I am building a small garage extension. I want the walls in plane with the existing walls, but the existing slab in this area extends 3" beyond where the sill plate will sit.
What is the proper way to deal with this? I was going to use pressure-treated lumber for the sill plate with a sill gasket underneath and caulk the edge. I was thinking of creating a small sloped curb out of stucco and lathe to help move water away from the sill. Or maybe I could use flashing but that would be ugly and possibly sharp.
I haven't been able to find what the "correct" solution for this scenario is.
