Trenchless Sewer Line Replacement in Duluth, MN
When a sewer line is collapsed, severely deteriorated, or otherwise unsuitable for lining, trenchless pipe bursting is often the preferred solution.
The project begins with locating the sewer connection at the city main and excavating an access point. Inside the home, access is created where the sewer exits the foundation.
A hydraulic bursting unit is installed and a cable is run through the existing pipe. A specialized bursting head is attached to the cable along with a new HDPE sewer pipe that has been fusion-welded into one continuous section.
As the bursting unit pulls the assembly through the existing pipe, the bursting head fractures the old pipe outward while simultaneously installing the new HDPE sewer line in its place. The new pipe is then connected to the house and the city sewer system.
After installation, the area is backfilled, surfaces are restored, a new cleanout is installed, and a final camera inspection is completed. This process allows for complete sewer replacement while greatly reducing the amount of excavation required.
