Large-Diameter Pipe Lining
Interceptors, trunk sewers and big storm lines can be rehabilitated in place, avoiding the enormous cost and disruption of open-cut replacement.
The details, in plain English.
Large pipes carry large consequences. Replacing a trunk sewer or a storm line means deep trenches, traffic detours and months of work. Lining restores the pipe in place, often with a structural liner designed to carry soil and traffic loads.
Large-diameter jobs are engineered: we review the existing pipe, flows, depth and loads, then specify the liner, cure method and bypass plan. Safe entry, inspection and documentation are part of every project.

- Trunk sewers and interceptors

Questions, answered
How big a pipe can be lined?
CIPP is used in very large pipes. The limits depend on the design, access and site, and are set during assessment.
Do you need to shut down flow?
Flow is controlled or bypassed during installation and cure.
How do I get a price?
Fill in the form or call 800-224-9245. We schedule a free camera inspection, show you the footage and send a written estimate.
How long does it take?
Most home repairs are finished in about a day. Longer runs, commercial lines and complex sites take longer, and we give you the schedule before we start.
