The pipe bursting strategy uses the infrastructure that is already in place surrounding the sewer line. The equipment will act as a virtual guide for installing new pipes very little to no disturbance the surrounding ground. The existing pipe will either be replaced through the use of a static polling head or a pneumatic hammer. From this point the old pipe will be broken up and shifted outward into the surrounding soil. The new pipe will then fill the space that was inhabited by the old pipe.

Due to the fact that this is simply a process of moving one pipe into the space that was resided by the old pipe, is typically an exchange of one pipe of a similar size to a different.

The new pipe will be placed into the launchpad with the expander that helps guide it to the location of the old pipe and fitted correctly.

Additionally, the cutter will be installed and the bursting rods will be secured into place At the end of this stage, the process is ready to get started. And now the process of pipes bursting can begin.


During this stage the cutting rods and bursting rods will work together in an effort to break apart the existing pipe which will be dispersed into the area soil. The new pipe which will be led by the expander is pulled into the ground to fill the void left by the previous pipe. Once this is completed, the additional equipment will be removed, had the and taken back to the business.
