Why Does This Happen?
During the original construction of a lot of homes, small metal rods, called tie rods, are inserted into the concrete form in order to hold the inner and outer forms together, and provide the structure with which the concrete can be poured. They are placed around 18 inches apart from one another, sometimes in two rows.
After construction, they are usually either removed entirely, leaving a hole. The builders may make some attempt to fix the tie rod holes, at least aesthetically, by covering them with hydraulic cement and a coating, but over time this can wear off, revealing a very vulnerable point for water to enter.
Water takes the path of least resistance, and so will always flow through the tie rod holes if possible, given that they are essentially hollow all the way through. This is why the problem is so common. If water finds its way in, then it will also end up in your basement!
