Cured-In-Place-Pipe (CIPP) is a trenchless method to repair existing pipelines of all sizes and shapes. This less invasive repair process is used to rehabilitate sewer, water, gas and chemical pipelines.
Using a resin-impregnated felt liner; it is then inverted into the problem pipe using air or water inversion through an access point. Using air or water pressure, the resin-impregnated liner is pushed through the pipeline and pressed against the walls of the problem pipe. Liners can then cure ambient or use hot water or steam to cure. Depending on curing methods, this process can take anywhere from 40 minutes to 4 hours. After the curing process, the liner forms to the pipe, making it a tight-fight, joint less, water and corrosion proof replacement pipe. The previous pipe serves as a protective barrier for the replacement pipe. Thus, a pipe with in a pipe! During this trenchless process, little to no digging is required – making this method of repair less disruptive and more cost-effective than the traditional "Dig and Replace" repair methods.
