1. Prelining survey and milling of corporation valves. Existing corporation valves often protrude into the pipe and can be disruptive to the trenchless rehabilitation process. The protruding ends of the corporation valves are robotically removed.





2. Lining. The deteriorated host pipe is renewed using one of Insituform Blue’s® non-disruptive rehabilitation process: Thermopipe®, PolyFlex™ or PolyFold®.








3. Locating service connections and cutting lining. A remote operator locates each service connection using eddy current technology, an innovative, electronic method of detection. Once the connection is located, a rotating milling head cuts through the liner.





4. Installation of seal. A water-tight, pressure-rated mechanical seal is achieved when a self-tapping T-Nut and gasket are installed in each corporation valve.
