“No-dig” Drain Relining
Video Transcript
This video guide shows how our professional drainage engineers can repair faults in underground sewer and drainage systems without excavating. Drain repair companies like Aspect use drain relining patches to fix many sewer and drainage problems. Property owners might notice sewage smells, slow-running or completely blocked drains, or subsidence, all of which can be caused by damage to existing pipes.
Drain repairs should be done quickly to prevent more significant problems such as complete drain collapse, or underground subsidence. Drain and sewer pipe lining is a cost-effective repair option.
We demonstrate how drainage issues are precisely located and the extent of the damage is assessed using a CCTV camera drain survey. The ‘no-dig’ drain repair method, involving pipe relining from inside the drainage pipe, can effectively repair misaligned joints, cracks, holes, and even partially collapsed drains. This method ensures minimal disruption and can be completed within a few hours, from preparation to installation and curing inside the drain.
Equipment used:
- CCTV drain survey camera
- High-pressure water jetter
- Patch liner and resin
- Inflatable packer
- Pump and regulator
Steps covered:
- CCTV drain camera survey identifies faults in damaged drains
- High-pressure water jetting used to clear loose debris and prepare the pipe for repair
- Drain lining prepared with epoxy resin and fixed to an inflatable packer
- Packer is inserted inside the drain and inflated before being left to cure
- Packer is removed and the liner checked with a CCTV survey
The process of repairing drains and sewers is not only highly effective but also extremely reliable. When patch liners are installed correctly, they provide a permanent repair solution to damaged pipes. Our drainage engineers install them regularly, and we’ve never encountered a failure. In fact, some manufacturers claim their drain relining products will last for over 50 years if fitted correctly, further underscoring their durability and reliability.
