Horizontal Drill Services

Horizontal Directional drilling is a process of installing conduit and pipe underground using a trenchless method.  A horizontal directional drilling machine for Trenchless Underground Drilling has proven to be faster, more cost effective and a lot less disruptive to existing surfaces whether installing small, large or multiple conduits. Let our horizontal drilling machine make short work of any task you need completed.

Regional Queensland


  • Trenchless solution for underground installations without disturbing surfaces
  • Savings in excavations and shoring costs
  • Savings in daily reinstatement costs
  • Removes the possibility of trenching-related accidents
  • Less delays due to unfavourable weather conditions
  • No need to apply for road opening permits for public road works
  • Faster and neater, usually requiring less than half the time needed by
    conventional trenching methods
  • Ideal for sites sensitive to surface disruptions, like golf courses, airport
    runways, busy traffic junctions, difficult site conditions, etc
  • Eliminates the need to level and replace/match pre-existing surfaces
  • Cost effective – prices tend to be similar if not less than traditional trenching methods

Recent HDD Trenchless Projects

Woombye Aged Care Facility

8 Bores – 63mm Rising Sewer Main – 800 meters of drilling through a variety of challenging alignments, including bushland, creeks, roads and difficult terrain. Additional precision was required to ensure the rising sewer main pipeline was installed with consistent fall.


110mm Gas Sleeve – 100 meter under-bore beneath an ARTC rail corridor. Our rock-drilling HDD rig was used to successfully deliver this project through hardened sandstone.


6 Bores – 180mm Rising Sewer Main – 380 meters of drilling for a new sub-division.. We tackled a few different scenarios and installed bores beneath creeks, roads and bushland.


16 Bores – 180mm Water Main & 90mm Recycling Main – 750 meters of drilling installed through-out the botanical gardens. These bores required careful consideration of the existing gardens, historical sensitivities and pedestrian traffic.


125mm Electrical and 125mm Communications Conduits – We were engaged to expand the electrical and communications services through-out a variety of schools within South East Queensland. Our bore alignments were beneath buildings and school grounds, and these works required careful safety considerations as school operations were on-going.


9 Bores – 250mm Gas Sleeve – 360 meters of drilling along road verges and beneath roads for the installation of a new gas main. This project involved close collaboration with the principal contractor to ensure smooth delivery.


2 Bores – 125mm Electrical & 63mm Communications – 104 meters of drilling beneath concrete slabs, testing our tracking expertise to accurately maintain the desired bore alignment.


315mm Sewer Enveloper – 70 meters of drilling down an embankment. This project required careful planning and drafted bore profiles to ensure the pipeline was installed to the correct parameters.


9 x 125mm Electrical Conduits – We faced challenging ground conditions and restricted space during the deliver of this project – however we still completed the installation within the set timeframes.
