Ok, after posting my problem here and elsewhere, the problem with the
foundation seems to be soil erosion from underneath of it. Many have
suggested either packing dirt into the void or concrete, but that
doesn't address the cause of the gap in the first place.

As those who have been following from my photos, the concrete pad
that sits in front of the eroded area is about 4x4 feet and not
easily movable. It does slope higher on the side opposite the
foundation and the unfortunately needs it would have to be lifted so
the slope would be higher on the foundation side. However, after
looking more at the area yesterday, I find that a much larger area,
say 2-3 feet beyond the concrete pad is also either level or sloping
towards the foundation.
Some suggested cleaning the gutter, but there is no gutter as this is
the on the side of the angled part of the roof. The gutter you saw
at the end of the gap is at the bottom slope of the roof and really
doesn't help with drainage for this part of the foundation at all.

I'm looking at a quick and simple solution. A benefit is that the
house overhangs the foundation by about 3" or so. I was thinking of
a couple of ideas. Since it would be nearly impossible for me to
lift the pad in order to elevate the foundation side, what about
something placed over it. One person suggested pavers, but I was
thinking of a sloping concrete form, placed under the lip/ overhang
of the house and draining the water out and away from the area of bad
drainage. Is there such a concrete form? I swear I've seen them,
they look like a triangle and about 3' across by 3' long and quite
heavy. Aren't these also in composite material form? Another idea
I've thought about is placing some sort of "gutter" under the house
overhang and redirecting the falling rain water toward the downspout
you saw in the photos. I don't like this idea as well because it
only addresses one small part of the sloping toward the foundation
and may not do much good, the concrete/ composite form idea is better
to me.
If anyone has any other suggestions, or can suggest where I might
find the form I'm speaking of, I would appreciate it.


It's not hard to lift a concrete pad - just time consuming.

Put a layer of pavers in the hole. Put a bottle jack on top of the stack,
under the pad. Jack away.

If the pavers move down, remove the jack and add more pavers. Repeat.

Eventually the concrete pad will move up to where you want it. Add more
pavers to the stack until the stack is flush with the pad. Remove jack.
Cover the whole mess with dirt.

What you're doing is essentially the same thing as a foundation levelling
operation, albeit on a much smaller scale.
