Consumer Mains Underboring for Sydney Electrical Projects
Plan a conduit crossing for consumer mains, submains and underground electrical services without cutting a finished driveway.


Consumer-mains and submain routes often cross the exact surfaces owners do not want opened: driveways, tiled paths, concrete slabs and landscaped entries. Underboring can create the crossing while keeping the surface substantially intact, provided the final route and conduit requirements are known.
The electrician or ASP should confirm the conduit size, quantity, draw-rope requirements, termination points and required cover. The excavation team can then plan the pits, bore line and access around those details rather than guessing from a rough distance.
Electrical compliance remains the responsibility of the electrical contractor and network owner. The excavation scope should state where civil work ends and electrical installation begins so the handover is clear.
Site Checklist
- Confirm consumer-mains and submain conduit details
- Mark switchboard and connection points
- Measure the finished-surface crossing
- Scan the bore path
- Agree on handover photos and draw ropes
