Lines / Slots in Brick?
In the process of having our Brick steps replaced. Some of you may remember my previous posts asking about suggestions. We love the brick we chose, and it seems the mason is almost done (brick is all set, but that is just in looking at it as a homeowner. Also, earlier in the week he mentioned coming back to "clean them" when everything was all done). My question is, I see many of the brick have a line or slot in them, in the middle. My guess is it's in the manufacturing as its a perfect slot, almost like a shallow saw cut. Since these are outdoor steps, I am concerned about moisture getting in them and blowing the brick apart over the summers / winters (we are in NJ). Is this a potential concern? Do brick get sealed after install to prevent this? I plan to ask the mason as well, when he comes back, but I wanted unbiased opinions. Thanks in advance.
