Spray foamed crawlspace, now think I screwed up.....advice??
To start of, here is the history. Last year I noticed the fiberglass insulation in the crawl space was falling off the walls in some areas. I inspected those pieces and found them to be a little wet. I removed all of it and threw them out. Throughout the summer I noticed some wet/damp areas on the walls, but never any standing water or puddles. As the weather got colder (Ohio) I noticed the floor above the crawlspace to be colder then normal. I did some research and decided to spray foam the area.
I had an estimate and when they inspected it they said the moisture wasn't anything to worry about and the closed cell foam would take care of everything. (moisture barrier and air barrier)
So.....I spray foamed my crawlspace this week with closed cell style foam from gravel floor of foundation to the top of the sill plates.
Now I find some info saying that ANY water/moisture weeping or leaking in through the foundation/bricks may wick up the wall behind the foam and rot away the wood of the sill plates.
Did i make a mistake doing this? It made the crawl space much warmer, drier, and the bedroom floor above it is nice and warm.
Should I cut a one inch channel parallel to the top of the foundation just below the sill plate to allow any water to leak out? Maybe cut one along the bottom too?
FWIW...the slope around the house is going away from the house, the house was built in 1987, and the section of the true basement is completely dry.
