Is your sewer line damaged beneath your driveway, yard, or even your home’s foundation? Traditional repair methods often involve major excavation, damaged landscaping, and high labor costs. Fortunately, modern trenchless sewer line repair technology provides a more efficient solution.
In this complete guide, Red Rock Trenchless answers, “How does CIPP lining work?” explaining why it’s best for long-term pipe rehabilitation.
What Is CIPP Lining?
Cured-in-place pipe (CIPP) lining is a trenchless repair method that rehabilitates your existing pipeline from the inside out. Instead of replacing the damaged line, a flexible liner saturated with epoxy resin is inserted into the existing pipeline. This liner is then cured in place, forming a new structural liner within the old line.
How Does CIPP Lining Work? A Complete Overview
Sewer line repairs are precise, engineered procedures that deliver durable results with minimal surface impact. Here’s a step-by-step overview that answers “How does CIPPP lining work?”
Inspection and Cleaning
The process begins with a video camera inspection to locate damage and assess the condition of the sewer. Then, hydro-jetting is used to remove obstructions, such as tree roots, debris, and buildup, ensuring the liner adheres properly to the walls.
Liner Preparation and Installation
A felt or fiberglass liner is saturated with liquid epoxy resin to ensure strong bonding. Using the inversion process, the liner is inserted into the damaged line, turning it inside out as it’s guided into position. This places the resin-coated side against the inner surface of the duct for maximum contact.
Curing the Liner
The liner is hardened or cured in place using one of the following methods, depending on the project’s requirements:
- UV light: Delivers quick and uniform curing, ideal for smaller or straight duct runs.
- Hot water or steam: Provides consistent heat throughout longer or complex line systems.
Once the resin cures, the liner forms a strong, seamless structure that fully restores the pipe’s functionality and integrity.
Final Inspection and Reinstatement
After curing, a second camera inspection ensures that the new duct is fully formed and defect-free. Any lateral connections from your home have been reopened, and the new line is now ready for use.
Why Trenchless Technology Is the Smarter Sewer Repair Option
Opting for CIPP lining instead of traditional digging offers numerous long-term advantages, especially for lines beneath structures or landscaping:
- CIPP lining requires no excavation and preserves your lawn, driveway, and foundation.
- Most projects are completed within one to two days.
- It reduces overall costs by eliminating trenching and surface restoration.
- The structural liner lasts over 50 years and resists corrosion and root intrusion.
- It works with clay, cast iron, PVC, and concrete pipes.
- The smooth interior improves flow and prevents future buildup.
