Thanks.

By the way, funny, but this person, assuming I heard him correctly, at one
point, told me that he guesses that my wall probably has 200 gallons worth
of water trapped within it. He's not claiming that the meter tells him
that. Is there any reason to estimate that a cinderblock wall (45 feet
long) could really be holding that much water? I don't doubt that there is
moisture in the wall. I just doubt that we're talking huge quantities of
water. Could this really be true, or a bunch of hype? (hasn't rained for a
week or two, and I've never had any puddles on the basement floor, yet)

Interpreting results in a concrete block wall
can be tricky since almost all basement walls will
have some moisture.
