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.
