Generated explanation

A front-view section of a garage shows a concrete floor slab supported on gravel and soil between foundation walls with footings and wood wall framing above. Backfill settlement beneath the right side has allowed a portion of the slab to drop and slope toward the foundation wall. A water-flow arrow shows drainage toward this low area beside the wall rather than away from it. Spalling is depicted on the foundation near slab level, and the annotation links this damage to salty water accumulating against the wall because of improper slab slope.
