I have a concrete driveway. Where it meets the poured concrete house
foundation, there is a hole about two inches wide that goes down to
the dirt. It’s under the siding such that I can’t clean it and smooth
it for good patch adhesion.

What should I put in it? Should I do it in layers such that each
layer dries before applying the next layer?

Why do you want to fill it in? Is it just for looks or is
there a structural issue?

Without knowing more, I'd say the reason for wanting to fill it is
obvious: to prevent water from getting into/under the house.

For this purpose, cleaning the hole as best as possible, then throwing
some cement into it, should do the trick. It doesn't need to be pristine
for the cement to form a good seal, I wouldn't think. Either flush it
out with water first, or stick a vacuum hose in there and suck out what
debris you can.

Thanks for the replies so far.

through a hole.

I can't clean it because of access issues. Flushing it with water
won't work, as it will just fill with muddy water. A vacuum won't
fit. The best I can do is blow.

Well, then blow as best you can (accompanied by probing with a
coat-hanger wire or some such to dislodge debris), then fill with
patching concrete of some type.

However good the repair is or isn't, it will be a hell of a lot better
than having a hole there.
