How does Cured-in-Place Pipe (CIPP) work?

Over time, pipes deteriorate and need to be repaired to prevent leakage and contamination. Commonly called CIPP in the industry, Cured-In-Place Pipe is a trenchless technology used to rehabilitate a pipe, instead of replacing it. How exactly does it work?

First, a felt liner is injected with resin. Next, air or water is used to insert the liner into the deteriorating pipe. Finally, the resin is activated by ultraviolet (UV) light, steam or boiling water for curing. The curing hardens the resin and turns the liner into a structurally sound pipe within a pipe.

Not only is CIPP safe for relining pipes used for sewer and storm, drinking water and culverts, but it has other benefits including:

  • It’s trenchless – so no digging is required
  • It extends the life of the pipe for up to 50 years
  • It’s cost-effective

Michels designs and manufactures each liner to the exact specifications of the owner and manufacturer of the pipe in diameters from 6 to 100 inches. Our regional wet-out facilities ensure our ability to quickly and efficiently serve customers from coast to coast.
