Are you sure its the same stuff? I have hit it with the wide end of a pic,and it did not break it. Granted,I only hit it once,but,it saved me from cutting thru low voltage lighting wire. I am not sure abot it being rated for underground,but, I doubt it.but,I would not think so. Someone asked why it was blue earlier.Blue signifies power circuits. they make yellow for communications cables,and red for fire alarms. I use it for low voltage wire in areas where I may have to dig in certain areas of beds. I also use it around trees where I have landscape lighting and/or inground speakers as a precaution should I have to replace plants. When going across a lawn with LV wire,I am down 10"-12" in sch 80 even though the wire is rated direct burial.I want to give any critters underground a hard time in case they decide they want to chew thru wire.
