Because it’s trenchless, pipe bursting is the preferred method for replacing old pipes in urban areas where disruption to surrounding utilities, local residences, businesses and the environment are a consideration.

Pipe bursting involves using a winch to pull a high density polyethylene pipe through an old pipeline of equal or smaller size. The old pipeline is shattered using a high-powered tool with special bursting heads that smash through the old pipe. When pulled into the old pipe, the bursting head breaks the pipe into pieces, enlarges the hole, and pushes the fragments into the surrounding soil. This limits pipe bursting to pipes that can be fractured and to soil conditions that will absorb the old fragments.  

An added benefit of using HDPE pipe for pipe bursting is its suitability for non-pressure applications like sewer lines. Because of its smooth inner walls, HDPE pipe minimizes the chances of developing stoppages.
