Proper instalation for a cinder block retaining wall
I am going to be putting up 2 cinder block retaining walls in my back yard(hopefully this weekend) and wanted to get some advise on what is needed.
I know that for major load bearing applications and to make it bulletproof, it would need a concrete footer with re-bar set in it, the blocks assembled and filled with concrete.
For this application, each wall is going to be holding 20inches of earth(24" of block, with bottom row 4" below grade). This will be a stepped set up with the second wall sitting back a couple feet from the first.
This area does not see very much run off but is in Denver, CO(so it does see snow) and the ground is very clay like.
We were planning on tamping the ground beneath the wall, driving re-bar every couple blocks, and filling them with dirt and small rocks(pea gravel).
Am I mistaken on what we need for this?
Any help is greatly appreciated.
Thanks
