Rock & Ground Anchoring

Proven systems, installed by experts.

Even the best-designed structures can shift or become unstable, especially in regions where seismic and other geotechnical factors come into play. It’s no secret that New Zealand’s landscapes are prone to instability, leading to risks that require a robustly engineered solution.

 

BBR Contech offers an array of high and low-capacity, temporary and permanent, rock and soil anchoring solutions for a wide range of ground conditions. We operate under internationally recognised corrosion protection standards and can provide additional strengthening for anchors in difficult ground conditions through the use of high-pressure post-grouting techniques.

 

Typical applications:

  • Tied-back retaining walls and bridge abutments.
  • Basement retention.
  • Restraint against vertical uplift owing to earthquakes.
  • Slope stabilisation.
  • Seismic strengthening.

We can design and deliver highly technical solutions on high-value sites
BBR Contech has installed large capacity anchors for large structures, as well as designing some highly technical solutions for sites with unusual requirements. Our experienced team is used to overcoming challenges, and will work hard to come up with a solution that’s engineered to meet your requirements.

Mt Victoria Tunnel – Anchors

If you’ve ever travelled between Wellington city and the airport, you’ve probably been through the Mt Victoria tunnel – and maybe even participated in the symphony of tooting horns that’s long been customary practice. With more than 620m to cover, there’s plenty of time to raise a tune! Opened in 1931, the tunnel was the first road tunnel in New Zealand to be mechanically ventilated. The technology remains an important feature today, as the tunnel’s now a thoroughfare for about 45,000 vehicles a day, not to mention hundreds of pedestrians and cyclists.
