Our home was constructed in the 1920's, in Iowa. While cleaning the basement to remodel, we were scrubbing the walls. chunks of concrete patch started to fall off, revealing a 2 1/2 to 3 foot board at the base in the corner. the board was hollow behind it, revealing the sand poured around the foundation. further inspection revealed that while the rest of the wall base is concrete, but a mere 3-5 inches thick. I removed some sand to seeif the stone had crumbled behind the poured concrete that covers it, and discovered that the rock foundation resumed roughly 1 foot above the basement floor, and runs the length of the wall, apparently. My questions follow-
1-why would there be a 1 foot gap between the stone foundation, and the
2-Why would they not reinforce this gap when they poured the concrete over
3-Why would a board be used in the corner?
4-What should be done about it?
