Initial Video Inspection

Trenchless pipe lining in Boston, MA, starts with a video inspection. This is done using a small camera attached to the end of a long cord. The cord is inserted in the drain pipes or sewer line and takes real-time images of the internal section of the pipe. This allows us to determine the cause, the location, and the extent of the problem.

Pipe Cleaning

After the video inspection, the drain pipes are cleaned via hydro jetting. Having clean pipes is necessary to ensure the success of the repair.

Assembling the Liner

The next step in CIPP pipe lining involves assembling the calibration tube and structural liner. The calibration tube inflates the liner during cure time, and the structural liner becomes the new pipe's structure.

Mixing Epoxy and Saturating the Liner

The 2-part Epoxy is mixed and added to the liner. This process ensures that all of the felt fibers in the liner are saturated with epoxy.

Loading Liner into Inversion Tank

The saturated epoxy liner is loaded into the inversion tank, which is used to blow the liner into the pipe. The liner is fed through the inversion head and cuffed over the opening to initiate the inversion process. The inversion tank is filled with compressed air, which forces the liner out through the inversion head.

Reinstating Branch Openings

This is done using robotic reinstatement equipment. After the liner has cured, the branch openings are robotically re-opened since they are lined over during the sewer pipe lining process.
