Here’s how it is done.
- We excavate 2 access holes: one serves as a start/entrance pit and the second is an exit pit.
- We then send a cable through the damaged pipe. The cable is connected to a hydraulic puller. The other end of the cable is connected to a splitter cone that splits the old pipe. Behind the cone is the new pipe.
- As the hydraulic ram pulls the cable, the cone splits or breaks the existing pipe and pushes it out of the egress hole, leaving the new pipe in its place.
