Municipalities See Value for Pipe Bursting & Pneumatic Tunneling Technology
Are you a municipality with deteriorating water or sewer lines or, do you need to upsize smaller mains to larger ones? Our approach is well proven and effective.  It uses existing utility routes; reduces construction, design and planning costs; and minimizes disruptions to traffic flow. It’s safe for both workers and pedestrians.   

How Does Pipe Bursting Work? 
Our pipe-bursting technique replaces a malfunctioning pipe by running a bursting head through the existing pipe. An expander follows the bursting head, pushing the surrounding soil away, which, allows the space for the new pipe to be pulled through. This technique is highly regarded because it takes up less space and is completed in a fraction of the time of traditional trench methods.

We can replace all manner of pipe including:

  • AC
  • Cast Iron
  • Clay
  • Concrete
  • Ductile Iron
  • Galvanized
  • PVC

Our pneumatic tunneling division can install water and sewer lines under existing structures, roadways or sidewalks with minimal excavation needed.
