Hi Perry, any conduit will end up with water inside unless it is
pressurized. The french drain or septic line material has slots that will
allow
water to enter or exit. The advantage is that any collected water will
eventually drain out instead of just constantly soaking the cables.

I still don't understand the "French drain" stuff. I have a 70' run of
two
3", one 2.5", and two 11/4" conduits from my tower to my house. At each
end,
I have the conduit terminated in metal 18" X 16" X6" NEMA 4 boxes. The
boxes allow the conduit to breath and in the seven years they have been
installed, all I've found in them is cob webs. I just pulled some Cat 5E
in
one of the 11/4" runs and it was as dry as a bone.
Like a lot of the Southeast we are currently in the middle of a freezing
lake... flood, then ice, finishing with snow. In other words a lot of
moisture. If I had used the "French drain" my coax coax would be
swimming.
