How it Works

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). 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. This could mean the difference between costly excavation and rebuilding of infrastructure versus a simple day of No-Excavation pipe repair solution.

Old, failing sewer pipes can be rehabilitated without excavation

The images of the pipe cutaway shows exactly what cured-in-place pipelining means. They illustrate a failing pipeline with root intrusion and corrosion. The pipe on the left shows the same pipeline with a rehabilitated relined and sealed new pipe liner.
