Pittguy12, thank you for the response.
The 8" slab thickness will be maintained across the drop location with slab reinforcing draped across the drop (#4 @ 12" O.C. Ea. Way Top & Bottom).
See attached for visual.
Given this image, do you still think the #3 corner bar is necessary...
I have a slab-on-grade foundation system with several depressions for showers. Are these drops (3" drop in an 8" thick slab) considered re-entrant corners?
I have re-inforced for potential vertical cracks across the drop, but am concerned about possible re-entrant corner issues.
Do I need...
