Trenching That's Done to Spec
Trenching for underground cables may sound straightforward, but there’s a lot riding on the details. Depth, alignment, separation from other services and backfill quality all play a role in performance and compliance.
Whether you're laying NBN, electrical, water or data lines, poor trenching can lead to delays, rework or even safety risks. That’s why it’s so important to work with experienced operators who know how to interpret site plans, navigate challenges and deliver consistent results. Jobs are completed using well-maintained machinery and a careful, methodical approach—no shortcuts or guesswork involved.
For fast, professional cable trenching across the Tweed Coast, give us a call and talk to someone who understands what your site needs.
Frequently Asked Questions
How deep should underground cables be buried in Australia?
In Australia, the minimum burial depth for underground cables varies depending on the type of cable and its location. Generally, electrical cables must be buried at least 600mm deep in areas accessible to vehicles or heavy machinery and at least 450mm deep in pedestrian-only areas. Communication cables may require different depths. Depth guidelines are outlined in Australian Standards (AS/NZS 3000) and must also take into account the risk of interference with other services. Always consult site-specific plans and regulations.
Can I install underground power cables myself?
While it may be tempting to DIY underground cable installation, it’s not recommended unless you’re a licensed contractor. Electrical and communication cables must be laid according to strict safety regulations and must be inspected and certified. Incorrect installation can result in electrical faults, damage to surrounding infrastructure or serious safety risks. Hiring qualified professionals ensures compliance, avoids costly mistakes and speeds up approvals.
Do underground cables need conduit?
In most cases, yes—underground cables should be installed in conduit to protect them from moisture, mechanical damage, root intrusion and shifting soils. Conduits also make future upgrades or cable replacements easier without the need to re-trench. The type and rating of the conduit depends on the cable type and installation environment. PVC or HDPE conduits are commonly used for both electrical and data lines in residential, commercial and industrial applications.
