water is always present in the concrete. if you were to chisel in the retaining wall, you would find rusty rebar.

Should you inject some substance into the crack? I heard that the most suitable approach is to open it with an angle grinder, then blow it clean with compressed air, and seal with silicone. The final part should be plastered with thin concrete.
Who knows anything about that?

it's not a construction casting for Pete's sake. you don't need to fix it.

L-elements are terribly stable. but they also have a lifespan as they endure weather and wind. much more than a slab.
that crack is not a problem. otherwise, just repair the crack. make the crack larger (not much larger 2-3cm deep and 3-4 wide)
patch it with repair mortar or concrete filler.

Yep. But he wants to fix it.
As mentioned, it's unnecessary, the concrete seals itself quite well. It bleeds out of the crack's walls and fills up. If you still want to seal, you can try to fill the crack with water glass or epoxy. You may first need to drill small holes along the crack and press in through these with a syringe.
