Pipeline rehabilitation is the process of repairing or restoring existing pipelines to extend their service life or improve their hydraulic performance, preventing significant damage and service outages that would otherwise lead to costly repairs.
Request a quoteWe use tried and trusted techniques and technologies to address issues such as leaks, corrosion, structural damage, or reduced flow capacity in pipelines. These techniques include in-pipe patching, and the use of pipeline robotics and CCTV systems to ensure the accuracy of all installations.
We use the most advanced pipeline robots on the market to complete all rehabilitation projects as efficiently, and cost-effectively, as possible.
We use pipeline robots to cut, grind and shape pipelines. Many repair methods require water to maintain flow during the process, which TDG can offer. We can remove intrusions and obstructions such as tree roots, connections, and other foreign materials. We can cut junctions post-patch installation or grind a chamfer on a displaced joint to assist with restoring a pipeline’s hydraulic function or remove a failed liner.
We’ve taken our pipeline robotics services to another level. Our high-pressure water (HPW) pipeline robot can handle water pressures up to 43,500psi. It can perform precise cutting and remove stubborn blockages that traditional pipeline robots may find challenging, including heavy root mass, fats and even high-strength concrete.
We can install engineer-approved structural cured-in-place-pipe (CIPP) liners for pipelines ranging from 150mm to 1050mm in diameter to repair defects such as cracked, chipped and broken pipes, leaky lifting lugs and displaced joints. Our trenchless underground repair method, which utilizes a curing process involving heat or ultraviolet light to solidify the resin-soaked liner, will extend the life of an asset and remove the need for costly excavation and replacement.
With access to the latest technologies in equipment, jobs that would have previously taken days can now be completed in a fraction of the time and cost, with less disruption to your operations and the environment.
Our innovative solutions ensure that we address complex challenges effectively, particularly in sectors such as infrastructure maintenance.
TDG is second to none for expert drainage rehabilitation. Utilising modern innovative trenchless technology, TDG is an industry specialist in the installation of cured-in-place fiberglass point repair drainage patches. Compressed air is used to expand the resin-soaked liner during the CIPP process, ensuring a precise fit within the damaged pipeline. Other advanced drainage rehab products include large-diameter pipe seals and quality materials for sectional pipe relining. Technologies such as CIPP and pipe bursting allow for the insertion of new pipes, effectively replacing older infrastructure without extensive excavation. TDG has developed and provided holistic solution packages to fully rehabilitate both stormwater and sewer network assets.
TDG’s multi-functional Pipe Rehabilitation vehicles require a small operational footprint and are complimented with mainline CCTV pipe camera systems and powerful, remotely operated Robotic Milling units. Capable of removing all types of obstructions from pipes including concrete, tree roots, intruding connections and steel objects such as steel reinforcement and screw piles. All vehicles are equipped standard with a wide range of patch packers that provide the asset manager with a cost-effective option to repair drainage defects on the spot at a fraction of the cost of traditional methods. Addressing these issues promptly is crucial to prevent significant damage to the pipeline infrastructure.
High Pressure Water Blasting and Cured in Place Pipe
Our high-pressure water jet cutting robot has a huge cutting power of 43,500psi to allow for precise, controlled and quick cutting of concrete, grout, tree roots, scaling, solidified fat, failed liner, calcium and mineral deposits. This robotic unit differentiates from the traditional milling robot units in that it utilises powerful hydro-powered motors. This multifunctional unit is equipped with CCTV to monitor and control the works externally from the pipe. Grinding and milling attachments can still be utilised with the same unit for reinstating service connections and cutting protruding obstructions. The robot is self-propelled via cable, meaning it is safer to operate and only one access chamber is required to be opened to utilise it.
TDG provide a complete onsite solution to perform even the most challenging pipeline repair.
Our experienced patch crews are highly trained and certified delivering cost saving methods to restore ageing drainage assets back to full serviceability.
