Anyone here with experience making a crawlspace moisture-resistant (with
plastic membranes or other means)?

Please read the question carefully before answering. Not looking for
speculation or even helpful links to things I can find myself on the
web. Looking for personal experience. (Funny anecdotes accepted as well.)

Reason for the question is a client with a damp crawlspace, dirt floor,
and an overly-humid house. (Older house, vents installed, but no
circulator, dehumidifier, etc.)

I covered the ground with 10' wide strips of heavy plastic sheeting,
each side overlapped about 10" and taped with tape designed for
plastic sheeting. Around the perimeter, I staked it down 16d nails
run thru a plactic cap from roofing caps. I have found no signs of
moisture in my crawl space. However I did get a few holes in it where
mice got under it and chewed their way out. A few handfuls of Decon
thrown under there once a year stopped that problem.
