About Trenchless Technology

Trenchless pipe replacement is a method of replacing old pipe with new, with the same, or larger inner diameter. This is accomplished by pulling a hardened steel splitting head through the old pipe. The new pipe is attached to the back of the splitting head and is pulled in as the old pipe is split and expanded. The new pipe follows the path of the old one and lies in its rubble. The method of pipe replacement is NOT "slip lining".

Here is how it works....

Access holes are dug at each end of the pipe to be replaced. 
The location of these access holes are chosen for the minimal impact.
The replacement Polyethylene (PE) pipe is attached to the splitting head.
At the other end the splitting head and replacement pipe are pulled through the existing pipe.
The existing pipe, whether steel, cast iron, or porous material is broken to form a bed for the replacement pipe.


  • Lower cost for pipe replacement than existing open trench methods
  • No interruption of existing landscape, roadway, or structure
  • Replacement, not just pipe liner

Polyethylene Pipe

High-density polyethylene pipe is used worldwide for pressure water and natural gas utilities. PE pipe is not new in its various applications. It has a wide range of uses in pipe bursting, boring, directional drilling, slip lining, direct burial and trenchless replacement. In fact, PE pipe has been used successfully for over 35 years.

PE pipe is joined by heat fusion. The ends of the pipe are melted while being held together and allowed to cool. The result is a seamless connection that provides the same strength as any other part of the pipe. Normal pipe couplings can be used for attachment to existing plumbing.
