Block-Laying Basics

Laying the First Block Course A

Figure 3. Block courses start at the corners; a string stretched between the two corner blocks helps align the remaining blocks in the course, while pencil marks placed 16 inches on-center on the footing help the author space the blocks properly (A). When setting the last block in the course, he ori- ents it so that the flanged end is dry, which creates a bigger opening that’s easier to fill with mortar (B). After setting the block, he throws mud in the joint until it’s full (C), then uses a 34-inch tuck-pointer to pack the joint (D).
