Garage is under family room. Only finished wall is in the back and
other side is the basement. There has always been a minor water
problem from the garage to the basement in the winter when snow melted
from the cars. It would leak under the finished wall via approx 1/4
to 1/2" gap between bottom of wall and basement/garage floor. Never
an issue until this year with the now finished basement and tile and
rug now on the other side of the wall.

Looking for an easy fix, something like plastic moulding maybe (???)
that could possibly be glued to the wall and floor. Any good and
easy ideas?

Thanks!!!
