Services
Horizontal Directional Drilling
Our directional drilling services enable precise underground utility installations without disruptive excavation. We specialise in navigating complex terrain across the Northern Territory for telecommunications and infrastructure projects. This method minimises environmental impact while ensuring accurate placement of conduits and cables.
Fibre Jointing and Splicing
We provide precision fibre optic splicing for network upgrades and NBN infrastructure projects. Our technicians ensure seamless connectivity through fusion splicing techniques that maintain signal integrity. This service supports high-speed telecommunications networks across remote Northern Territory communities.
Underground Asset Location
Our DBYD-accredited asset location service identifies underground utilities to prevent damage during excavation. Using advanced detection equipment, we map existing infrastructure for safe project planning. This critical service ensures compliance with safety regulations across all project sites.
Cable Hauling
We install telecommunications cables through trenching and directional drilling methods. Our team manages cable hauling operations for NBN network expansions and infrastructure upgrades. This service ensures reliable connectivity solutions for urban and remote locations.
Hydro Excavation
Our hydro excavation service uses high-pressure water to safely expose underground utilities. This non-destructive method creates precise trenches for infrastructure projects while protecting existing assets. It's ideal for sensitive areas requiring accurate excavation.
