I have a small hole in my basement floor from a leftover floor anchor similar to http://www.lowes.com/pd_79553-2191-50098___?productId=3044000. The anchor is now gone, and apparently over the years the hole has had some small amount of dirt and moisture pushing up through it.
I believe it is the source of a water leak during heavy rain. At the very least, it will be a point of concern for anyone buying the house. (I'm planning on selling in the next year).
I need to get this hole sealed properly. Preferably in a way that won't make it obvious that a hole was there (though this concern is very much secondary). What would be the right way to do this?
