What is Horizontal Directional Drilling?
Horizontal Directional Drilling (HDD) is an advanced construction technique, which allows for the installation of pipelines and conduits without the need to excavate trenches. This method involves a drill rig which sits on the ground and drills a pilot hole along a determined path. Once it reaches it’s destination, it enlarges the hole and pulls the pipe in, back towards the drill rig.
Who Are We?
CD Drilling is a trenchless technology company, conducting horizontal directional drilling, rock drilling, service locating and minor civil construction works to install pipelines and conduits for various industries including water supply, wastewater supply, communications, electrical supply, gas supply and mining.
For over 20 years, we have successfully installed assets under rivers, rail lines, roads and environmentally sensitive areas in varying ground conditions including sand, rock and granite. HDD is the preferred method in many situations due to the minimal environmental impact and minimal reinstatement costs.
With our years of experience, CD Drilling delivers low impact, safe and sustainable trenchless installations throughout Western Australia. We pride ourselves on developing solutions to deliver challenging projects efficiently and safely, and as a part of this committment, are certified to ISO 45001, 14001 and 9001 for OHS, Quality and Environmental Management Systems respectively.
Environmental Award – 2020
Our proactive approach to protecting native flora and fauna while installing a wastewater main was recognised in 2020 with the Civil Contractors Federation WA’s environmental achievement award.
This award, part of the CCF WA’s annual Industry and Training Awards program, recognises excellence and innovation in the civil construction industry.
Water Corporation and CD Drilling crews on site in Fitzroy Crossing after successfully installing a wastewater main under the Fitzroy river.
In January 2023, the Fitzroy River Bridge was damaged during a 1 in 100 year flood, which also destroyed the wastewater pressure main attached to the underside of the bridge. Within a matter of months, CD Drilling had mobilised to site, and installed over 600 metres of a new, permanent wastewater main at 30 metres below the Fitzroy River to provide greater protection from flood events.
The timeframe and cost of completing the new permanent installation was cheaper and faster than some of the temporary options being investigated! Repairs to Telstra infrastructure were also able to be undertaken, securing the communications network for the next event. It was a challenge going from concept to delivery on such an important project, but the work was completed without fault.
