I need to make some weep holes in this retaining wall. I’m not a bricklayer or anything but have the basic tools. I was going to chisel out one brick and replace it with a half brick every few feet but then realised the wall is 2 bricks thick. The second image is how it is on the neighbors wall adjoining. Any suggestions appreciated. Cheers

Hi, I need to replace a few bricks in this retaining wall but am told that these bricks are no longer manufactured. Any ideas for a reasonable match?
