N-Liner™ is a cured-in-place pipe system used to rehabilitate deteriorated pipeline. Commonly referred to as CIPP.  It is comprised of a non-woven, needled polyester felt tube which is saturated with a thermosetting resin and when  cured becomes a new pipe within the old pipe.

Installation begins with the cleaning and televising of the pipeline and once completed the inversion process can begin. Inverting the liner into the old pipe starts with inserting the liner into a standpipe that is securely suspended directly above an existing manhole. The liner is turned inside out and attached to the bottom of the standpipe.  Water or air is added to the standpipe to provide the necessary head pressure to invert the liner through the old pipe.

Once N-Liner™ is in place, thermocouples are placed at both ends to monitor the temperature of the curing process. The temperature of the water or air inside the liner is then slowly elevated and circulated to transfer the appropriate amount of heat to cure the resin. 

After the liner has cured, lateral lines are reopened with a remote-controlled, robotic cutter. Applications 6" – 108”.
