Trenchless Sewer Repair

Our process brakes the old pipe out of the way and replaces with new pipe. The new pipe can either be the same size as the old pipe or, if the old pipe has reached its flow capacity, we can often install a larger pipe.

Two holes, a starting point and an end point doing minimal damage to your property.

How we do it?

First, we locate the old pipe and inspect the interior using a camera with ridgid locator. The camera takes video that is displayed on a remote screen. It allows us to identify the condition, direction, location and depth of the pipe. We then locate the beginning and the end of the pipe.

Small excavations (approximately 3’ x 6’ each) are dug at both ends, and the old pipe is cut away in those locations. We feed a high-strength steel cable through the old pipe from excavation to excavation, then the pipe bursting machine is attached to one end. On the other end, the new pipe is connected to the steel cable. At the front of the new pipe is a steel cone with a knife edge. This cone splits and expands the old pipe, making room for the new pipe to take its place.

Note: If an existing sewer line has any bellies, this is not recommended.
