What happens here

After the initial Class 5 layer is compacted, install subsequent courses of retaining wall blocks. Ensure these layers are also properly glued together with concrete adhesive and leveled. For the main patio area, use pipes of a specific diameter (e.g., 1.5-inch diameter metal pipes) as screeding rails. Place these pipes at the desired height (e.g., 2.5 inches below the top of the blocks) to guide the sand layer thickness. This method ensures a consistent and level sand bed for the pavers.

Goal: Add additional block courses and prepare for the sand leveling layer

one block is down the other block is down and when you do it this way it helps to keep that from happening class five is packed i think we're a little low over here still yeah that's gotta come up about a half inch so what we're doing for the sand so we need two and a half inches down from the top of the block and then we're gonna put our uh put our pipes down there like i said we're about a half inch too low here so we'll have to sprinkle some in there um get the pipes you gotta cut one cut one to fit through here so that then you know we can screed it on either side get that sand nice and level so you don't want too much sand it's easy to go overboard on the sand but really less sand is better because there's no binding agent to it so although it's non-organic and it will stay in place since it doesn't have a binding agent to it mother nature can move it around easy on you okay next bit class five's all leveled got the pipe all level where it needs to be um so yeah it's just sand and we'll get that all leveled out
