No-Dig Cable Duct Rehabilitation at Energy Plant
McBreen Enviro UK was contracted to restore three 40-metre, 225mm diameter cable ducts on a major energy infrastructure project in Northwich.
The ducts had become unserviceable for housing new high-voltage cables, and traditional excavation was not feasible due to restricted access beneath the plant.
Challenges
- Concrete intrusion from ageing piling
- Crushed sections within the ducts
- Open joints creating potential voids
- Excavation was not possible due to plant layout and operational constraints
Our Solution
Our team implemented a trenchless rehabilitation approach. Robotic cutting removed concrete intrusions and deformities, while Jet Vac cleansing cleared all debris from the ducts.
Structural integrity was restored using 225mm CIPP patch repairs to seal voids and open joints. Finally, each duct was lined with specialist heat-resistant UV resin, providing long-term durability and operational reliability.
Results
The project successfully restored full functionality to all three ducts without disruption to plant operations.
By delivering a safe, efficient, and sustainable solution, McBreen Enviro UK demonstrated the effectiveness of trenchless technology for complex energy infrastructure challenges.
This project highlights our ability to deliver trusted, no-dig duct rehabilitation solutions where traditional excavation is not feasible.
From initial CCTV surveys to CIPP patching and UV lining, our team provides tailored solutions for critical infrastructure projects, ensuring both safety and long-term performance.
