Pipe Bursting & Trenchless Sewer in San Jose, CA
Pipe bursting is how we replace a sewer line trenchless. Instead of trenching the whole yard, we pull a bursting head through the old pipe. It breaks the old line outward into the dirt and drags the new pipe in behind it.
Signs you need this
What it saves you
Two holes instead of an open trench from the house to the street. Your driveway stays, the big tree stays, the walkway stays.
On a lot where the line runs under concrete, that is most of the cost of the job right there.
Better to hear that open trench is the right way before the work starts than halfway through it.
When it will not work
Bursting needs a clear path through the old pipe. If the line is collapsed flat, or badly offset at a joint, the head will not go through. Some soil and some utility clearances rule it out too.

Questions people ask
How does pipe bursting work?
We dig two access pits, one at each end of the line, and pull a bursting head through the old pipe. It breaks the old line outward into the dirt and drags the new pipe in behind it.
Will trenchless sewer replacement tear up my yard or driveway?
No trench from the house to the street, just two holes that get backfilled. Your driveway stays, the big tree stays and the walkway stays. Where the line runs under concrete, avoiding the trench is most of the cost of the job.
When will pipe bursting not work?
It needs a clear path through the old pipe. If the line is collapsed flat or badly offset at a joint, the head will not go through, and some soil and utility clearances rule it out too. That is why the line gets a camera first.
Do you also do open trench sewer replacement?
Yes. When bursting is not the right way, open trench is, and it is better to hear that before the work starts than halfway through it. See sewer line repair and replacement.
