Non-destructive excavation is a method of digging that minimises the possibility of damage to any underground services or anything within the project site such as tree roots. This method is also known as Hydro Excavation or Vacuum Excavation because a high pressure water unit and a high flow vacuum unit are utilised to carefully dig as needed. Non-Destructive Excavation is used during the locating operation to assist in discovering underground assets, and when the underground assets require exposure.
This is a technique known by many names, these include,
- Service Locating
- Utility Locating
- Digital Locating
- Inductive Locating
- Conductive Locating
No matter what name it is known by, basically we locate a point anywhere along a buried service and connect a device that sends a radio signal along the underground cable casing or piping, as the case may be.
Above ground we can then detect this radio signal and follow it along the subsurface asset’s entire length allowing it to be accurately mapped.

Ground Penetrating Radar
The ImpulseRadar PinPointR offers a clear and dependable way to quickly and easily locate, avoid or map underground utilities with the functionality required to meet approved industry standards, whilst offering market-leading performance and data quality.
- True two channel dual frequency antenna system for clear target detection
- Real time sampling for clearer results in demanding environments
Where needed we use equipment that sends and receives radio waves that penetrate the ground surface, including concrete slabs and the like, providing us with images that accurately identify and locate the presence of any subsurface utility within the scanned area.
Acoustic locating works in situations that require the location of non-conductive utilities. We are able to accurately map these utilities using equipment that creates sound waves along the utility. These sound waves are then detected and traced along the path of the utility.
