Anchoring Leca blocks in concrete slab

[Stickan56]

Then the question is whether the dowel even needs to be cast in place, if he drills an 8mm hole and drives down an 8mm iron, it should be sufficient, right?

It's likely sufficient if it's tight.

Should a wall really lean as much as 10-12 degrees???

What should you do if you want a wall that is vertical? Build it wedge-shaped?

I don't quite understand what you mean by wedge-shaped. A leaning wall has higher stability. By leaning it, you reduce the wedge-shaped mass of earth that wants to fall down and push out your wall. Aesthetically, I don't see any problem with a leaning wall either. The easiest way is to shift each stone course 1 - 1.5 cm inward. The challenge is if the wall has to curve, as the radius at the top and bottom will be different. If you want to build it vertically, L-shaped concrete elements can be used, although not beautiful, or anchor it with inward ties, but it all depends on the height and construction.

Here I am, away from the thread for a week, and there have been so many responses, wonderful!
With wedge-shaped, I assume Vojma means vertical outside, slanted inside.
You are right that the forces are lateral forces, and if you have a tight hole in the plate, the reinforcement bars shouldn't be able to go anywhere. There are no lifting forces, after all, that could pull them out of the holes.
I'll try it on some hole and see how it feels.
I'm not entirely sure what to fill the holes in the Lecablocks with, but I'll probably make some kind of fine concrete from casting sand (0-8) and cement. Do you think that will hold? (I happen to have a bag of cement lying around)
I have planned to reinforce every layer in the wall, even though Weber considers it sufficient with the top and bottom.

In the inner angle between the footer and the wall, you fill up with mortar to a height of about 1.5 stones.

How thick "layers" can you actually make with mortar? Flexoheft M5, as mentioned, has a stated maximum thickness of 8mm.

No, you're right, I mixed up the terms. What I meant to write was 10-12%, which should give 6-7 degrees.

Kind regards, Stickan

It went a bit fast there. If you're going to support from the back, you do it with earth-moist concrete that can be packed, but in your case, you can probably skip that part..
