Our Geotechnical team provides ground engineering to hazardous, unstable and geologically active cliffs that can pose significant risks to infrastructure and transport networks.
Ground stabilisation and rock control. Our knowledge of rock types and sites allows us to select machinery and resources to complete the project. We have experience with the full range of anchor and netting types. We can assist clients and consultancies with design and constructibility to complete the project efficiently.
Our trained and experienced rope access crews work with expert supervisors who have been working in these hazardous environments for many years.
Our areas of specialist expertise include:
- Drilling and rock anchoring
- Rockfall mesh
- Rockfall catch fences & hybrid attenuation drapes
- Rock scaling, explosives & blasting
- Shotcreting
- Grouting
Our clients include:
KiwiRail, NZTA, Downer, Canterbury Earthquake Recovery Authority, SCIRT, Fulton Hogan, Wellington City Council, Capital Journeys, Trustpower, Porirua City Council, Meridian,sGreater Wellington, Christchurch City Council, NCTIR and Port Hills Geotechnical Group.
