Potholing for Utility Verification

Once a utility is located by EMF or GPR, the only way to confirm its exact position, depth, and type is through physical exposure. Non-Destructive Excavation (NDE), often called Hydro Vacuum Excavation or Potholing, is the safest and most reliable technique for this critical task.

This process eliminates the risks associated with mechanical digging near live assets, preventing dangerous strikes, major service outages, and costly repairs.

The Utiliseek NDE Commitment:

• Zero Strike Risk: We use high-pressure water and vacuum suction to precisely break up and remove soil, ensuring no physical contact with the buried utility.

• AS 5488 Quality Level A (QL-A): NDE is the only way to achieve QL-A—the highest, most accurate level of utility information, including exact depth and material type.

• Minimal Disruption: The excavation leaves a clean, minimal hole (a ‘pothole’) that is easily reinstated, reducing environmental and site impact.

Our Non-Destructive Excavation utility locating services are essential at every stage of civil, engineering, and infrastructure projects.

Civil & Construction Project

• Trial Pitting: Creating small, strategically placed holes to physically verify subsurface utility plans before major excavation begins.
• Utility Crossings: Exposing existing pipes or cables at points where new infrastructure (e.g., new water main, communication conduit) must cross them.
• Exposing Assets: Clearing soil from around valves, meters, junction boxes, and manholes for access or repair.

Engineering & Surveying

• AS 5488 Compliance: Achieving the necessary Quality Level A data for final design drawings and record-keeping.
• Data Collection: Potholing multiple points along a critical utility to generate highly accurate utility mapping GIS and CAD models of the asset’s trajectory and vertical elevation.

Utiliseek operates a hydro vacuum machine and employs skilled technicians who prioritize safety and precision.

• End-to-End Service: Combine our EMF & GPR Locating services with NDE Potholing for a complete, QL-A certified utility solution from initial mapping to final verification.

• Slurry Management: We handle the full disposal of the excavated slurry in accordance with environmental regulations, leaving your site clean.

• Local Expertise: Serving all project scales from residential builds to major infrastructure across Brisbane, Ipswich and SEQ.
