Reply to comment by jaaassshhh in Is it okay to spray foam the gap between drywall and a basement slab? by jaaassshhh

Our builder left a gap like that so that if there's ever some moisture intrusion into the basement - leaking plumbing, water coming in through the wall or slab, etc - it doesn't immediately wick up into the sheetrock.

Maybe just put some trim over it?

This is exactly what it’s for. You just need to put your trim of choice down to the concrete that will act as the final barrier.

You could pack it with something porous like rockwool.
