Municipalities See Value in Using Trenchless 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.
Pipe Bursting or Sliplining Technique?
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
Another trenchless technology method we use is sliplining. A smaller pipe is slipped into a larger pipe and pushed to the end. High Density Polyethylene (HDPE), FiberGlass Reinforced Pipe (FRP) and
PVC are all potential pipe candidates for sliplining. At the end of the process the new pipe improves the host pipe’s structural integrity repairing all possible infiltration.
Learn more about how we installed nearly 1/3 of a mile of HDPE pipe for the Portland Water District’s Mussey Road Project.
We can replace all manner of pipe including:
- Cast Iron
- Ductile Iron
Our trenchless excavation division can install water and sewer lines under existing structures, roadways or sidewalks with minimal excavation needed.
