Utility Location Central Coast

Frequently Asked Questions

Q: Do I need professional utility locating if I have 'Before You Dig' plans?

Yes. ‘Before You Dig’ (BYDA) plans are indicative only and often lack precise depth or updated alignment data. They do not show private services or changes made after the original installation. Professional Electromagnetic Locating and GPR are required to verify the exact location of assets before any excavation begins to ensure site safety.

Q: Can Ground Penetrating Radar (GPR) see through wet soil?

GPR performance can be affected by soil conductivity. In Australia, sandy soils provide excellent GPR clarity, while heavy, saturated clay can limit the radar’s depth. Our technicians use a combination of GPR and Electromagnetic Locating to ensure accurate data regardless of ground conditions.

Q: What is the difference between active and passive locating?

Passive locating detects signals already present on a line (like 50Hz power). Active locating involves us manually applying a specific frequency to a line via a transmitter. Active locating is far more reliable for distinguishing between crowded utilities in complex environments.

Q: Does CCTV pipe inspection find leaks?

CCTV is a visual diagnostic tool. It can identify cracks, holes, and root penetrations that are common causes of leaks. While it doesn’t “sense” escaping water, it provides the visual proof needed for SMBs and homeowners to execute targeted repairs.

How accurate is your Concrete Scanning service?

Our high-frequency GPR concrete scanners are incredibly precise, typically pinpointing rebar and conduits within a +/- 10mm to 20mm margin. This level of accuracy is essential for the building industry when performing core drilling or structural modifications.
