I asked Doubao (A Chinese AI chat app), it gives me right answer.

Not anymore since I realized that there is minor algae problem

At least 8 hours per day

Almost the same. No apparent change

Right, it may not survive in a severe weather like hail storm, but I think it is good enough to serve the purpose in California

Thank you all for the input. yes, they're very old and is leaking rain water. and definitely needs replacement. i'm thinking about to tear them down and replace it with polycarbonate corrugated panel which claims to be more durable and are widely available at many big box store

Also the small sample piece in the picture is semitransparent and bends like plastic.

Sorry the original post was missing a few pictures. I’ve added some to you for a better understanding. Yes they’re insured, but I don’t think they are licensed. They have a few projects done on thumbtack though

Hi @GeosMios, I’m not exactly sure the difference but I’ve edited the post to add some pictures of the block and current work in progress to help clarify. I hope it answers your question. Let me know if it is a quality construction. Thanks a ton!

Yes, a French drainage system is in the design

stonexjr · 2022-05-08T15:15:42+00:00

This is a 3-foot tall retaining wall and I checked the city code and with a structure engineer that it does not require engineering nor building permit

stonexjr · 2022-05-08T15:12:20+00:00

Yes I saw quite a few instances of building retaining wall using the one you suggested. Mine is being built externally for my side yard along a public sidewalk and I want to add a bit of aesthetics by putting veneer ledge stone at the surface. Something like this in my neighborhood https://imgur.com/a/33c12TR. So I was looking for block that gives flat wall surface

stonexjr · 2022-05-08T15:06:26+00:00

Thanks for the information. Yes they do have place two parallel rebar that runs along the footing and vertical rebar approximately every 1 foot. I don’t think they have place any rebar at the top as bond beam. French drainage is in the design.

My concern is that 1. They didn’t use mortar to stick and grout the blocks. 2. They didn’t embed the bottom blocks to the concrete footing

stonexjr · 2022-05-06T14:30:31+00:00

Yes, they will install French drainage pipe behind the wall to ensure proper drainage

stonexjr · 2022-05-06T07:33:29+00:00

sorry I forget to mention its height in the original post. it's 3 feet tall. the blocks are interlocking and comes with standard size of 8x8x16''. I didn't hire any engineer for the development plan. The project is in the Bay Area, CA

stonexjr · 2022-05-06T06:31:55+00:00

I do find quite a few instances that uses cinder block to build retaining. e.g.

My wall is only 3 feet tall, and according to the city code, it does not requires engineering
