A resin-saturated felt tube made of polyester, fiberglass cloth or a number of other materials suitable for resin impregnation, is inverted or pulled into a damaged pipe. It is usually done from the upstream access point (manhole or excavation). It is possible to invert the liner upstream (e.g. from the downstream access point) but this carries greater risk. It is possible to install a liner from the downstream access point, upstream to a blind end however this carries the highest risk of all the CIPP installation methods. Little to no digging is involved in this trenchless process, making for a potentially more cost-effective and less disruptive method than traditional “dig and replace” pipe repair methods.
These images (above) of a pipe cutaway tell the story of what cured-in-place pipelining means. They illustrate a failing pipeline with root intrusion, corrosion or even breakage. The lower pipe illustration shows the same pipeline with a rehabilitated relined and sealed new pipe liner. This is the core of our business and could mean the difference between costly excavation and rebuilding of infrastructure versus a simple day of zero-dig pipe repair solutions. Our patented cured-in-place pipe repair systems provide you with a solution to failing underground sewer and pipelines. Our extensive line of trenchless pipe repair systems can rehabilitate pipes ranging from 2″ – 60″ in diameter. In addition to our underground pipe repair solutions, we also offer a wide array of vertical pipe repair solutions for high-rises, simple residential applications or industrial and factory facilities. If you have a failing pipeline please reach out to us and chat with one of our highly skilled relining experts. That call could save you thousands of dollars on your broken pipe repair project.
