Cured in place pipe lining (CIPP Inversion)

What is Cured-in-Place-Pipe (CIPP) lining?

Cured in Place Pipe lining is a trench less underground solution we offer to repair pipes that already exist underground without the need for digging a trench to reach the pipe. CIPP lining uses a textile liner tube along with a liquid resin epoxy to create a new pipe in place as the name suggests.  After the wet-out stage air pressure is used to invert the liner into the pipe. Once the inversion is complete a calibration tube goes inside the liner. There are several means of curing such as hot water or steam which activates the resin so that it will harden into a fitted, brand new pipe.

How long does CIPP take to cure?

Often CIPP liners usually takes about 12 to 24 hours for the resin to cure -however we use cutting edge technology that can cure in minutes and be completely cured and ready in 4 hours – at which point our Sewer technicians will use a camera to inspect the pipe making sure the lining is cured and that there aren’t any issues.

What material is used for cured in place pipe lining?

The liner is a fabric often non-woven polyester made to fit the pipe that is being repaired (host pipe). A polymer resin is injected into the liner.

How long does cured in place pipe lining last?

Just about as long as a full pipe replacement which is usually about 50 years.

How is cured in place pipe lining more eco friendly?
The epoxy resin is non-toxic and lasts a really long time. Not having to excavate and tear up landscaping is a big plus -sometimes requiring large machinery. Epoxy and liners also do not create carbon emissions. Also by eliminating the need to remove and dispose of old pipes creates less wastes making it yet one more environmentally friendly.

  • more cost effective than digging trenches
  • safer than excavation which can be hazardous for workers as well as anyone else or animals that may be in the neighborhood.
  • cipp is more environmentally friendly
