HDPE conduit is flexible which allows ease of installation in existing pathways, yet its stiffness can withstand crush forces at the calculated level for buried applications.

HDPE conduit is installed along highways or roads and in buildings. It is used to protect Power Distribution lines (600V secondary, <69kV primary) and telecommunication lines (network backbones), landline (wireline) and broadban; such as DSL Internet and CATV. The different installation methods are project specific and dictate what strength conduit is used.



Horizontal Directional Drilling (HDD) minimizes the impact to the surrounding area including less interruptions to traffic. This methods installs long lengths of conduit as much as 1,000-ft bores.

• Slip Lining innerduct used to increase capacity of existing pathways
• Pipe Bursting to upgrade service lines

• Plowing allows for long continuous runs along right of ways and the lowest installation cost relative to other methods.
• Trenching is a traditional and simple method where the conduit is uncoiled directly into the open cut.
