Hi Pam Gutter run off is the most common reason for water going down a basement wall and finding a way in. Gutter run-off MUST be directed away from the house to where it will run away. As Mamaliz points out, sloping the ground around the house so that water will naturally run away from the foundation is also very important in keeping water away from the basement wall. I have personally worked on 100+ year old houses with holes through the old basement walls large enough to easily pass a screwdriver through and into the outside soil, but the basement had no moisture (and this was a wet climate). Why? Water was not allowed to run up against the outer wall......it was engineered to run away from the house.
