Locate the Corners
Figure 13: Laying the first course
The first step in building a concrete masonry wall is to locate the corners of the structure. In locating the corners, you should also make sure the footing or slab formation is level so that each builder starts each section wall on a common plane. This also helps ensure that the bed joints are straight when the sections are connected. If the foundation is badly out of level, the entire first course should be laid before builders begin working on other courses. If this is not possible, a level plane should be established with a transit or engineer’s level.
