While doing a HUD inspection in a foreclosed home yesterday I found something very odd in the basement. As I was going down the steps I thought I saw what looked like bullet holes in the block foundation. It is not unusual to find crazy stuff in foreclosed homes. Upon closer examination I discovered that the source was not from “my” side of the wall but from inside the brick or from the “other” home next door. These homes share a party wall. This condition was only on that one wall. My first guess was somebody was doing work on the other side and shot something into the wall. This is cinder block and as such would be 6-10" thick so my second guess is that something has reacted with stuff in the block and expanded it causing the stuff near the surface to break through.
Anyone ever see something like this?
