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

This building is a surcharge on the soil. This surcharge must be taken into account when calculating the retaining structure. Whether and how this was done cannot be seen. However, it should be allowed to point this out. Have a nice evening. I'm out now.
