Our award-winning OnSite trenchless division caters for a wide range of clients, minimising disruption to the client and end user. When it comes to trenchless technology, Horizontal directional drilling is one of the fastest growing innovations.

Advantages of directional drilling

Conventional methods are usually very disruptive, involving exposure to hazards, service outages, environmental concerns and economic viability. On the other hand, Horizontal directional drilling (HDD)

  • usually confines diruption to entry and exit points,
  • is environmentally friendly
  • can be used on different ground conditions
  • less disruption to transport infrastructure
  • a wide variety of uses including pipe installation

Horizontal directional drilling can be a better solution on environmentally sensitive sites that need special protection due to factors such as landscape, history and wildlife.

Direction drilling techniques

Using techniques, including guided auger boring, horizontal directional drilling and pipe bursting, we install new pipelines, cable ducts and refurbish existing pipe networks.
