Standard?


As long as this gap was filled, I don’t see an issue.

In general glass block joints should be between 1/8" and 5/8" using IRC R610.9 as a guide … icon_wink.gif

This 2" area isn’t a joint between glass block. It’s a 2" thick (tall) cement base that a glass block window is sitting on.

The mortar that masonry units sit on is called a “bed joint”, and should be in the range given. But unless there is deterioration I don’t think it’s a huge problem.

As long as there is mortar under the block and it is not cracked, broken or lose , it should be fine. Most glass block are laid with shims too. I bet money that there is a 2x4 or something under the first course. icon_wink.gif


Glass block are impossible for a mason to cut. Glass block and all masonry units are made a certain size. Now with real block or brick you can cut it to a dimension that does not hit coursing. You can do that with glass block, they won't cut. So you are left with a real big bed joint at the bottom, to reach what ever height they had to hit. Glass block are very hard, (for good masons) to lay. So the height can not be made up in the bed joints.
I bet they laid the first course and left it for a day to set.
