What Is NDD (Non-Destructive Digging) And What Is It Used For?

what is non-desctructive digging

Underground infrastructure and under road boring is moving more and more towards the use of Non-Destructive Digging.

This is a method that uses hydro excavation and vacuum trucks as a safer alternative to mechanical digging. 

It involves digging trenches and boring holes in a safe and efficient way around buried services.

It utilises the latest hydro excavation equipment to minimise the risk of damage to underlying utilities. 

Qualified operators make use of the power of water to direct a high-power stream capable of blasting through hard ground, dirt and clay while a separate component is used to vacuum up the waste or slurry. 

Hydro excavation operations are safe and efficient and have a low impact on the environment.

 

The Benefits of Non-Destructive Digging (NDD)

  • Reduces the Risk of Damage – NDD significantly reduces the risk of damage to underlying services, particularly around optic fibre and cable connections to communication systems, pipes, and conduits that contain power, gas and water networks.
  • Widely recognised by gas, power, rail, and construction companies as a safe method of excavating soil when it comes to protecting underground services or assets.
  • The removal of materials such as dirt, sand, and soil exposes the underground utility and a high-power vacuum system extracts and removes the dislodged material to create a clean work site.
  • Waste material is transported to a proper waste disposal facility, leaving the work site clean and clutter-free.
  • Non Destructive Digging has the least impact on the environment when compared to conventional digging techniques. Due to the non-invasive nature of the process, it is one of the most effective and environmentally friendly ways of excavating soil with the lowest risk of damage to utilities and underground assets.
  • The non-mechanical process requires less labour and restoration and is, therefore, more cost-effective.
  • The NDD method is twice as fast as using mechanical excavators, saving time and money.
  • Due to its accuracy, precision, and safety, this technique has become the desired method for many industries.

 

Non Destructive Digging for Commercial and Industrial Use

Pressure Works Non Destructive Digging specialises in providing effective solutions for a wide range of industries including power, gas, water and rail companies as well as schools and councils across Melbourne. 

Highly qualified and trained excavation technicians use the latest technologies and state-of-the-art equipment for the following applications:

  • Hydro Excavation
  • Vacuum Loading
  • Drain and Pit Cleaning
  • High-Pressure Water Cleaning

 

Advantages of NDD Applications

Hydro excavation can assist in detecting underlying utilities such as cables and pipes without causing damage or undue disruption. 

Construction companies, utility providers, and telecommunication companies can all benefit from the use of NDD on their work sites.

This method of digging is highly recommended and the following services are provided by Pressure Works:

  • Power poles and signposts
  • Trenching, service proving, and asset exposure
  • Optic fibre exposure
  • Pier hole digging
  • Post hole digging
  • Root barrier installation
  • Tree removal
  • Deep pier or borehole cleaning
  • Potholing or excavating around power, gas, water, and telecommunications sites.
  • Limited access excavation
  • Safety barrier installation
  • Sewer and water repair excavation
  • Construction site water

Ground conditions in Melbourne can often be harsh which requires effective equipment with the latest technologies to tackle small as well as large projects.  

Hydro excavation trucks are equipped to safely remove all types of debris, leaving a clean work site. 

NDD methods minimise damage to underlying services by digging around underground utilities and using high-power water pressure to expose services. 

Waste material is removed by the use of suction and held in large storage tanks for safe disposal off-site. 

Pressure Works regularly performs Non-Destructive Digging on critical infrastructures such as gas lines, power lines, sewer lines, and telecommunication cables in and around Melbourne.
