Trenchless Repairs. Maximum Reliability
TVE delivers sectional pipeline repairs using the Trelleborg epros® DrainPacker system—a trenchless, long-term solution for restoring damaged sewer, stormwater, and industrial pipelines. This method is widely adopted by councils and utilities across Queensland due to its minimal disruption and proven durability. All repair activities are fully documented and delivered in accordance with WSA 04-2020 standards, with optional RPEQ oversight available upon request to support technical assurance and regulatory compliance.
