Pipe Rehabilitation & Robotics

TDC offer trenchless pipeline repair by way of Pipeline Robotics and In Pipe Patching.

Whether it is a large pipe displacement, cracks and fractures, concrete slurry ingress or an intruding connection there is no need for unnecessary expensive and messy excavation to repair the pipe. TDC can carry out the repairs from the pipe internally.

Trenchless pipeline rehabilitation provides our clientele with an innovative and cost-effective option for repair of pipe defects at a fraction of the cost of excavation and open cut replacement.

Our experienced operators utilise our multi-functional trucks cohesively to provide a turn-key solution for challenging pipeline repairs.

Pipe obstructions (such as roots, intruding connections, concrete, displaced joints, etc) increase the risk of debris becoming lodged, preventing access and affecting pipe flow.

Using our hi-torque robotic system, we can cut and grind most size pipes, easily removing unwanted material and intrusions restoring total hydraulic functionality.

Our pipeline robots can perform works internally of pipelines in diameters ranging from DN225 to DN800. The robots have a cable length and reach of 120m and are propelled by powerful electric motors. The Prokasro Electric System is as powerful if not more than the latest Hydraulic Systems and at least 3 times more powerful than any pneumatic system.

Our localised pipe patching repairs are an efficient and cost-effective solution for isolated defects, including cracked, chipped and broken pipe sections, leaky lifting lugs and displaced joints.

With a broad range of repair equipment, we are able to install repairs in pipes from 150mm up to 1050mm in diameter. Patches can be installed in either 600mm or 1200mm lengths and provide a localised structural repair with minimal liner thickness (<5% of pipe diameter).

Man-entry hand repairs can also be carried out in larger pipes.

Our Pipe Rehabilitation Units are able to operate in remote locations with suitable equipment to access back yards and difficult locations.

Overall, patch repairs are completed all at a fraction of the cost of traditional methods, require less disruption and manpower and require less time to set.
