Underground conduit protects telecommunications cabling from moisture, rodents, ground movement and future digging. It also lets cables be replaced or upgraded without re-trenching.
Things to think about before the trench closes
- Adequate conduit size for the intended cable, plus room to pull spares.
- Sensible depth — deep enough to be safe from garden work and future landscaping.
- Draw strings left in place so future cables can be pulled through.
- Sweeps rather than tight bends at direction changes.
- Separation from power and other services per applicable installation practice.
Common use cases
- Lead-in from the street pit to the property boundary or house.
- Between a house and a detached studio, granny flat or shed.
- Across driveways where later access will be difficult.
Note: Specific depth, separation and marker-tape requirements vary by location and cable type. Confirm with a registered cabler for your job.
