30-metre embankment above New Zealand's longest river, Geovert developed the country's first crane-suspended drilling platform for geotechnical construction.

Constructing a 60m deep grout curtain for Australia's tallest RCC dam from within 3.5m galleries on 42 degree inclines - where custom engineering met confined space realities.

Stabilising slopes across 27 km of motorway through faulted and fractured ground, Geovert played a key role in enabling the construction of Transmission Gully, New Zealand’s most ambitious infrastructure project.

After New Mexico's largest wildfire, Geovert's emergency team raced to protect Santa Fe's water supply from devastating post-fire debris flows.

Following catastrophic earthquakes in Christchurch, NZ, Geovert conducted the largest global 3D rockfall modelling exercise at that time.

Geovert installed icefall and rockfall protection at Yellowtail Dam, ensuring safe operations and uninterrupted power generation through custom barriers, scaling, and sequenced installation.
