The Perma-Lateral™ inversion unit does all the work. The installer calibrates the correct inversion pressure while the liner inverts itself through the existing host pipe and the Certified Installer controls the speed to ensure proper installation. Once the liner is inverted and holding pressure, the Installer attaches a special cap to hold pressure during the curing time. The Perma-Lateral™ inversion unit is released and used for the next installation. The liner holding pressure is maintained using a portable air tank.
The Perma-Lateral™ System is designed for 2" – 8" pipe diameters. The system can be installed through clean-outs or open end pipes. Only one access point is required. The liner can be ambient cured in 3 hours or steam cured in as little as 20 minutes. 2" to 4" diameter pipes can be rehabilitated up to 120FT+ in length, while 5" to 8" diameter pipes can be rehabilitated up to 600FT + in length. This is best selling small diameter pipeline rehabilitation system in North America!
