South Boston trenchless sewer lining project
We cleaned corroded, leaking 4-inch and 6-inch cast iron sewer lines in a South Boston building and lined them with cured-in-place pipe (CIPP) from inside.
Our camera found scale and cracking along the building's cast iron runs.
Our camera inspection showed scale and cracking along the cast iron runs serving the property, with leak risk at deteriorated sections.
The footage covered both the 4-inch and 6-inch lines and confirmed that trenchless lining could renew them without excavating the concrete floor along their route.
We jetted the cast iron clean and staged our inversion drum indoors.
Our hydro jetting removed rust, grease and debris before we sized the liner and prepared the resin.
We staged an inversion drum indoors and prepared the resin-saturated liner for installation under air pressure.
Our photographs show the camera and lining equipment from this job.
We inverted the liner under air pressure and cured it inside the cast iron.
We inverted a resin-saturated liner under air pressure and cured it to create a jointless pipe wall inside the existing cast iron sewer.
We answer two questions about this South Boston job.
Why does an interior installation still need access?
Our camera, cleaning tools and inversion drum need a connection to your sewer. Trenchless lining reduces the need to excavate along its full route, and we plan the access arrangement around your building.
What pipe sizes were involved?
This property's sewer included both 4-inch and 6-inch cast iron sections, and we lined both.
We renewed the corroded sections without a full-length floor excavation.
We renewed the corroded sections with a cured liner installed from interior access, so we avoided a full-length excavation of the concrete floor along the cast iron runs serving the building.
If your cast iron sewer runs beneath a concrete floor, our camera recording shows whether we can line it from inside.
