What is Cured in Place Pipe?

Cured in Place Pipe (or CIPP), as it is most often referred to, is a method for repairing underground pipes that are damaged or broken. The product is made up of a felt type lining that is impregnated with a specially formulated resin, which is then inverted into the damaged pipe or pulled into the pipe before it is inflated. At this point, the resin is cured using either hot water, steam, or UV light.

What is Cured in Place Pipe made from?

A variety of materials can go into the liners used in the CIPP process, including but not limited to Polypropylene and Polyester felts, knit fabrics, woven fiberglass, Polyurethane, Polyethylene, and PVC coatings for moisture barriers, and epoxy and styrene resins to hold the new pipe in place.

It is also worth noting that pipes with 2in diameter up to 10ft can all be repaired using this method.

What are the Advantages of Using Cured in Place Pipe?

The primary advantage of utilizing CIPP is that you do not have to dig up a damaged pipe to fix any leaking, broken, or corroded underground utilities. Another benefit to CIPP is that it appears to have a  much longer design life than the 50 years the product touts as a design life.

How Does Cured in Place Pipe Work?

The cured in place pipe installation process is most frequently utilized among utilities companies and municipalities to repair neighborhood or busy city streets. As long there is an access point (such as a manhole) at both ends, you can replace 300 feet of pipe at a time or more in some niche applications without having to dig up any pipe. Once a line is repaired with the CIPP method, that line can no longer be cabled or snaked with a machine; it must be cleaned by way of Hydro jetting (AKA high-pressure water blasting)

What Makes Presco’s CIPP Stand Out Amongst the Competition?

One area we excel in at Presco, our extrusion lines have in-line profile management and in-line camera inspection technologies that allow us to make a very consistent product that will maintain an even profile thickness and be able to be inspected for visual defects while the product is being made.  This leads to a very secure bond across the width of the web and a higher level of quality assurance. Also, because we are primarily a filmmaker, we can produce film that is the same compound that we use to coat the felt liners so that the adhesion at the seams is more robust and harmonious.
