I bought a Cape Cod built in 1948 a year ago. I have a sump in the
basement. It is unfinished, but I am thinking of finishing it in the fall.
I don't usually get any water in the basement as long as the sump is
running, but earlier in the week we had 2 bad storms that made my pump run
about every 5 minutes. Kept the basement dry, except in 1 area I got a
puddle. Basement also has tiles down, and along the seams of the tiles it
is moist there when I get heavy rain. What can I do about this? I am
almost positive the water is coming up from under the flooring, not in from
the walls.

Thanks
