This method is minimally invasive and can extend the life of existing pipes by several decades.
How Pipe Relining Is Performed
- Inspection and Cleaning: The process begins with a thorough inspection of the damaged pipe using a specialized camera to assess the extent of the damage. The pipe is then cleaned using high-pressure water jets or mechanical cleaning tools to remove any debris, roots, or buildup.
- Measuring and Cutting the Liner: A liner made of felt or fiberglass is cut to the appropriate length to fit the section of the pipe being repaired. This liner is then saturated with a resin mixture.
- Inserting the Liner: The saturated liner is inserted into the damaged pipe using an inversion or pull-in-place method. In the inversion method, the liner is turned inside out as it is pushed through the pipe using air or water pressure. In the pull-in-place method, the liner is pulled through the pipe using a cable.
- Inflating the Liner: Once in place, the liner is inflated using air or water pressure, pressing it against the inner walls of the existing pipe. This ensures that the resin bonds with the pipe surface.
- Curing the Resin: The resin is then cured, or hardened, using hot water, steam, or UV light, depending on the type of resin used. This creates a solid, seamless new pipe within the old pipe.
- Final Inspection: After curing, the newly lined pipe is inspected again to ensure the repair has been successful and that the pipe is free of any defects.
Benefits and Limitations
Benefits:
- Minimal Disruption: Pipe relining requires little to no digging, preserving landscaping and reducing the disruption to property.
- Durable Solution: The new inner lining is highly durable, resistant to corrosion, and can last for decades.
