After the footings are dug and inspected, we lay rebar and pour the footings and allow them to cure. The next step is to mix the mortar and place them in tubs for the block layers. The masons start at the corners and use a string line to run the rest of the block section. Each block on the first row is checked with a level. A transit is utilized after the first course is complete to ensure there is a level line at the corners. Once the first course is laid, the remainder of the foundation moves at a fast pace. The top courses are filled solid. The foundation is parged and the inspection is called in.
