I'm planning a small landscape wall to alter the drainage around my house. It will be ~3 ft tall tapering to 2 ft over a span of 11 ft before ending.
I plan to use the stone pictured in the attachment.
How many inches do I need to excavate behind the wall? I plan to back-fill with large gravel (#57 stone). If I use #57 stone, do I really need a drain pipe as well? I plan to protect the backfill with landscaping cloth.
In your opinion, is it worthwhile to fill the voids in the block with gravel? Will it make the wall more sturdy?
Thank you!
