The fiberglass liner process for sewer line repair, also known as cured-in-place pipe (CIPP) lining, is a trench-less technology used to restore the integrity of cracked lines without the need for extensive excavation. Here’s a detailed description of the procedure:
1. Inspection
Video Camera Inspection: A camera is introduced into the sewer line to assess the extent and nature of the damage. This allows the us to determine if the cracked areas are suitable for repairing with the fiberglass liner.
2. Cleaning
Pipe Cleaning: The affected sewer line is thoroughly cleaned using high-pressure water jets or mechanical cleaning tools. This step removes debris, tree roots, and other obstructions to facilitate proper adhesion of the fiberglass liner.
3. Preparation
Measurement: The plumber measures the length of the damaged section of the pipe to determine how much liner material is required.
Liner Saturation: A fiberglass liner, typically made of a flexible tube, is impregnated with a resin mixture. This resin will harden and create a new pipe within the existing one.
4. Installation
Insertion of the Liner: The saturated fiberglass liner is carefully fed into the sewer line using a winch or air pressure. It needs to cover the damaged area completely.
Inflation: Once in place, the liner is inflated against the walls of the existing pipe. This can be done using air or water pressure, allowing the resin to bond with the interior surface of the original pipe.
5. Curing
Setting the Resin: The liner remains inflated for a specified period to allow the resin to cure and harden. Curing can be done using hot water or ultraviolet (UV) light, depending on the materials used. This process typically takes a few hours.
6. Final Inspection
Post-Installation Inspection: After curing, a follow-up video camera inspection is conducted to ensure that the liner is properly installed and that there are no remaining issues in the sewer line. This inspection confirms the integrity of the repair.
7. Restoration
Restoring Access Points: Any access points or cleanouts that were used during the process are resealed or restored to their original condition.
Cleanup: The area around the access point is cleaned and left tidy, ensuring minimal disruption to the property.
Advantages of Fiber Glass Liner Repair:
Minimal Disruption: The trench-less method significantly reduces the need for digging, preserving landscaping and existing structures.
Durability: The fiberglass liner provides a new, corrosion-resistant surface that can last for decades.
Cost-Effectiveness: While the initial investment may be higher than traditional repairs, the long-term savings on excavation and restoration can make it more economical.
In summary, the fiberglass liner procedure for sewer line repair is an efficient and effective method that enhances the lifespan of existing pipes while minimizing disruption to the property.
