Well, true, but this is only a storage closet, essentially. No one will
be driving into the walls and hitting it. I figured just "gluing" the
footer to the asphalt should be good enough, however, it would be good
to pin it so it can't slide. So, I'll probably use a urethane product
as a glue and pin it with some long spike-like nails. I don't think
there is too much heaving due to weather in western NC, although there
might be some.
