Traditional Horizontal Directional Drilling

Directional drilling is a process of installing underground services without trenching. Proven to be faster, more cost effective and a lot less disruptive to existing surfaces. Directional drilling / boring is a useful technology, whether installing small, large or multiple conduits.

Advantages include:

  • 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 method
  • 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.·

Displacement Hammers

Our Grundomat displacement hammer is used for trenchless installation of a wide range of pipes, ducts and cables. A displacement hammer is self-propelled, installing utilities in the city, rural areas, parks or major infrastructure under roads, footpaths, driveways and gardens.


  • Quickly and efficiently installs mains and services
  • The bore sizes range from 20mm up to 130mm in diameter
  • Protecting sleeves can be pulled into the bore directly behind the displacement hammer
  • Displacement hammer drilling distances range from two meters up to thirty metres

Vacuum Excavation

Vacuum Excavation or Potholing are the terms used to describe the location of underground utilities via the use of high powered vacuum machinery. Using high-pressure water, vacuum excavation is the safest, most convenient and environmentally friendly way to get a true visual location on underground utilities without the use of traditional digging/trenching machinery.

The demand for this method of excavation has increased significantly being used by Government agencies, major service and network providers and principal contractors.

Vacuum Excavation minimises the risk of damaging underground services, which will cost time and money to repair!


  • Non destructive locating of underground utilities / services
  • Digging of trenches
  • Removal of drilling slurry, muds or water

Under driveways / roads

Do you need to connect power, water or telecommunications from one side of the driveway to the other? HTD Australia has the expertise and machinery to install conduits horizontally under driveways, roads, paths, gardens and carports without any disturbance to existing concrete or paved areas.

By using a displacement hammer we can minimise costs and eliminate unnecessary concrete cutting and trenching through existing driveways, paths, retaining walls and landscaped gardens. This is the most cost effective method to install conduits and pipes around your home or property.

Example - You have decided to install an electric gate to complement your new stencil crete driveway. The electrician installing the gate gives you the bad news that you have no power to connect into on the gates motor side of the driveway.

Option 1: Cutting a strip through your driveway and trenching in a conduit for the electrical cable to run through and concreting back in the trench leaving the driveway looking uneven and non-matching.

Option 2: Calling HTD Australia to drill under your driveway, installing a conduit without any disturbance to the existing driveway enabling the electrician to simply feed the electrical cable through the installed conduit and connecting to the gate motor on the other side.
