Retaining wall kinds
I have a 44' by 2'1/2" retaining wall that is starting to lean. It was built with 4x4 posts every 5' and the planks are 2" x 8".
I am just wondering what are the merits and problems with different kinds of retaining walls:
- retaining wall made by stacked 6" x 6" timber, anchored in ground with 4' rebar, and secured with deadman anchors (no 4"x4" posts)
- brick with mortar
- timber with posts, similar to what this wall was before, but maybe thicker planks
Are posts absolutely needed or would the deadman anchors perform the same job?
Any thoughts welcome!
