Grade was so steep the materials (back fill) washed away from the foundation & the back of the garage sank over 5 inches

When we put a 4 foot level on the floor over a 3 foot area the floor dropped more that 2.5 inches. After siting the footing we found it has dropped more than 5+ inches

Wall Drainage (perforated PVC pipe in ¾” crushed stone, minimum of 12” back installed behind the wall.
