Some are 1/8 of an inch taller than the others. As we were building the wall we noticed it was a little uneven and realized it was the brick - even though the difference was slight. The brick manufacturer took all the bricks back, made a new batch. We got the new batch recently and started building the wall again and the same freakin’ thing! - the bricks are slightly different heights.
I don’t know how they could allow that happen again. You would think they would have some quality control, especially if they already had an issue with it. Anyone ever encounter this?
