What happens here
Continue stacking subsequent courses of blocks, staggering the joints of each new course over the course below it for maximum strength and a professional appearance. As you build up, periodically check the level of each course. After every few courses, add more horizontal rebar into the core holes of the blocks, connecting them to the previous rebar or extending into the backfill area. Use a long handle shovel or rake to scoop crushed gravel into the core holes of the blocks and directly behind the wall for drainage.
Goal: Build up the wall's height with staggered blocks, integrated rebar, and drainage.
