As a specific application of CIPP, Nu Flow’s patented pull-in-place system is used in products like Nu Drain to offer the most advanced piping repair solution on the market.
With the PIP application, a felt liner is saturated with epoxy and pulled into place. Once in place, an internal rubber bladder is expanded with air pressure allowing the epoxy to adhere to the host pipe.
Pull-in-place applications allows you to line multiple 45° and 90° angles and provides the option to line specific sections of pipe without lining the entire length.
Nu Flow has dedicated years of research in order to develop industry-leading technologies that address piping system degradation that is rapidly occurring around the world today.
Our findings from over 7000 hours of research have led to the development of a comprehensive product portfolio of non-invasive, in-situ epoxy coatings, structural liners and piping repair kits capable of addressing any structural piping issue anywhere in the world.
The Cured-in-Place Pipe System (CIPP)
Nu Flow’s patented, cured-in-place pipe (CIPP) system creates a protective, structural pipe inside the existing host pipe system, without digging or destruction to buildings or landscape.
This epoxy pipe liner creates a seamless, jointless, pipe-within-a-pipe that is used to rehabilitate deteriorating sanitary drain and storm sewer lines, including mechanical systems, with minimal disruption.
Nu Flow’s liner enhances the structural strength of host pipe and acts as a stand-alone pipe within a pipe, meeting or exceeding ASTM D790, D638 and D543 Standards.
Our structural lining technology is best suited for small-diameter pipe, 3/4 inches to 12 inches in diameter. Nu Flow also offers specialty applications for larger pipe systems.
In the past, repairs to outside pipes were managed as external trenchless repairs requiring external solutions.
A crucial transition has been the adoption of “inside” underground lining applications for repairs to “outside” pipes.
CIPP restoration is a non-invasive procedure that uses epoxy inside a liner to create a new pipe inside deteriorated host piping systems. This lining is highly specific, and can be used to span missing sections of pipe.
Both strong and durable, epoxy pipe lining is a long-term solution for leaks and breaks, blockages, root intrusion, calcium build-up, water damage, mold, sewer backups and increases flow capacity.

What kind of problems does Nu Flow structural lining technologies address?
Aging Sewer Lines
Most facilities/structures built prior to the early 1970s have sewer lines composed of primarily cast iron and clay. These lines are subject to cracking and rusting out at the bottom, which leads to root intrusion at the joints and cracks.
Root intrusion into sewer pipe systems is reported to cause 50% of all sewer blockages. Interference of trees into sewer systems is likely to occur in older systems and in cracked pipes. Factors that contribute to damage include older pipes with joints, shallow pipes, small-dimension pipes and fast-growing tree species. Cost associated with caring for root intrusion in the past has been expensive and laborious and unfortunately, is rarely a long-term fix.
Solution: Nu Flow structural lining technologies protect against further intrusion in joints and cracks. Because of the nature of root intrusion, it is best to reinforce and protect pipes before major intrusions have taken place.
Calcification in Sewer Lines
Over time, sewer lines will calcify, as calcium deposits from the water build up over time and create a coating that clogs up household pipes and drain lines. This is especially true for buildings with hard water due to its high levels of calcium.
Solution: Nu Flow epoxy lining makes it impossible for calcium deposits to adhere to the interior walls of the new epoxy barrier pipe, preventing future calcification.
Ground Movement Affects Sewer Line Integrity
Major seismic activity can cause breaks in sewer lines, but more frequently, minor seismic activity causes cracking and structural damage at the joints.
Solution: The seamless, “jointless” nature of the PIP method means not only is the existing problem solved, but the new, seamless pipe will avert future problems as well.
