A cured-in-place pipe (CIPP) liner provides an ingenious solution to repair a cracked, leaking, or broken sewer pipe without the need to dig a trench underground. The liner itself consists of a resin-soaked felt tube with an impenetrable exterior coating of polyurethane.
Installation begins by gently inserting the liner into the host pipe, then inverting the resin-soaked felt into the correct position. The inversion results in the polyurethane exterior becoming the interior, effectively creating a pipe-within-a-pipe. The curing ( heat or UV) process causes the resin-soaked felt to seal itself to the damaged pipe lining, creating a strong, highly durable inner tube. As a result, it effectively repairs the original without the need for digging or construction.
Leaking, aging, or malfunctioning sewer, storm water, and sanitary pipe systems have long-term repercussions for municipalities, the environment, and the public at large. However, the time, effort, hazard, and expense of performing traditional open-cut repair is often too cost-prohibitive to be a feasible option. CIPP liners provide a cost-effective, quick, and efficient alternative that has proved time and again to be an ideal choice for trenchless pipeline rehabilitation.
Utilizing our CIPP liners provides numerous benefits, including:
Greater Safety: CIPP lining installation doesn’t require the hazard of open-cut repairs and excavation, making the process much safer for everyone.
Cost-Effective: Open-cut pipe repair costs 20 to 40% more than using a cured-in-place pipe liner, making CIPP liners an affordable alternative.
High Durability: Traditional pipe repair often results in sewage leaking out via seams or cracks, which can also allow groundwater infiltration. CIPP liners are jointless, preventing those issues and extending the longevity of the host pipe for up to 100 years.
Excellent Versatility: Most damage to sewer or water pipes can be repaired through CIPP lining. It can fix cracks, breaks, deterioration, root intrusion, corrosion, fractures, and more, which is why it’s such a versatile repair option.
