Tri-Star Contractors, Inc. is a certified Perma Liner CIPP installer placing liners in failing pipes from sanitary sewer to storm drainage, and ranging in size from 2″ to 96″.
Cured-In-Place Pipe, commonly referred to as CIPP, is a type of trenchless (no-dig) restoration process for damaged pipelines. It involves the use of a textile liner tube and liquid resin. Once in place, the combination of materials cures, providing a tight fit against the existing pipe.
This method of pipe restoration has been used for restoring wastewater pipes since 1971. Now it’s used all around the world, providing an economic alternative to the traditional, open-cut techniques for replacement.
Considered non-disruptive, this type of trenchless technology involves the inversion of a felt tube, saturated with a catalyst and thermosetting resin. The tube is then installed into the damaged pipe with water or air pressure. After the liner has made it through the current conduit, it is then heated using steam or water to create a tight fit and essentially create a “pipe within a pipe.” Pipes with diameters between 3 inch and 98 inch can be rehabilitated in as little as a single day in many cases.
In addition to full rehabilitation of pipelines with CIPP liners, Tri-Star also can repair a damaged line with a CIPP point repair. When the pipeline is in good condition but there is a puncture, crack, misaligned joint, or other failure, it may not be necessary to line the entire pipe. In this case, the failure is identified through video inspection of the pipe and marked for repair. A CIPP point repair is built to the necessary length to repair the damage and then installed into the pipe with robotics for positioning and cured into place.
The point repair is one of the most economical methods to repair a pipe with minimal interruption.
