Water drainage when sill plate is at grade?
Our house foundation and sill plate are at ground level. Obviously, this is unfortunate. The back yard slope slightly towards the house. When it rains hard, the rain water pools up against the foundation until it is about 3" deep and finally can leak between the sill and the foundation. Thankfully, we have a crawl space and no basement, so there is no interior damage. What can I do to solve this problem? I can't add more soil near the foundation as the sill is already at ground level. Here is a picture of the back of the house.
Thanks in advance,
