Retaining wall: piled-up earth settles slightly

Hello,

a retaining wall was built in our garden 4 years ago. Constructed in the right area.

It starts on the left with a height of 20 cm and is a maximum of 1.40 m high in the corner, but only for a short section of 2.5 meters. After that, the wall continues at a 90-degree angle and is only 20-60 cm high.
Drainage is present. Concrete with steel was used.

The wall has remained just as straight after 4 years as at the beginning and there are no cracks or anything else.

Of course, proper soil was filled up in the corner 4 years ago. Over the last 4 years, especially in the corner, the soil has settled a bit. Is this due to the filling and the soil settling particularly in the highest filled areas?

Just add some soil and reset the mowing edge?

Thanks in advance!

Just looked at some old pictures again. My suspicion is that it was not properly compacted here?

I'm not sure, but I think it was first filled with gravel by the wall, then with soil. I suspect that it should have been compacted in between during the filling? I think that was not done.

My plan now would be to level everything with some soil, reset the lawn edging stones, and be done. Is that okay?

I would do it that way too. Provided the wall is still standing as it was in the beginning. Settling of fillings is normal, at least if it was not compacted. Don’t forget to compact the leveled filling. You didn’t possibly fill the formwork blocks only with gravel, did you?

I would do it the same way. Provided the wall is still standing as it was at the beginning. Settling of backfill is normal, at least if it wasn’t compacted.

Thanks.

The wall obviously has no cracks.

According to the spirit level, it is also straight.

If it had moved, I would have had to see that especially at the corner where it turns 90 degrees, through cracks, right?
It is also completely intact here after 4 winters.

Or how would I notice that it no longer stands as it did in the beginning?
After the 90-degree angle, the wall continues for another 14 meters. Everything here is also without cracks or anything else. It has not sunk either.

Don't forget to compact the leveled backfill.+

You didn't just backfill the formwork blocks with gravel, did you?

You mean the content of the formwork blocks? No, they are filled with concrete and reinforcement

You didn’t fill the shuttering blocks with just gravel, did you?

Does your "thumbs up" mean you agree? If the wall had shifted, settled, or whatever, I should have seen this through cracks, right? At the latest at the corner where the wall turns 90 degrees, cracks should have appeared? Or can such a long wall (8 meters plus 14 meters after the corner) settle/shift without cracks?!
