Leaking Basement----HELP
#1

I have a home I just bought and when it rains, water comes in........... not in a leaking sense but under the wall of the basement in one place I guess there seems to be a crack in the bottom of the wall letting rain water in. What causes this? How do I fix this problem from reoccuring? It's a home built in 1959 and the basement is block foundation and painted.
