Pipe Bursting - “Trenchless” Sewer Replacement Systems

Pipe bursting is a more environmental friendly method of replacing your sewer lateral. This is due to most of the replacement being done underground, without disturbing your landscape.
What We Do
Trenchless Replacement and repair of Sewer lines and Water lines is a relatively new technology that is quickly becoming a favorite of homeowners everywhere. Pipeline Excavation is one of only a few companies who use this type of service in the Tri-State area.

“Pipe Bursting” is a technique for replacement of existing pipes. The existing pipe, once burst, becomes the guide path for the new pipe being installed.

This technique bursts the old pipe and in so doing displaces the fragmented old pipe into the surrounding soil. This creates a hole of roughly the same dimension as the original. If a larger diameter pipe is to be installed a larger 'expanding cone' is used to increase the size of the hole. Once done, the new pipe is pushed or pulled into position.

How We Do It
Our team of professionals arrive to the job site on time and begin the small amount of digging required for your new 'Trenchless' Pipe replacement.

Two access points are required for this, the beginning and the end and is usually no larger than a 4’ X 4’ hole to accommodate the machinery. A new pipe is winched through the old pipe, leaving the old pipe in the ground to act as a sleeve or guide for the new pipe. Once the new pipe is reconnected at the beginning and the end, the area is backfilled, leaving the rest of the property untouched

Why We Do It:
'Trenchless' vs. Open Trench Excavation
Open Trench - Excavation uses heavy excavation equipment to dig a trench to lay a new pipe, bury it, and then attempt to restore the surface to a reasonable condition. Sometimes, this is the only option if the pipe needs to be rerouted or if the existing pipe is completely collapsed.

Trenchless - is just that. Underground, out of sight and without damage to your landscaping.

What are the benefits of pipe bursting?

Pipe bursting has several advantages over open-cut trenching:
  • Pipe bursting allows for replacement of pipes without disturbing surface structures.
  • Potential problems with existing pipes are minimized because pipe-bursting methods follow the existing pipe path.
  • For smaller sizes of pipe, pipe bursting is the only trenchless technology that can be used to upsize the existing pipe.
  • Because it is trenchless, excavation is minimized, which lessens effects on existing landscaping and structures. The bursting heads on the piercing tool can be removed at the end of the line so that the tools may be removed through the new line.
  • Pipe bursting reduces the amount of site restoration required.
