 Yeah, sometimes you'll run into like there was a nail in there or there was a knot in the board and now there's concrete going across your expansion joint. So rather than try to chisel stuff like that out, we just notch the bottom side of the trim slab. You can cut that with a utility knife, you know, make a little kind of a mouse hole and have it go right over the obstruction. And on the top, it's going to be continuous and no one's going to even know that you did that.
