Pipe bursting can be used to replace water lines, drain lines, sewer lines, etc., with diameters as small as 0.5″ up to 18″. It’s a great technology to use when a pipe is starting to collapse or is no longer circular. Besides reducing the destruction of your home or yard, an added benefit is that the pipe diameter can remain the same or in some cases even be enlarged.
The pipe bursting method can split clay, cast iron, cement, transite and ductile iron pipes. This technique can be used to replace lines under yards, sidewalks, driveways, homes, highways and other structures that make traditional digging expensive or impossible.
The process for both water and sewer lines is similar.
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.
Which would you rather have? Two holes in your yard, or a long trench?
The second hole is across the street and not visible in this photo.
