Trenchless Sewer Repair

Underground pipe repair or replacement performed without excavating the full length of the line, using specialized equipment inserted from access points.

Trenchless sewer repair covers several methods—pipe bursting, CIPP (cured-in-place pipe), and sliplining—that fix or replace damaged sewer lines from inside or with minimal ground disturbance. Instead of tearing up driveways, roads, or landscaping to access the entire run, technicians use camera inspection to locate the problem, then deploy equipment through existing cleanouts or small access pits to repair or reline the pipe in place.

Pipe bursting pulls a new pipe through while fracturing the old one outward; CIPP involves winching a resin-coated liner through the line and curing it in place to form a pipe-within-a-pipe; sliplining threads a smaller diameter pipe inside the damaged one. All three avoid the cost and disruption of a full excavation, and the cure time is typically 24 hours or less before the line returns to service.

The trade-off is upfront equipment and crew specialization—you'll need specific training, certifications, and expensive gear to execute these jobs. Trenchless makes sense for long runs, deep pipes, or jobs under infrastructure or finished surfaces where excavation is prohibitively expensive or impossible. For short runs or surface lines, straight replacement with a shovel and ditch witch is often faster and cheaper.
