Hello. The house is in northern NJ and was built around 1895. Please see attached photo of floor joist resting on the foundation brick wall. Some of the bricks are loose. You are seeing a corner of the wall there. The top of the wall is up about 3 feet from the outside ground. The bricks from the outside look and feel sound. How should I go about fixing the loose bricks? 
I was thinking of filling in mortar between the bricks 1 inch below the wooden joist and then letting it dry. Then using great stuff minimal expansion foam to fill the gaps between the mortar and foam. This is so the mortar is not in contact with the floor joist and to also air seal the air leaks.
