Answering Common Questions About Horizontal Directional Drilling In Australia

Posted on by Olive Nguyen

At AV Drilling, we are experts in the specialised field of horizontal directional drilling in Australia. As this is a field that requires specific understanding, expertise and experience, there are some common questions that may arise. Here are some frequently asked questions about horizontal directional drilling.

What is Horizontal Directional Drilling?

Horizontal Directional Drilling (often shortened to HDD) is a trenchless technique used for installing underground utilities. These utilities can include conduit, cables, pipes and more. The process involves a channel being drilled beneath the surface of an area with minimal disruption to the surrounding environment.

What Is The Process For Horizontal Directional Drilling?

First, a pilot bore is guided by a special device that sends an electronic signal through the drill head. Then, the pilot hole is reamed until it reaches the set diameter before conduits are retracted into the bore.

What Kind Of Preparation Is Needed For Horizontal Directional Drilling

First, all of the necessary permits and approvals must be obtained. Before drilling can commence, all underground utilities must be mapped to avoid interrupting services such as gas, electricity and water, damaging any existing assets, as well as maintaining the safety of anyone on or near the drill site.

What Are The Bore Hole Capabilities Of Horizontal Directional Drilling

Horizontal directional drilling can be performed in a range of diameters, depending on what is required. At AV Drilling, our borehole capabilities vary from 50 to 600mm in diameter.

What Is Horizontal Directional Drilling Used For?

Horizontal directional drilling is typically used for installing a wide range of pipes, cables, conduits and utilities. It’s usually used over longer distances and commonly employed when drilling under or beside roadways and other infrastructure.

 

What Types Of Projects Typically Require Horizontal Directional Drilling?

Horizontal Directional Drilling has a range of potential uses:

  • Projects that require drilling over long distances
  • Projects taking place in areas that are considered environmentally sensitive
  • Projects that require drilling but must avoid current root systems, soil or anything else below the surface being damaged
  • Projects that are not suitable for open-cut solutions because of roadways, retaining walls, footpaths, water catchment areas and other above-ground concerns.

What Kind Of Soil Conditions Are Appropriate For Horizontal Directional Drilling

Horizontal directional drilling can be used for a wide range of subsurface conditions, from soft, loose sand to hard rock. So long as the proper precautions, procedures and equipment is used, HDD can be successful in most types of ground.
