It has happened in steel conduit for sure. I don't know about HDPE.

Due to obstacles, that's as deep as it was realistically going to go. Now somebody is wondering whether ice in the conduit is going to be a problem. We're assuming in the long run water will always get in, but the question is whether it'll hurt the fiber when it freezes. The person doing the wondering speculates that when the ice expands it will crush the cable and damage the fibers. Is this actually possible?
