Trenchless Pipe Lining in Dorchester, Boston

Dorchester Trenchless Sewer Repair — Boston Pipelining Company

Boston Pipelining Company recently completed a trenchless rehabilitation in Dorchester, Boston. The homeowner had a failing clay sewer line running beneath a basement slab, causing backups and stress. Instead of breaking through the foundation, our crew used a trenchless sewer repair method to restore the pipe with no major excavation.

Detailed Video Inspection

As with every job, we began with a full sewer inspection using high-resolution camera equipment. This step revealed fractures, scaling, and root intrusion that had been restricting flow. With a clear understanding of the problem, we recommended a CIPP (cured-in-place pipe) solution for a long-term fix.

Line Preparation

The next step was cleaning the pipe using hydro jetting to remove years of buildup and corrosion. A clean host pipe is essential for bonding the liner. Once the pipe was ready, our team staged the SacTools inversion drum and prepared the resin-saturated liner for installation.

Liner Installation & Curing

We inverted the liner into the host pipe under air pressure, ensuring it conformed to every bend and joint. After curing, the old damaged pipe was now reinforced with a seamless, jointless liner. For added protection, our crew can also apply epoxy brush coatings for smaller diameter lines, extending service life even further.
