I don't think your flaking problem is a matter of which mulch to use.
The major difference is that some types last longer than others. The
mulch right against the house causes a lack of sufficient air
circulation. This could especially be a problem if the area is on the
north or east side, where it may not be getting enough sun to dry out.
As a general rule, it's best to keep mulch 2-3 inches away from anything
so as not to encourage dampness problems. This is especially true of
woody plants, by the way.

Also, make sure the area is pitched away from the house at 1 inch high
for every foot going away from the house so rain/water drain away from
the house.

Has anyone had issues with mulch eroding their foundation? I have
poured walls and the put dark hardwood mulch against it (for the last
three years). I noticed that the foundation was getting lighter (like
it was bleached) and when I went to investigate the areas that had
mulch against it, would flake and fall off. Fortunately I have caught
in time, but I need to know what mulch is safe, if any, to use by my
house's foundation.
Any advice?
Poor quality concrete perhaps? That's not happening to our 12 year old
foundation. We've had Pine bark nuggets against it all that time.

The house is 20 years old, and this has happened very recently. Are
you using the large pine bark chips?
