The cured-in-place pipe (CIPP) technique is a trenchless rehabilitation method that is used for repairing pipelines. CIPP is a seamless, joint less pipe that is present within another pipe that has the capability to naturalize pipes that have diameters ranging between 0.1 to 2.8 meters. It is the most widely used trenchless rehabilitation method. CIPP is used for application in water, gas, and sewer pipes amongst others. There is a little to no digging involved in this trenchless CIPP process. During this method of rehabilitation, the damaged pipeline is infused with a resin material that coats the walls on the interior. This results in creation of a new pipeline that exists within the existing pipelines without the need to physically expose it by physical processes such as digging. Unlike conventional pipe repair methods, CIPP is completed within a short span of a few short hours while not having the need to stop the usage of the pipeline for weeks for repair.
