Does anyone have experience with HDPE or PVC Conduit in extreme weather environments?
I'm working on an outdoor project which will need conduit run (totally underground) in 30-40ft runs. The weather here fluctuates from -60F in winter (ambient temp) to +95F in summer. The ground freezes about 10 feet deep in the winter and we get frost heaving.
Can I expect the HDPE or PVC conduit to survive in an environment like this or should I go with RMC (or another alternative)? I read that they tend to do a lot of contracting and expanding with temperature changes and get very brittle when cold, so I'm thinking it isn't a good choice. Our soil here is not corrosive, so that isn't an issue for a metallic conduit....
Thanks!
