Tieleman Excavation & Construction is your all-in-one partner for underground construction projects across WA. As experienced underground contractors, we handle the full scope of work required to install subsurface utilities and services. Our capabilities span from initial excavation to final installation and testing. We perform precision Trenching Services for open-cut installations, as well as advanced Directional Drilling Services for trenchless crossings under roads or sensitive areas. We also excel in Pit & Pipe installations for communications and electrical networks, and follow through with Cable Laying or Cable Hauling to get your power lines or fiber optic cables in place. With Tieleman, every aspect of underground utility construction is covered by one reliable team.
Our underground contracting services support both the mining sector and civil infrastructure developments throughout Western Australia. On mine sites, we construct robust underground networks – from high-voltage electrical feeds powering operations to data and communication lines linking remote facilities. We understand the stringent safety and operational requirements of working on active mining operations and comply with all site procedures. In the civil realm, we help build the backbone of communities by installing water pipelines, sewer systems, and telecom conduits beneath streets and properties. Our crew coordinates with project engineers and other trades to ensure smooth integration of the underground works into the broader project.
Being a full-service contractor, we place a strong emphasis on quality control and safety at every step of underground construction. Our team uses calibrated equipment and adheres to best practices for pipe bedding, cable protection, and jointing (including skilled Poly Welding for HDPE pipes). We conduct inspections – such as checking conduit alignment or pressure-testing pipelines – to verify that installations meet specifications before backfilling. Safety is ever-present: trenches are secured, drill paths are carefully monitored, and work sites are managed to prevent hazards. Furthermore, by entrusting all underground tasks to us, you benefit from seamless coordination and communication. We schedule and execute each phase efficiently, keeping your project on track.
