What we do

Horizontal directional drilling

HDD constitutes an important component of many pipe­ line construction projects. Horizontal directional drilling is more efficient, often more economical, faster and, above all, has much less impact on the environment.

The characteristics of HDD make it the best solution for many customer needs; in some cases it provides the only practical solution. Utilities Infrastructure NZ uses Horizontal Directional Drilling for, among others:

  • Waterways
  • Nature reserves
  • Major roads and traffic junctions
  • Railways
  • Densely populated regions and urban areas
  • Industrial sites
  • Landfalls and outfalls
  • Flood plains and bogs
  • Unstable soil conditions
  • For getting below contaminated ground

What we do

Hydro excavation

Utilities Infrastructure NZ can also provide service locating using vacuum excavating, also known as Hydro excavating, Potholing, Hydro Trenching or Hydro Digging.

It is the process in which a high pressure water jet and vacuum truck is used to create trenching by removing the earth and heavy debris by a powerful suction hose, rather than by manual trench excavation. It safely identifies services such as gas, water, electric, phone & fibre optic cables – preventing possible damage.

This process allows for quick, clean and precise evacuations which require less backfilling, less labour and machinery, with less environmental impact than conventional digging methods. A controlled water jet allows for surgeon-like accuracy. While removing only material necessary for a repair or an inspection with far less material needing to be removed when compared with the bigger, less-than-accurate excavator method.

What we do

Pipe Bursting

Pipe bursting is a trenchless method of replacing existing buried pipelines, such as Sewer, Stormwater and any earthenware or AC (Asbestos cement) and cast iron type pipelines.

This is done without having to excavate any trenches, consequently reducing the cost of expensive reinstatement often associated with the open cut trenching method. “Launching and receiving pits” replace the trench needed by conventional pipe-laying methods.
