The following are the crucial steps involved in drain repair:
- Inspection
The process begins with a sophisticated diagnostic assessment using CCTV technology. This involves employing a camera system in the drainage pipes to capture real-time visual data, allowing for an accurate internal evaluation. This inspection uncovers blockages, structural irregularities, and signs of wear or potential failure, giving a thorough assessment of the pipe’s condition.
- Diagnosis
Data from the CCTV inspection is meticulously analyzed to determine the specific types of drainage issues present. This stage utilizes analytical techniques to decode visual data, identifying problems like blockages, pipe deformations, or root infiltrations. The outcome of this analysis dictates the subsequent repair strategies, ensuring targeted and effective interventions.
- Cleaning
This stage is critical to preparing the pipes for repair. It utilizes hydro-jetting, employing powerful water streams to dislodge and clear away built-up debris, scale, and blockages. This method ensures that the pipe interior is thoroughly cleaned, optimizing conditions for effective repair and minimizing the risk of post-repair complications.
- Repair
Repair methods are chosen based on the diagnosis:
Pipe Relining: This technique involves inserting a resin-impregnated liner into the compromised pipe, which is then cured, effectively creating a new pipe within the old one. This method restores pipe integrity and is favoured for its minimal invasiveness.
Pipe Bursting: For extensively damaged pipes, this method replaces the damaged pipe by fracturing it and simultaneously pulling a new pipe into place through the created void.
Patch Repair: Patch repair refers to a method used for localized damage. It involves placing a resin-impregnated patch over the affected area, which is then cured to seal and reinforce the pipe.
- Testing
After repairs, the system undergoes thorough testing to guarantee its functionality. This includes pressure testing and leak detection, employing methods such as dye testing and further CCTV inspections to confirm the integrity of the repairs and the system’s readiness for regular operation.
- Finalization and Documentation
The repair process concludes with site restoration, returning any disturbed areas to their pre-repair condition. Detailed documentation is produced, cataloging the repair process, techniques, and warranties or guarantees. This is a vital record for maintenance teams and supports ongoing infrastructure management.
These stages illustrate an effective approach to drain repair, emphasizing precision, effective issue resolution, and long-term structural integrity maintenance, which is crucial for robust water management in various property settings.
