While traditional felt-based liners continue to offer reliable solutions in today’s marketplace, fiberglass UV-cured liners can be a valued alternative.


After thoroughly cleaning the host pipe, installation crews pull the UV liner into place. A protective sliding film or glide foil can be used in significantly deteriorated lines to aid in the pull-in process and to further protect the liner. Both ends of the liner are then sealed with protective end caps and air pressure is introduced, allowing the liner to expand into place. Workers then run a UV light train through the line at a controlled, pre-configured speed of up to 6 feet per minute to cure the liner.


Cameras on the train allow for viewing of the alignment and fit—both before and during the cure process. This computer-monitored process collects and stores data relevant to temperature, pressure and rate of conveyance to ensure proper curing of the installed liner. When complete, the laterals can be reinstated using a remote-controlled cutting unit or via man entry in larger diameter pipelines.
