I'm seeing a lot of this http://tinyurl.com/cxmbhar around here.
Tried searching, and came up with a lot of hits on "mole"
devices, but they all required a sizable hole dug at the
beginning (and end?) of the run and the run seems to have to be
straight-line and level: http://tinyurl.com/bqgbsfo
Whatever is putting in that orange stuff seems to be doing it
without any holes at either end of the run. It's as if the mole
can be directed down, curve under the surface, bore to the other
end, and then re-surface.
Or am I missing something?
If not, can anybody hang a name on the device that does this?
I should add that his is totally-idle curiosity. I just went
through the conventional process of digging a trench and laying
conduit and the job's done.... but it was sooooo messy and
labor-intensive that seeing installations like in the first link
has me going on how it was done.
