What is Rolldown Pipe Rehabilitation Overview about?
The Rolldown technique is an economical method for rehabilitating pipelines between 500-1200mm diameters over long distances. It involves inserting a standard PE pipe into the existing pipeline and using a machine to reduce its diameter by up to 10% for insertion. Once inside, the liner is expanded back to its original diameter through pressurization to tightly fit the host pipe wall. This results in a pipeline with new condition and quality while not loading the original pipe.
