Cable Location

Locating Buried Cables

Cable location identifies the position and alignment of buried electrical and communication cables. Field-based detection methods are used to confirm cable presence and continuity where records are incomplete, outdated, or unavailable.

When Cable Records Are Incomplete

Buried cables are often difficult to identify due to incomplete records, abandoned lines, or dense infrastructure corridors. Cable location helps reduce the risk of damage during excavation, drilling, or construction by confirming cable presence before work begins.

Field-Based Cable Detection

Cable location begins with surface assessment followed by controlled signal application and tracing. Detected responses are verified across the site to maintain continuity and reduce false positives. Execution focuses on repeatable field practices rather than reliance on existing drawings alone.

Documented Cable Locations

Results include marked cable alignments, documented locations, and supporting field data. When required, information can be incorporated into utility maps, reports, or digital models to support coordination and safer subsurface access.

Methods Used for Cable Locating

Cable location uses established detection methods selected based on cable type, access conditions, and site constraints. Methods focus on non-destructive identification and confirmation of buried electrical and communication infrastructure.

Electromagnetic Direct Connect Locating

Transmitter connected directly to accessible cables or tracer wires to send a detectable signal.

Electromagnetic Induction Locating

Surface-applied signal induces response in buried cables when direct connection is unavailable.

Passive Electromagnetic Locating

Receiver detects naturally emitted electromagnetic fields from energized electrical cables.

Ground Penetrating Radar (GPR)

Radar reflections help identify non-conductive or unknown subsurface cables under suitable conditions.

What to Know About Cable Location

Learn more about common considerations when locating buried cables, including limitations and typical deliverables.

Electrical and communication cables can typically be located using electromagnetic methods, depending on accessibility and signal conditions.

Cable location primarily identifies horizontal position. Depth estimates may be possible but vary by method and site conditions.

No. Cable location is performed using non-destructive surface-based methods whenever possible.

Yes. Located cables can be incorporated into utility maps, reports, or digital models when requested.
