Three common pathways

Trenchless is a category—not one universal repair

Cured-in-place pipe lining

A resin-saturated liner is installed inside a suitable existing pipe and cured to form a new interior pipe surface.

Potential fitOften considered for cracks, joints, or root entry when the host pipe retains enough shape and access is available.

Pipe bursting

A replacement pipe is pulled through the route while specialized equipment breaks apart the old pipe.

Potential fitMay fit lines requiring full replacement when the route and utility conditions permit pulling a new pipe.

Targeted or semi-trenchless repair

A contractor may combine limited excavation with internal repair methods to address a specific failed section.

Potential fitMay fit localized damage when a full-length rehabilitation is unnecessary or unsuitable.

What the inspection must answer

Questions to ask before choosing a method

Is the pipe cracked, collapsed, bellied, offset, or heavily deteriorated?
Can the existing pipe support a liner?
Are there sharp transitions, diameter changes, or missing sections?
Where are other utilities, trees, pavement, and foundation elements?
What access points and permits will the project require?
What warranty applies to the recommended method?

No honest site can promise trenchless repair before inspection.

A collapsed or severely deformed line may require excavation. The goal is not to force one technique—it is to choose a durable solution for the actual defect. Review the broader sewer-line replacement decision before comparing methods.
