High-density polyethylene pipe is the workhorse of trenchless installation. It is flexible enough to be pulled through bores and burst paths, tough against corrosion, and fused into one continuous length with no joints to leak or let roots in. It is used for sewer force mains, water lines, gas and conduit crossings, and storm applications. We install HDPE with the right fusion, handling and testing methods for the job.
We select the diameter and wall for your use, fuse the pipe into a continuous string with heat fusion equipment, and pull it into place through a bore, burst path or slip line. We test the pipe, make the connections and document the work. We explain how HDPE compares with other options and when another pipe is a better choice.
When this is the right call
Root problems
Fused joints keep roots out.
Pulled or drilled installation
HDPE flexes through curves and bores.
Long runs
Continuous pipe can be installed in long pulls.

HDPE Pipe Installation: answers
Is HDPE strong?
Yes. It is tough and flexible, and it handles ground movement well.
Can HDPE connect to old pipe?
Yes, with transition fittings made for the pipe.
Is HDPE used for drinking water?
Water-rated HDPE is used for service lines, and we select pipe to fit local requirements.
How is HDPE fused?
A heated plate melts the ends, which are pressed together to form a seamless joint.
