Construction Drilling

 

New world retaining wall, Nelson 

Construction drilling primarily involves the installation of rock or soil anchors that are used to retain or stabilise the surrounding landscape prior to building.  The Hydrill 200 and Hitachi MultiDrill are ideally suited to this type of work.  The Hydrill 200 has been designed to fit inside the cage of a Tadano aerial platform, which has a 12m reach.

CW Drill has recently completed a construction project , in association with a joint venture between MWH NZ Ltd and Fulton Hogan.
