Lining with continuous pipes
This lining method uses flexible pipes that are joined to form a strand on site.
Lining with discrete pipes
This method is based on factory-made pipe modules which are inserted one by one into the pipeline to be rehabilitated.
Partial rehabilitation by means of inserted rings is a purely mechanical rehabilitation metho.
Replacement and renewal methods
Pipe bursting technologies are used in the rehabilitation of pressure and gravity lines.
This method uses the same machines and procedures as the pipe bursting method and serves to replace pipelines made of ductile materials.
