After ripping out some rubber baseboard, I discovered random holes all over the place. What would be the logical reasoning that these exist (if any)?
Edit: Hopefully I don't get completely flamed for this, but I'm asking because the basement that has this has been flooding recently and I'm wondering if these holes could be some poor attempt to "drain" water from the wall by the previous owner. The holes cover basically the entire room like this. Sorry for the misinformation I wanted to see what users thought without knowing this edited piece first.
