Duluth sewer problems. Minimal digging. Lasting repairs.
Sewer lining is used when a pipe has multiple defects but is still structurally suitable for rehabilitation. It is the preferred method when the pipe retains its shape and failures have not caused a structural collapse.
The process begins with a detailed camera inspection and extensive cleaning of the existing sewer line. Specialized cleaning equipment removes roots, buildup, burrs, and debris to prepare the pipe for lining.
Once cleaned, a custom liner is measured, cut, and saturated with epoxy resin. The liner is installed through an inversion process that presses it tightly against the existing pipe walls. A blue-light curing system hardens the epoxy to create a new seamless pipe within the old pipe. Any branch connections are reopened using robotic cutting equipment, and a final camera inspection verifies quality before we leave.
The result is a structurally sound sewer line with minimal excavation and significantly reduced restoration costs.
