Cured-in-place materials seamlessly mold to the host pipe, restoring the structural integrity of the pipeline to prevent infiltration and exfiltration in circular, elliptical, rectangular, and transitional-diameter pipe sections. It eliminates joints, effectively preventing root intrusion and environmental corrosion. It can form a smoother surface than host pipe, which actually increases flow capacity. With a diameter range of 4 inches to 120 inches and the ability to span sections up 3,000 feet long, CIPP can be used for water, sewer, gas, and chemical pipelines. Because CIPP is installed using trenchless technology, it is particularly useful in historic, densely urban, or rough terrain areas where construction easements may be limited or unavailable.
