Main Sewer Line Lining
Larger mainlines under streets, parking lots and buildings, relined between access points without closing the road or tearing out pavement.
The details, in plain English.
Mainlines collect flow from many fixtures or many buildings, so a failure there is costly and disruptive. Excavating a main under asphalt, concrete or a building means cutting pavement, shoring trenches and rerouting traffic.
We reline mains in sections from manhole to manhole or cleanout to cleanout, with bypass pumping when flow must be kept moving. A structural liner restores the line to service with the surface left intact.
Best for
- Commercial and multi-family mainlines
- Mains under pavement or buildings
- Lines with repeated blockages and root intrusion
- Properties that cannot stop operating

Questions, answered
How long does a mainline lining job take?
It depends on length and diameter. Short sections are often a day, and longer runs are phased so the property keeps operating.
Do you handle bypass pumping?
Yes. When flow cannot be stopped, we plan bypass as part of the job.
