Trenchless was one of the pioneers of the introduction of Horizontal Directional Drilling into Australia. Since then we have been at the forefront of R & D and the development of methodologies and processes which have subsequently been adopted as the blue print procedures for large scale infrastructure role outs within Australia and Overseas.

Internationally, Trenchless has consulted and supplied specialist services to various multi nationals within world leading infrastructure projects.

In 2002, Trenchless Utilities implemented and demonstrated its expertise when it took part in one of the largest communication projects conducted to that date which involved the installation of 72,000 kilometres of optic fibre linking all the major Indian cities.

  • Horizontal directional drilling is a process where a pilot hole is drilled between two points along a planned route using a guided and steerable drill stem. The installation of a service is then achieved by using the drill string to pull back the service pipe or cable along the route whilst up sizing the hole by reaming if necessary, to the start point of the hole.

  • Among the major benefits of horizontal directional drilling is the ability to trace the drill head using electronic sensors (SONDE) in the drill head and make changes in the alignment of the bore. Tracking the drill head is achieved with a walkover or downhole location system, in which a crew member tracks the bore from the surface. The battery operated SONDE provides depth, location, direction and angle. After analysing this information the drill operator can make steering corrections to keep the drill head on the correct path and avoid existing buried utilities.

    Horizontal Directional Drilling (HDD) is a highly versatile technique that enables the safe installation of Utilities, it is a technique used for installing infrastructure such as telecommunications and power cable conduits, water lines, sewer lines, gas lines, oil lines, product pipelines, and environmental remediation casings. It is used for crossing waterways, roadways, shore approaches, congested areas, environmentally sensitive areas; often a preferred method because it causes the minimum impact on society, Residential locations benefit greatly from this Trenchless keyhole procedure, Heavy Traffic is a global problem and HDD alleviates congestion.

    Environmentally it is the preferred method causing negligible surface disruption and it prevents totally the chance of the production of toxins like sulphuric acid and heavy metal pollution caused by the exposure of potential acid sulphate soils. In some cases it makes it possible to install a utility where it would not be possible by any method, ie where the depth or location of the utility would mean it would be impractical shore or support.

    The flexibility of the steerable navigation make it possible to thread a utility through a myriad of crossing utilities surface and subsurface obstacles by a skilled operator. It is used instead of other techniques to provide less traffic disruption, lower cost, deeper, no access pit, shorter completion times, directional capabilities, and environmental safety.

    • Less disruptive to the public as there is no need to close roads as in traditional open cut methods
    • Little to no reinstatement of job site. As there are only two small pilot holes at either end of the drill system, no grass, driveways or consumers are disrupted
    • No removal of trees or vegetation along bore route which is an advantage in environmentally sensitive areas
    • Faster than open cut trenching
    • Ability to work in confined spaces
    • Able to work in most soil conditions including rock, which eliminates the need for often expensive rock breaking machines and also reduces the time spent in completing the job
  • Horizontal Directional Drilling (or HDD) is a trenchless technology for the installation of Pipe Conduit and cable that utilizes a drill rig to install product pipe with virtually no excavations being necessary.  The drill rig sets up and launches from the surface and pushes drill pipe into the ground to establish the pathway for the product pipe to be installed.  The location of the drill pipe is monitored through the use of a locating device at the front of the drill head.  Once the operator knows where the drill head is, he then controls what direction the drill head goes in by alternately thrusting and rotating the drill pipe in predetermined directions 12 o'clock for up 6 o'clock for down 3 o'clock for right and 6 o'clock for left to remain on a predetermined path.

    Once this pilot bore is done and a path had been established for the installation of the product is achieved by drawing it back in to the hole  the hole may need to be enlarged through a process called reaming.  This process may be done as many times as is necessary to create a hole large enough to pull in the final product pipeline.

    Key Benefits

    • Safer construction method no open trench
    • Minimal site restoration is
    • Minimal environmental impact
    • Reduced traffic congestion
    • In many cases HDD is cheaper and faster
    • Less disruption to the general public
    • Faster process

    SAFETY as the name implies we use Trenchless techniques were ever possible as open trenches are responsible for an extremely high % of work injuries our onsite inspection consists of a full assessment of environmental, quality and HSE requirements, before any onsite works commence. We use site specific SWMS .

    ECONOMICS Reinstatement costs associated with open trench excavation can be as high as 60% of total budget. Directional drilling needs only a single entry and exit point avoiding costly reinstatement.

    ENVIRONMENTAL Because disturbance is kept to a minimum, the impact on the environment is reduced dramatically.

    SPEED This method of operation is considerably faster than conventional trenching which means that the job is completed in many instances without people in the area being aware it has been done.

    We have established a culture of safety within the company that promotes continuous operational improvements. Formal processes are in place to guide all facets of works.

    SOCIAL COSTS The public has an ever-growing awareness of their rights and any effect on their habitat is being contested with ever-increasing vigor. Directional Horizontal Drilling is capable of passing by with little to zero effect on their property or verge.

    TRAFFIC FLOW the social cost brought about by large numbers of people sitting for what amounts to hundreds of thousands of man hours in traffic jams has led to regulations to ensure that these disruptions are kept to a minimum which has led to increasing use of Trenchless techniques.

    SURFACE OBSTACLES As it is possible to drill as deep as 20 meters, surface obstacles Roads, Rivers, Buildings & other Utilities need not be a problem.

Our credentials are based on a reputation as one of the pioneers of the introduction of Horizontal Directional Drilling (HDD) into Australia in 1996. Trenchless was the first company in WA to install Water, Gas and Power Cable by HDD.

Some of the systems and processes developed in those early years have subsequently been adopted as the blue print procedures for large scale infrastructure role outs nationally and internationally. In 2002 Trenchless oversaw and project managed the operation of a fleet of over 100 Horizontal drill rigs involved in installing over 72000km of optic fibre through the Indian sub-continent.

Today the company operates Drills from 10- 30,000 lb capacity and installs pipe and cable for all Utility applications and some Enviro remediation Process. HDD forms part of our specialist equipment fleet and enable us to provide one off crossing small or large and/or full turnkey end to end solution.
