About iPlus Infusion®
iPlus Infusion® is Insituform's next generation, small diameter cured-in-place pipe (CIPP) solution. Enhancements to manufacturing and installation allow us to deliver higher value, better quality and less disruption.
iPlus Infusion® is a seamless, jointless, pipe-within-a-pipe that can be used to rehabilitate deteriorating sanitary and storm sewers without digging or disruption. The product consistently meets or exceeds the physical properties set forth in ASTM D1743.
iPlus Infusion® CIPP: Manufacturing and InstallationAll iPlus Infusion® tubes are produced at Insituform's own ISO 9001 certified manufacturing plant. A robust pull-in method is used to install the tube into the host pipe, reducing the stress on the tube. It can be installed in pipeline with diameters from 6 inches to 12 inches and in lengths up to 750 feet.
A low-pressure steam is used to cure the iPlus Infusion™ tube. The steam cure allows us to reduce our energy and water use and virtually eliminates the discharge of process water into the sewer system.

The iPlus Infusion® installation process has the smallest possible jobsite footprint and the shortest installation cycle of any of the Insituform CIPP processes.
iPlus Infusion® CIPP: Environmental BenefitsCIPP is inherently environmentally friendly, but we have raised the bar by applying green engineering concepts to the design of iPlus Infusion®. An enhanced wet out, or resin impregnation process, helps us reduce waste. Using steam instead of water to cure the resin significantly reduces energy use. Less equipment on the jobsite translates into less energy usage and less emissions.
Insituform set out to enhance its proven CIPP process to ensure quality, shorten the installation cycle, reduce waste and conserve energy. These efforts have resulted in a system that is less disruptive to citizens, better for the envirnoment and a better value for our customers. iPlus Infusion® addresses your top concerns.
Infiltration ReductionWater entering yout sewer system through cracks, holes and joint failures can significantly tax your treatment facilities, especially during wet weather. iPlus Infusion® can significantly reduce this infiltration and leakage from affecting your system.
Structural IntegrityiPlus infusion® restores structural integrity to your damaged sewer pipe. Proactively maintaining the integrity of your pipes can help you avoid the high costs and negative publicity associated with emergency repairs.
Increased Flow CapacityThe smooth, jointless interior of our iPlus Infusion™ CIPP improves flow capacity, despite the cross-sectional reduction. There are no joints or seams that separate over time.
