The Trenchless Pipe Curing Process

The curing phase is the final and critical part of trenchless pipe lining in Arlington, VA. This procedure creates a new, durable inner pipe layer that fixes minor damage. There are different ways to finish it, with varying degrees of speed and difficulty, all with reliable durability.

Curing The Pipe Lining Layer And How Long It Takes

The final phase of pipe lining goes like this: after inserting the flexible resin-saturated liner into the pipe, the curing process hardens it in place. It forms a strong, seamless new pipe interior. This makes the procedure a key part of the process. 

The trenchless pipe lining curing phase varies depending on the method used: hot water, steam, or ultraviolet (UV) light. Plumbing technicians select the best approach based on pipe size, length, and environmental conditions. They use the best method applicable to the pipe conditions and surroundings.

Steam and hot water methods are often chosen for residential jobs. They take 2 to 4 hours to cure and set. UV curing is much faster, taking only 10 to 15 minutes. It’s used in larger commercial systems and homes where speed and precision are priorities. 

Ambient curing lets it set without any curing methods but dry air, but takes up to 24 hours. UV curing is the fastest, often finishing in less than 20 minutes, depending on pipe length and diameter.

Professional pipe lining companies monitor the curing process, using heat sensors and pressure gauges. These tools make sure it bonds the resin inside the liner cures uniformly in the host pipe. 

Materials Used In The Curing Process

CIPP lining or cured-in-place pipe uses resin as the core material. Other materials are epoxy, vinyl ester, or polyester resins. They harden into a rigid, seamless pipe that is corrosion and root-intrusion-resistant. Best of all, it restores pipes to full functionality with very minimal disruption.

Once sewer pipe lining is fully cured, professionals conduct post-lining inspections and testing. They last up to 50 years.
