Long time lurker on this thread. First project post here. SoCal. There’s a 6-8” base. I think I’m enter the point of no return before I start filling in gravel, sloping the drainage pipe. It’s a 4’ wall. First course will be covered up to 7-5”. I planned to set geogrid at 3 and 5 course. I followed the manufacturer guidelines, to best of my knowledge, for the curve. Happy to hear any suggestions.
And I stood on a mountain of dirt I dug out over the last month. From following this sub, that’s a good sign.

Also a lurker, from what I’ve seen this is the best homemade one yet.

He explains everything in there and also builds other cool stuff too
Thats a fine looking wall.
You probably already know this but make sure your fill gravel is clean stone. I see blend under the pipe.
4′ requires engineering design and plan approval, just FYI. My understanding of Cal regulations is that anything over 3′ of lateral pressure, measured from the footing base, requires design/approval. Being in southern california, there are additional seismic design considerations.
I’m not familiar with these specific blocks, but they don’t look like SRW interlocking from the back (it looks like it’s flush on the front and the back) – so they need cell grouting where the attachment rebar come out of the footing. If they are a standard CMU-type block that doesn’t have the interlocking portion on the back, they need a concrete footing with both horizontal and vertical rebar. If you can give me the item name/number I’m happy to check for you.
If you don’t want to go through plan approval, do a 2-tier stepped wall with 2 2.5′ to 3′ walls instead of one 4′ wall.
Just wondering why the drainage pipe goes into the wall?
Looks nice! Can you share what blocks you’re using?
Approved
Finally a wall which won’t be punched down by uphill water weight! Congrats!
Going to want to use clean stone behind it, NOT that stone used for base below the drain pipe!
Good job. Clear crush, drain pipe and a solid base. I love it.
where i am provided you do the proper drainage behind the wall and fill with clean gravel, no need for geogrid unless its over 4′.
it looks good to me boss.
The way you describe it, and the fact you’re throwing two layers of geogrid down on a wall less than five feet, makes me want to have you on our crew.
Make sure to keep it pointed in the right direction
Edit: literally looking at the well daylighted drainage wrapped and the soil covered as I freaking wrote that.
Great job, dude, one of the best diy on the sub all day.
Looks like some dude is under the fabric trying to steal your level
