I'd be willing to bet that if the concrete slab is cracked, they (The Rocha's) should check their home for inside wall cracks. If the concrete slab shifted, so did the entire home. This is not rare in our desert area, as our sandy soil shifts with miostier. Mr. Rocha the best you can do is apply concrete silicone, it comes in a gray color. This will prevent air and moistier from creating bigger cracks. It will be noticable but,hey..it won't get bigger. Good luck.
