What Is Cured-In-Place-Pipe (CIPP)?
Water Main CIPP CIPP is a means of rehabilitating an existing water main using a woven polyester tube that is impregnated with liquid epoxy. The epoxy is hardened through the application of heat. Once the epoxy has cured it becomes a structural component which lines the internal dimensions of an existing water main, taking the form of the main’s interior and shape. Waste Water Main CIPP CIPP is a means of rehabilitating an existing waste water main using a felt tube impregnated with liquid resin. The resin is hardened through the application of heat. Once the resin has cured it becomes a structural component which lines the internal dimensions of an existing waste water main, taking the form of the main’s interior and shape. CIPP Material Water Main Application The liner is made of two concentric tubular plain sleeves. Its inner sleeve is coated with polyurethane. Both sleeves consist of woven polyester. Waste Water Main Application The liner typically consists of multiple layers of fe
