Nu Drain

logo_NuDrain

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. Our structural lining technology is best suited for pipe 2 inches to 12 inches in diameter with specialty applications available for larger pipe systems.

A crucial transition has been the adoption of “inside” underground lining applications for repairs to “outside” pipes where, in the past, those repairs were managed as external trenchless repairs requiring external solutions. CIPP restoration is a non-invasive procedure that uses epoxy inside a liner to create a new pipe inside deteriorated host piping systems and can span missing sections of pipe. 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.

Benefits

  • Prevents Root Intrusion and Stops Leaks
  • Increases Flow
  • No Digging or Destruction
  • Offers the Structural Strength of New Pipes
  • Alternative to Sewer Drain Replacement

Small Diameter Pipe Lining

NuDrain1Nu Flow’s Small Diameter Reline System can reline complete inside-infrastructure systems. Technicians using our patented tools can reinstate lined laterals. Branch lines can then be lined to the stack quickly and easily.

Lateral Lining

Nu Flow’s Lateral Lining system is sued to remotely repair full sections of damaged pipe or even sections anywhere in the lateral. Our lateral lining products allow us to remotely fix damaged pipe anywhere in the line. All of our products can be installed via the clean out.

Change in Diameter Pipe Lining

NuDrain2Pipes that change in diameter are never a problem for Nu Flow. Our transition liners allow to line pipes ranging in various sizes from 3”-4,5,6,8”, 4-5,6,8”, 5-6,8” and 6-8”.

Our patented expandable material gives the technician the ability to change diameter sizes anywhere in the line.

Our change of diameter tube gives you a full strength liner in both sizes without compromising the integrity of the pipe.

Environmental Benefits

CIPP is inherently environmentally friendly. An enhanced wet-out process helps us reduce waste during installation. Less equipment on the job site means less energy usage and less emission. 

Epoxy pipe lining is an eco-friendly solution that creates no waste for landfills or for recycling and generates no carbon emissions during manufacturing. Lining prevents heavy metals from leaching into drinking water and stops leaks and breaks in sanitary lines that pollute watersheds and seep pollution into groundwater. Nu Flow’s lining system leaves the smallest possible job site footprint and the shortest installation cycle of any small-diameter lining system in the industry. Our process is less disruptive, better for the environment and a better value for customers. 

The Problems

NuDrain_problemAging Sewer Lines
Most facilities/structures built prior to the early 1970s had sewer lines composed of primarily cast iron and clay. The primary problem seen in these lines is cracking and the bottom of the pipe rusting out. Common problems seen in clay pipes are root intrusion at the joints and cracks. 

Root Intrusion
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.

Calcification in Sewer Lines
Over time, calcium deposits from water form a crusted coating called ‘calcification’ which clogs up household pipes and drain lines, especially when hard water is in use. Once pipes are lined with epoxy, calcification can no longer occur because the deposits cannot adhere to the interior walls of the new epoxy barrier pipe. 

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. 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.

Millions of linear feet of drain and lines have been saved using the pull-in-place process. We realize every building and project is unique and Nu Flow installers have the experience and technical knowledge to meet your specific needs, regardless of the depth of the pipe or corrosive nature of the environment.
