I'll bet you've seen big rolls of it on the back of utility trucks before. Probably blue or red.

We use it under raised floors in some of our systems we build. While I have not personally worked with it, it seems pretty durable.

We used to use it pretty regularly in residential to provide a chase for tv cable and phone cable to be run underground from the street box to the demark for the house. Both the cable co. and the phone co. now insist on a min 1" pvc conduit for the same job.

Please read Charlie's reply again. You cannot use this wiring method at all in the 2002 NEC, and in the 2005 it must be outdoors and concelaed.
