A *hole* is opening up between two concrete pipes in my driveway under
the rock and dirt that goes over my ditch. The hole is about 3 inches
in diameter and I guess rain has disolved the dirt underneath the rock
just above the two pipes. I can see that the two pipes underground
were not joined together well and there is about an inch or so of
distance between the two pipes. Short of digging them up completely,
pushing the two pipes together and then putting dirt and gravel back
over the two pipes (which would take some time) what advice would you
give to fix the problem?

Shove section of liner down the culverts. (Are they big enough for
you to slither down without drowning or getting stuck?) Sheetmetal
or cardboard should do. Then squirt a really wet concrete mix
down the hole until it starts oozing around the liner.

What you said sounds like a pretty good and easy idea..."Shove section

or cardboard should do. Then squirt a really wet concrete mix
down the hole until it starts oozing around the liner." And these
pipes are only about 12 inches or less outside diameter.
I know I will need to schedule a Saturday soon to dig up all around it
and see how bad the problem really is, unless I use some cardboard or
sheet metal as you say and slide it up "inside" the pipe to keep from
actually digging out the pipe on the outside. Thanks.

Just curious...is my Fernco coupling suggestions out of the running as
a possibly more permanent fix?
