What happens here

After placing each layer of blocks, it is crucial to clean off the top surface before adding the next course. The video demonstrates using a leaf blower to remove any small rocks or debris. This step is critical because even a small rock between layers can cause an uneven course, leading to cascading alignment issues in subsequent layers of the wall. The cleaning ensures a stable and perfectly level surface for each new block layer.

Goal: Ensure a clean and level surface for each subsequent block course.

now here's a step that's easily overlooked and that's cleaning the top of the block in between courses and this is a very critical element because it's easy to get a small rock and a small rock in between the blocks you may not think of it as much but it can throw the level of the next course off and all of the subsequent courses afterwards and it's very easy to get rock in on a geogrid layer because that geo grid when we lay that down can actually trap the rocks in between the fabric in between the blocks and you'll see zach very carefully and meticulously sweeping off those blocks
