IRSI is the sole manufacturer of our patented Trenchless Mainline, Lateral, & Elbow Point Repair Systems in four different liner weight options and customized liner lengths and thicknesses.



The IRSI Mainline Point Repair System is a no-dig, ambient cure permanent solution to repair any size pipe with minimal interruption of service. The complete, user friendly point repair kit features a patented, easy to wrap, sewn fiberglass and felt liner that stays in place. It is available in 4 liner options with pre-measured epoxy formulated for summer or winter environments.


The IRSI Lateral Point Repair System features an ambient cure, two part, no shrink or creep, epoxy system along with liners that are sewn together with patented pop-open Velcro straps and melt-away strings to securely hold the liner in place on the carrier. The carrier can be pushed or pulled through a straight 3” or through a 4” or larger 90° cleanout to position it over the damage for a permanent, trenchless lateral repair.

The IRSI Elbow Point Repair System is a patented, flexible fleece and fiberglass liner technology. The flexible center of the liner creates a strong, smooth, unobstructed curve in up to a 90 degree bend. It seals joints, cracks, or even missing pieces of pipe. Our no-shrink epoxy system cures in as little as two hours.
