OUR TRENCHLESS EXPERTISE IN UNDERGROUND
PIPEWORK & DUCTING INSTALLATIONS
GENERAL HDD
Horizontal Directional Drilling (HDD) is the trenchless installation of pipework or ducting using a drilling machine. CDS has a range of drilling machines to suit all applications.
DRILLING IN ROCK
CDS has a number of fluid driven mud motors which enables installations in some of the hardest rock formations found in New Zealand.
CURVED ALIGNMENTS
HDD’s ability to accurately drill horizontal and vertical curved drill alignments is essential when trying to navigate around or under obstacles.
SENSITIVE ENVIRONMENTS
CDS has a proven track record working in or around and drilling under sensitive environments such as streams, rivers, estuaries, harbours and bays.
PIPE BURSTING / SLIP LINING
An existing host pipe can be used to pull though a new PE liner pipe, either fitting inside the existing pipe or installing a larger diameter pipe using one of CDS’s bursting tools custom designed for that purpose.
LOW GRADE INSTALLATIONS
CDS can accurately complete installations of both gravity sewer and stormwater pipelines at grades lower than 1%.

LEADING THE WAY IN DRILLING SINCE 1992
CDS was established by the Clough family in 1985, purchasing its first drilling rig in 1992.
CDS’s technical expertise in directional drilling has grown year on year and is now a leader in the industry with extensive local knowledge that is critical to success. CDS has never been afraid to step up to the mark for the more technical, high risk, drilling installations and prides itself at never walking away from a project until the pipe is underground and our client happy.
