Hi, our land has several elevation levels. The lowest area is unfortunately very difficult to access with machinery, so everything needs to be transported and installed manually. There is an existing slope about 120cm (47 inches) high made of stable (so it doesn’t slide on its own) but muddy stone/muschelkalk/mud/clay that needs to be retained. Only foot traffic will occur on the plateau, so there will be no additional load from vehicles or similar.
I have ordered steel H-beams, which I will set in concrete. In the recesses of the beams, I plan to insert 10cm x 10cm (4 inches x 4 inches) squared timbers (I have plenty leftover from construction) from above. Against the slope, I will install a dimpled membrane and drainage gravel, and possibly a drainage pipe. I think this will hold.
What I’m unsure about is whether I can stack the untreated timbers directly on top of each other (they can’t be treated now because of the current weather) or if I should use spacers (for example, nuts) to allow some ventilation. Of course, the dimpled membrane must never be damaged, otherwise all the muddy water will flow through. I’m concerned that stacking the timbers directly without ventilation might cause the entire wall to rot.
Best regards

... Well, it would be funny if the "wall" was supposed to hold up the house. I’m not that foolish... The house is supported by a huge separate wall... And on top of that, there are two massive foundations that will carry the supports for the future parking deck. So, THIS wall only holds back the natural slope, which has now been slightly built up.
The dimensions of the H-beams and planks have already been described.

How deep is the separate wall of the neighbor? To eliminate soil pressure, it must extend down to the bottom edge of your shoring. Was the company aware that you would still be excavating there?
I just noticed that you are tying in a 1.8 m (6 ft) high shoring at only 0.7 m (2 ft 4 in). In my opinion, that is not enough.
I wouldn’t be able to sleep well with that.
If you haven’t excavated yet, then everything is fine.
But you need to prove the structural stability of your shoring.

Of course, you could have it all calculated professionally and done according to all the rules of the trade with a warranty, but then you pay many times more. I think it’s great, and it doesn’t seem to be done carelessly or without reason.
I once built something similar myself, though not as high, and it is still standing today, even though I was advised to build a wall with a foundation, etc., costing a lot of money.
If anything does actually give way somewhere, you will see it... so what... then just add a few more posts or supports in those places.
