I have a bi-level home with a walk out basement on lower level. The patio has retaining walls. When it rains or snows, we have water coming out from underneath the house and by the retaining walls. Is there some way we can fix this? Is this a serious problem? Our gutter is clean and the water moves away from the house. As far as we know we don't have water in the basement, since it is all tiled or carpeted. Any suggestions? By the way when we moved in we later found these clay pots in the dirt in the backyard, um not for sure why.
