PRT - Liner End Seals
Quick-Lock liner end seals strengthen a CIPP liner at its most vulnerable points—the ends. Stronger and easier to install than other end caps, they have the same locking mechanism and gaskets as the rehab sleeves. They’re a must-have insurance policy for installed CIPP.

Before rehabilitation begins, a robotic cutter is used to mill a gap between the lateral and mainline. Then a robotic packer is winched into position, where it:
- Isolates and pressure-seals the lateral/mainline gap to the first joint of the lateral.
- Injects a fast-curing resin that bonds with milled pipe walls, fills gaps and re-establishes bedding support.
- Waits 20 minutes for a cure.
- Verifies the seal using onboard cameras.
- Is winched to the next lateral.
- Structurally addresses the primary cause of lateral failure: inadequate bedding.
- Permanently solves infiltration, root intrusion and ground cavity problems.
- Requires no line plugging.
- Prevents future sink holes.
- Fills the gap between liner and host pipe.
- Doesn’t interrupt traffic.
- Has a life expectancy of 60-80 years (oldest proven technology).
