What is the process of aligning the bottom edge of each block with the top edge of the block below called?

The process of aligning the bottom edge of each block with the top edge of the block below is referred to as "facing the block." This technique is essential in masonry to ensure that the blockwork is not only structurally sound but also visually appealing. Proper alignment helps to maintain uniformity in the wall, which is crucial for aesthetics and structural integrity. By facing the block, masons ensure that each block fits snugly against the one beneath it, creating a level and consistent surface throughout the masonry work. This alignment is fundamental in preventing issues such as uneven walls, which can arise from misalignment during construction.

In contrast, setting blocks involves placing the blocks in their intended position but does not specifically emphasize the alignment of edges. Mortaring refers to the application of mortar to adhere the blocks together and fill joints, while jointing is the process of finishing the mortar joints to enhance durability and appearance.
