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?
