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
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:
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?
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
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.
