Can moles undermine house foundation?
 

I have a lot of moles (or at least mole tracks) in my lawn. A mole
tunnel also shows up at the edge of the house foundation. Is it
possible for these moles to dig underneath the foundation (house
construction is on a concrete slab) and cause structural damage? I've
noticed a few small cracks above a door frame and wonder if there is a
connection to my moles.
