Nu Flow is the industry leader when it comes to epoxy lining.

Nu Flow has patented its pull-in-place structural lining process along with its epoxy coating system. The easiest way to determine which process is used for a particular project or scope would be by breaking the piping systems into two categories, pressurized and non-pressurized piping systems.

Pressurized Water Systems

Epoxy pipe lining was brought to North America in 1987 by American Pipe Lining. The company began employing its epoxy lining technology as a sole source contractor to the United States Navy aboard its carrier vessels. American Pipe Lining’s success with the U.S. Navy brought immediate attention to land-based clients that required similar services in their buildings and underground piping installations. Following EPA approval of its coating in 1988, American Pipe Lining began providing in-place pipe restoration services to clients that faced aging potable water systems and poor water quality, including a variety of low and high-rise housing developments, schools, industries and water utilities.

In 2006, APL granted an exclusive license to Nu Flow to utilize all technologies and patent right, making Nu Flow the only pipe and drain Rehabilitation Company which both manufactures and installs combined technologies for pressurized water systems, as well as trenchless repair on non-pressurized systems. Nu Flow acquired APL in 2007, solidifying Nu Flow’s position as the industry leader in small diameter pipe lining.

In-place epoxy pipe lining is a process that restores corroded or eroded piping systems without the costly expense and disruption of pipe replacement.
  • Significant savings over repipe or pipe replacement
  • Increases life of piping
  • Very little disruption, if any
  • Preservation of building structure and surrounding landscape or hardscape
  • Little to no destruction to the property
  • Destruction of existing walls, ceilings, floors and underground structures
  • Patching and repair of the damaged structure
  • Inconvenience and disruption to building/facility occupants or residents
  • Safety concerns where asbestos insulation or other contaminants are present
  • The need to temporarily vacate occupants and dwelling tenants High monetary cost
  • Minerals leaching from pipes into drinking water

  • Mineral deposits that limit water flow

  • Corrosion of the pipes and discolored water

  • Pinhole leaks

  • Plugged fixtures and aerators

  • Joint Failures

  • Electrolysis

Pipe lining provides an efficient, effective alternative with many benefits, which include:

  • Significant savings over repipe or pipe replacement
  • Increases life of piping
  • Very little disruption, if any
  • Preservation of building structure and surrounding landscape or hardscape
  • Little to no destruction to the property

Non-Pressurized Pipe Systems

In the early 1970’s, Eric Wood developed the first cured-in-place pipe technology (CIPP) in England. He then named the CIPP process insitu form, meaning “form in place” in Latin. Wood received patent no. 4009063 for this technology on February 22, 1977 and was commercialized by Insituform Technologies on February 22, 1994 when CIPP entered the public domain.

During this time the CIPP market’s main focus was on large diameter pipes from 4” to 118” and geared towards the municipal sector. This process was called “inversion” and required large equipment and in most cases, would require digging pits for it to effectively work.

During the 1990’s in Toronto, Canada a new technology would emerge in the CIPP market. Cameron Manners, the founder of Nu Flow and inventor of the technology, saw a void in the CIPP market and developed a pull-in-place method that focus on the small diameter market of 2” to 12” pipes.

Nu Flow has received multiple patents for its pull-in-place structural lining process and methods and since its inception has licensed the technology to nearly 400 companies internationally with installation on 6 continents.

Nu Flow’s pull-in-place method has revolutionized the CIPP market by bringing the structural liner inside the building. Nu Flow has been the leader in inside infrastructure rehabilitation. The pull-in-place method requires the use of existing access points along with the flexibility in the product and how to apply it. The process allows for full control by pulling or pushing the liner into place, a perfect match for large projects within the building’s infrastructure.

Pull in place pipe lining is an effective process that restores corroded or eroded drain, waste and vent piping systems without the costly expense and destruction required to replace pipes.
  • Significant savings over repipe or pipe replacement
  • Increases life of piping
  • Very little disruption, if any
  • Preservation of building structure and surrounding landscape or hardscape
  • Little to no destruction to the property
  • Clogged or backed up
  • Loss of structure and pipe is caving
  • Tree root intrusion of the pipe
Pipe replacement in aging facilities, the traditional alternative to pipe lining, comes with a host of concerns and issues that must be dealt with, some of which can render such work highly prohibitive.

These include:

  • Destruction of existing walls, ceilings, floors and underground structures
  • Patching and repair of the damaged structure
  • Inconvenience and disruption to building/facility occupants or residents
  • Safety concerns where asbestos insulation or other contaminants are present
  • The need to temporarily vacate occupants and dwelling tenants
  • High monetary cost
