Trenchless methods
Trenchless Sewer Repair in Redwood City
Repair or replace a failed sewer line with little or no excavation.
What "trenchless" actually covers
Trenchless sewer repair is not one method. It is a family of ways to fix or replace a buried sewer line from inside the pipe or through one or two small access pits, instead of opening a trench along its whole length. The two that do most of the work on residential lines are cured-in-place pipe lining, which rebuilds the pipe from inside, and pipe bursting, which replaces it along the same path. Sectional point repair handles a single bad spot, and spray-applied lining handles cast iron with too many bends for a felt liner.
How the method gets chosen
Every one of them starts the same way: a camera inspection that shows what the pipe is made of, where it fails, how deep it is, and whether it still holds its shape and slope. A line that is round and holding grade can be lined. A collapsed or bellied line cannot; it gets burst or replaced. One crushed joint on an otherwise sound line gets a point repair. The footage decides, and you should be shown it before anyone quotes a price.
When trenchless is the wrong answer
A lateral that has been undersized from the start, a run that crosses a foundation footing within inches, or a line with a long stretch that has lost all grade may be better served by spot excavation or a new route by directional bore. An honest contractor says so. The point of trenchless is not to avoid digging at any cost; it is to avoid digging that does not need to happen.
What to expect on the day
Cleaning with a hydro jetter, a camera pass, the repair itself, a post-repair camera pass, and, where the work touched the right-of-way, a city inspection. Most residential jobs are done in one day with water off for a few hours. The permit is the contractor's job; ask who is pulling it.
