CIPP Leaves Diverse Attractions Undisturbed

Over the hole insertions at existing manhole sites eliminated the need for trenches.

The heat accelerates a chemical reaction that cures the resin from a liquid state to a molecularly crosslinked solid with excellent corrosion resistance and durability. The result is a new seamless liner. Robotic equipment cuts openings to reconnect laterals to the main pipe.

The recent sewer rehabilitation in Reno by PIPEnology totaled 25,285 feet of 8 to 72 inch diameter sanitary sewers. More than 40 percent of the work involved pipe that was 60 inches in diameter or more.

For this work, PIPEnology chose Vipel corrosion resistant resin from AOC, a global leader in resins for sewer infrastructure. “Because of the excellent teamwork involved, including prompt AOC service and delivery, we were able to get the CIPP phase of the work completed in less than five months,” Broyles stated.

Managed and operated by professionals with over a decade of experience and expertise, PIPEnology specializes in cured in place pipe (CIPP) rehabilitation of pipelines of all sizes and materials.

AOC is a leading global supplier of resins, gel coats, colorants, additives and synergistic systems for composites and cast polymers. Cured in place pipe systems and other sewer rehabilitation are priorities and areas of expertise for AOC.
