Variants of basement construction (Pour concrete walls in the middle?)

Hello everyone,

I am curious about your experiences with the different types of basement construction here:

I will list what I know and what - unless I forget something important - should be the most common?

1) formwork basement walls (metal plates are used to build the formwork and then concrete (e.g. WU concrete) is poured in and cured there)

2) the prefabricated basement (prefabricated basement walls are delivered and placed in their respective positions with a crane)

3) what a friend recommended to me: a type of concrete wall formwork (no metal plates that are removed after the concrete hardens), the interiors of which are then filled with concrete.

Since my friend recommended option 3) (supposed to be one of the most cost-effective), I am primarily interested in 3). What is this type of concrete wall formwork called? Do you have any experience with it?

Is it generally sufficient, if you do not use WU concrete, to properly coat the exterior walls with bitumen (which is then called black tank, right) and then glue the EPS board for insulation onto it? Will this provide lifelong peace of mind and is the basement sufficiently sealed?

What is better for exterior insulation? EPS or XPS boards?

Thank you very much for your inspirations and suggestions.
Ann.

Element walls consist of two prefabricated concrete panels connected by lattice girders. For this reason, they are often referred to as double walls or hollow walls. For the element walls assembled on the construction site, the hollow space is filled with cast-in-place concrete, resulting in a monolithic reinforced concrete wall.

The variant from No. 3) is probably called an element wall in construction jargon. How are the edges / joints of such an element wall well protected against moisture? Is a good layer of bitumen, i.e. a black tank waterproofing, sufficient? That should be enough, and you can stick the perimeter insulation directly onto the bitumen. XPS or EPS?

Does no one here really have an opinion on element walls for basement construction?

Not even on whether to use EPS with drainage stones or only XPS boards as perimeter insulation?

We mostly have this type of concrete walls. Also for the garden walls. However, made of WU concrete with corresponding sealing strips. On top, bitumen, insulation, and double dimpled membrane. Once the foundation with the vertical reinforcements is in place, it goes quite fast. Erect, fix, put in reinforcement, seal, fill, and wait a few days. After that, the props can be removed. In my [TE] you can see a few examples. Walls are super smooth and can be painted immediately with the appropriate paint...

stick the perimeter insulation.

So insulation has nothing to do with barriers. First, one would have to look at the soil report to see if there is pressure water, which already influences the method of execution. The sealing has recently been regulated in DIN 18533. At the moment, we are dealing with too many variables.
Oh, and of course, the masonry cellar still exists.

Does no one here really have an opinion on element walls for basement construction?

Where is the house described in relation to the basement question?
