Rockfall Protection Installation Video

September 11, 2007 rockman Comments Off

Geovert, a specialty design-build geotechnical contractor in New Zealand and Australia has released a video showing the construction of a challenging rockfall protection project. From their YouTube description:

Stockton Coal Mine is situated on the rugged west coast of New Zealand’s South Island, near Westport. Geovert, a design-build contractor specializing in difficult access rockfall mitigation projects, were retained to provide a turnkey solution combining slope protection and stabilisation measures, to manage the rockfall hazard and protect the surrounding environment with a world class design build rockfall protection solution. The barrier was 1.7 kilometres long and follows a ridgeline escarpment, making this the longest rockfall protection barrier in the southern hemisphere. This was one of the largest and most challenging rockfall construction projects completed to date anywhere in the world.
