After preparing and finalizing the main pipe lining, four crucial steps remain: polymerization, connection reconnection, leak testing, and identification of the rehabilitated sections. First, polymerization ensures the rigidity of the polyester sheath using a UV process, curing a resin with UV lamps. The connections are then reconnected by a robot equipped with a cutter and a camera, allowing for remote control. Leak tests ensure the absence of leaks in the rehabilitated network. Finally, the identification of the rehabilitated sections includes the attachment of information plates at each end inspection chamber. This method of network rehabilitation using lining is essential for maintaining the integrity of the infrastructure without the drawbacks of traditional methods.
