Common questions about trenchless sewer work

Trenchless sewer repair covers methods that renew or replace an underground sewer line with limited excavation—typically small access points rather than a continuous open trench. The two most common residential approaches are pipe lining (CIPP) and pipe bursting.

Pipe lining inserts a resin-coated liner into the existing pipe and cures it to form a new pipe inside the old one. Pipe bursting fractures the old pipe outward while pulling a new HDPE pipe into place. Lining suits pipes that remain structurally usable; bursting is used when full replacement is needed or the host pipe cannot support a liner.

The purpose of trenchless methods is to avoid a continuous trench. Access is usually limited to one or more small pits or existing cleanouts. Some surface disturbance at those points is still required, and restoration is part of the work.

No. Severe collapses, large bellies, extreme misalignment, or certain site conditions can make open-cut repair the practical choice. A camera inspection is the usual way to determine suitability.

It means the full length of the pipe path is not excavated. Small access points are still needed. “No dig” is a common industry phrase; it does not mean zero ground disturbance.

Inspection findings are the basis for recommending lining, bursting, or traditional excavation. Without a clear view of the line’s condition, method selection is guesswork.
