Hi everyone!
I’m getting a bit desperate...
I need to create a slope towards the neighbor’s plot, from street level 0mm (0 inches) up to the end of the terrace at 120mm (5 inches). I’m digging here with a pickaxe, and the soil is stone mixed with clay.
I’m already quite deep below the natural ground level. Do I still need to dig down 80cm (31 inches) for frost protection?
Ideally, I would like to do some excavation, then set vertical reinforcement in concrete, and start building the wall.

Hello M4rvin
120mm (4.7 inches) or 120cm (47 inches)?
Do you need to support the slope on the left?
Is what you see in the pictures the excavation?
Even if you ignore the frost line, what will resist the pressure from the soil on the left?
You can’t embed reinforcement bars directly into clay soil. They would rust away.
Think of it like bodybuilding: dig 80cm (31 inches) deep. I would even consider widening the foundation to the right in the shape of an L (like L-shaped blocks). If in a year or two the support shifts to the right, you’ll have to start all over again.

Oh dear, I meant 120cm (47 inches)!
You can’t really see it well in the pictures, only the piles I’ve already cleared away...
The excavation isn’t fully done yet; right now, I’m trying to level everything out a bit.
The slope is stable on its own; it’s actually like a wall! (Because of the rock vein)
Excavating 80cm (31 inches) is really impossible—I’d need 40 weekends for that!
There will be a garden shed next to the wall. Could I “connect” the foundations?

Is the wall going to be backfilled with soil on only one side? Then you need to dig at least 80 cm (31 inches) deep to make sure it’s frost-proof. Alternatively, you can take the risk and rebuild the wall in X years. How many meters (feet) long will the wall be? Rent a mini excavator for a day. It’s not very expensive.
Exactly, I will backfill on the neighbor’s side afterward. However, it’s possible that they might also make some changes to the terrain once they start building their house.
So, 80 cm (31.5 inches) deep from the top edge of the planned surface? (It will be paved, about 50 cm (20 inches) has already been excavated and filled with lean concrete, but not at the boundary where the wall is supposed to stand.)
There is a bit limited space for an excavator because the heat pump, stones for the terrace wall, and the packaged garden shed are located there.
The wall will initially be about 8 m (26 feet) long, as at 8 m I will be at approximately 40 cm (16 inches) height. The boundary length is about 16 m (52 feet).
The height steps are approximately:
1.2 m (47 inches) at the start
1.0 m (39 inches) after 2 m (6.5 feet)
0.9 m (35 inches) after 4 m (13 feet)
0.6 m (24 inches) after 6 m (20 feet)
0.4 m (16 inches) after 8 m (26 feet)

Using an excavator takes one weekend and costs 150 euros.
