I have a house that was built in the 1950s. They probably remodeled the basement in the 1970s. I bought it in 1999. I am redoing the basement again.
When I lifted up the existing tile flooring, I was quite surprised to find a series of holes on the concrete floor around the inside perimeter adjacent to the exterior walls of the "finished" portion of the basement. They're big enough that I can stick the tip of my pinky finger in them, but not the whole finger. They're all approximately 27 inches apart, and they're very nicely drilled. Clearly, they were put there intentionally.
My main questions are:
1. What the heck are they for?
2. The reason I posted this on a termite board is because I was searching on the web and a few sources said similarly described things were holes drilled for termite treatment. Is it true they used to do that at one point to treat for termites? Do these sound like old termite treatment holes?
3. If this is a way to treat for termites, what's the logic? How does a hole in your concrete treat termites? Were they presumably once filled with something?
4. As far as I know, I don't have termites. We had an inspection when we bought the house in 1999, and all seemed well. Can I fill in these holes before I lay down my new flooring? If I did have termites now or in the future, are there better ways to treat for it.
Thanks so much. I love your forum. It's very helpful.
