Construction Drilling

 

New world retaining wall, Nelson

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

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