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.
