CW Drill Projects

This project involved the drilling and installation of 36 anchors to stabilise an existing retaining wall and basement of a home in Kaiteriteri, Tasman after Cyclone Gita.

A series of PQ size core holes through the big landslides after the 2016 earthquakes. ‘Kaikoura EIL Research’ want to understand why this happened to try and help prevent future failures.

Geotechnical project carried out for T&T and KiwiRail. Due to Kaikoura earthquake this tunnel was damaged and the hill was to be cut down to ‘Daylight the Tunnel’, out work was to identify strata.

Project involved extensive Geotech Drilling to understand the formation of work environment, then drilling and installing RB32 anchors through colluvium and into basement rock.

A really interesting project undertaken with Ranui Construction for Ports Of Marlborough. Drilling was in a very tight work-space and at multiple angles to successfully complete the project.

Extensive damage due to Cyclone Gita. Project included earthworks and excavation, large diameter holes for cemented retaining wall posts, drilling and installation of anchors to support completed wall.

Nice to return to a work site where we have done exploration drilling for over 20 years. This project involved drilling a series of holes to intersect an old mining tunnel/drive, 90 metres below the bottom of the old Globe Pit.

Project involved a series of drill holes for geotech purposes to determine liquefaction risks for the new Nelson Airport terminal and replacement DVR. Challenges included working in the landing flight path.

Immediate drilling required in remote and extremely steep country all within typical dense West Coast bush.

Drilling a single core hole in PQ TT to 25 metres and carrying out SPT testing at 75m intervals. Access over busy ski-lanes and soft snow covered ground were just 2 of the challenges.
