I hope someone can offer me some insight about a dry stack wall (if I am using the right term). I have attended courses for SRW installation so I understand and have built some, mostly the garden type, not retaining much of anything. I have a family member that would like to have a garden wall built from palatalized flagstone? wall stone? whatever each of you may call it. It will only be about 6"-8" high at the deepest end and then blend into the existing landscaping because of the slopes. My questions are: Would the base be similar for a small garden wall built from SRW blocks such as Garden Accent from Allan block? Which from what I have learned is 4-6" of crusher run. I also understand Allan Block uses more of an #57 type stone on retaining walls. I assume that you would want a similar base because I do not want the stones to shift too much over time. Again going from some of the SRW ,would it help to have some drain type stone such as #57's behind the wall so the soil doesn't push out against it? Or is this all overkill for this type of project? As the wall starts to hit the slope I would plan on stepping up the base such as in SRW after you bury one block. Any opinions? Thanks for taking the time to read my thread and any basic insight is greatly appreciated.
