I’m hoping that somebody can identify and give me a reason why there would be holes through the foundation wall about every 2 feet. They are all at the same plane. In the photo, the wall coming from the left has them along the entire length of the wall. The wall to the right only has them going down that wall about 6 - 8 feet, then same goes for the opposite foundation wall from the opposite corner. This house does sit on a large lot that is sloping down toward this end of the foundation. Any thoughts greatly appreciated.
