Rehabilitation of watermains

Structural lining technology for the trenchless rehabilitation of watermains extends the useful life of the network by installing a liner impregnated with thermosetting resin. This technique helps minimize costs and traffic impacts compared to a traditional replacement method. More specifically, it makes it possible to increase the flow of the network, to restore its structural capacity in addition to resisting corrosion.
