Ertech is an employee-owned engineering construction contractor with over forty years of experience building and renewing critical infrastructure across Australia. The company operates in urban, regional, and coastal communities, delivering projects in the transport, defence, resources, and marine infrastructure sectors. Its structure as an employee-owned business is central to its model, with every team member invested in client success and the company approaching each project collaboratively.
The company's technical capabilities span civil and electrical engineering, multi-disciplined infrastructure construction, and near-shore marine solutions. Ertech is a self-performing contractor, meaning it directly undertakes the work it commits to. It operates through several specialist divisions, including Geomarine for near-shore marine work, Groundex for engineering ground solutions, Fortec for structural and remediation services, and Yaraandoo, an Indigenous-owned contracting specialist.
Key project areas include transport upgrades connecting communities, defence facilities, resource projects, and marine infrastructure serving coastal regions. The company prioritises fairness and transparency with clients and focuses on sustainable growth and long-term relationships built on trust and consistent delivery.
