Mold

[strevert]

I am going to build a casting mold for a footing for a wall and have a few quick questions.

* Do I need geotextile between the crushed stone and the footing? (so that the concrete doesn't seep out)

* How thick should a footing for a 2-meter wall be at a minimum?

* The footing's width will be about 60-70 cm, is it enough with reinforcement on the sides or should I go with a mesh?

It didn't quite cover what I had in mind. More about pouring in a ublock.

I am going to cast a foundation for the wall with 20 cm 8-16 macadam. This is at the same level as the house foundation (basement).

I don't want to go deeper due to drainage. So I can't pour in a trench. Instead, I'll rely on a strong foundation that I anchor to the house's foundation.

At the other end, there will be a 90-degree bend with an additional wall. It will be like a counterfort then.

The dimensions will be 3*3 meters at 2m height.

More tips?

You don't need to have a cloth on the macadam.

The question is whether you really should anchor the sole to the house, there is then a (small?) risk that you might tear the house apart if the wall moves in relation to the house.

You say that... hmm. There's a small rock ledge on the opposite side. Maybe anchor there instead.

* The width of the sole will be about 60-70 cm, is it enough with iron on the sides or should I invest in a mat?

I don't understand what you mean?
Iron on the sides? Do you mean in the future wall's longitudinal direction?

Yes, exactly. Longitudinal armeringsjärn

Net at the bottom is usually sufficient, depending somewhat on the loads that will be placed on the foundation sole.

Now I don't have any mesh but 10 and 12 mm iron at home. Then it's enough with 2-3 of those longitudinally on a footing of 3000*600*100 as I understand it.

Yes, exactly. Longitudinal rebar

You should probably have something crosswise as well.
