Stone "Foundation"—Sill to Stone Sealant

I have a field stone foundation under a kitchen off the main house. The house is over 100 years old, the kitchen is at least 80. Underneath is a crawl space. When the foundation ruptured last winter I decided to suspend the kitchen on a post & beam setup and patch the wall only to seal it from the outside. It will no longer be load bearing.

The patchwork with the mortar seems pretty straightforward. However, I am paranoid about future winters causing the wall to heave and shove up the corner of the house like last year. So I want to jack the kitchen up 1/2" or so above the wall and seal it with something flexible which will adjust with the wall over time.

Does anybody have a recommendation as to what I should use for this?

Should be spending your time and money fixing the real issue, the foundation.
About the best you can do is spray in some expanding foam.
