Excavation and construction projects demand thorough groundwork, with one crucial aspect being the accurate location of underground utilities. Failure to precisely pinpoint these utilities can result in major disruptions, costly repairs and accidents. In Melbourne, there has been increasing use of non-destructive digging (NDD) to investigate underground utilities without causing harm.
What is Non Destructive Digging (NDD)?
Non-destructive digging (NDD) is a method employed to investigate and uncover underground utilities without causing damage. Specialised equipment is used to create a slurry mixture of water and air, effectively loosening the soil. This loosened soil is then suctioned away via a vacuum system, allowing operators to accurately locate buried utilities.
NDD stands as an efficient alternative to conventional digging techniques like mechanical excavation or manual digging, which pose a higher risk of utility and area damage.
Benefits of performing Non Destructive Digging
- Precise targeting and identification of utilities
- Minimising utility damage risk
- Cost reduction in repairs
- Decreased downtime
- Enhanced construction confidence
- Safe operation around critical underground utilities
While traditional digging methods often result in significant delays, NDD provides accurate outcomes in a shorter time frame. Additionally, NDD prioritises worker and community safety, mitigating accident and injury risks.
When is Non Destructive Digging used?
- Locating underground utilities
- Excavating in sensitive areas
- Debris removal and drain cleaning
- Installing underground infrastructure
What are the different types of Non Destructive Digging?
Hydro Excavation
This method uses high-pressure water to loosen soil, creating a slurry mixture that is then vacuumed away, ensuring a clean excavation site. At Teoma, we utilise high-pressure water and subsequent vacuuming into a holding tank to create a cleaner worksite and reduce the risk of damage to existing underground infrastructure.
Vacuum Excavation
Using a vacuum system, this method effectively removes soil and debris from the excavation site, particularly suitable for both wet and dry materials.
Air Excavation
Compressed air is utilised to loosen soil, creating a vacuum through which soil is removed, facilitating precise underground utility location.
