100% inversion method – which means 100% of the resin seals all joints and cracks in the old pipe. The inversion liner materials consist of two layers of flexible needled felt and one layer of our scrim reinforcement and a 2-part formulated epoxy resin. The outside of the tube is coated with a 2 mil thick Polyvinyl Chloride finish.

The impregnated liner tube is inverted using the proven Perma-Lateral air inversion unit. This system is a true inversion technique using compressed air. The resin-impregnated liner is inverted (turned inside out) and pressed tightly against the host pipe until cured. The end result is a continuous liner with no joints and seamless from end to end. The cure time is about 4 hours. *Not a push-pull system. Only one hole is needed in most cases.

The ASTM F1216 specifications require a minimum life expectancy of 50 years.
