Pretty much agree hear, as long as the plastic is against the foundation
when you backfill, it isn't going to go anywhere. The small amount of water
that might get behind it probably isn't going to matter. I don't think you
want the earth bone dry anyway, it might turn to dust and end up being a
problem - depending on the grade, when the earth on to gets wet it could
begin to slide away.

I am looking for any suggestions as to what I can use as an adhesive
to glue the edge of the plastic to the outside of the foundation of
the house....it has to be a weatherproof/waterproof bond that will
continue to hold the plastic to the house for many decades, if
possible.

Why don't you just run the plastic to the foundation and put soil or
rocks over it? I doubt that any adhesive will do what you want, and as
long as the plastic dives down into the trench at a good angle, water
won't run uphill.

If you absolutely have to attach the plastic, think about a mechanical
connection, perhaps a sheet metal reglet shot onto the foundation wall
with ram studs. I think that's too much. Once the plastic is covered
with dirt, it won't go anywhere.

(just to clarify, the plastic will be attached to the house, and then
scoop under the entire french drain assembly - so from the bottom up,
it will be: Plastic, stone, PVC stone, landscape fabric, stone.)

The PVC should be at the bottom. Plastic, PVC, stone, landscape fabric,
stone. Use 2" washed drain rock. Pea gravel will plug with silt. If
you have a couple feet of stone, skip the fabric, which will also plug
over time.

I'm taking your situation at face value - the water is sheeting down a
slope and penetrating the basement wall. However, 9 times out of 10, if
the basement is wet, the water is coming off of the roof. Downspouts
should run into a tight line (NOT perforated) and discharge well
downhill from the house or into a storm sewer.

I'd combine the above advice (some sort of strip anchored to the
foundation) with a bead of something like sikkens or np1 between the
plastic and the concrete.
