Remove interior wall in basement?

[lexus]

Is it possible to remove a partition wall in a basement located under a concrete vault that is 15 cm thick? I mean without compromising the load-bearing capacity of the structure. The partition wall is 1.90 meters and is situated between another interior wall and the exterior wall, with about 1.5 m between both. The partition wall is built of some type of concrete hollow block.

Edit: I can add that there is currently a door in the partition wall.

It probably requires some investigation. It is hardly obvious that it would work.

The house was built in 1957. Does anyone know how they went about things back then when casting concrete vaults? Were all the interior walls built in the basement before pouring? Was the entire floor in the basement poured first or was it done afterwards? If so, would they have first cast a footing under each interior/exterior wall?

My parents were building a house at that time. First, the slab was poured, then the outer and inner walls were built up. Finally, forms and supports were set before casting the floor slab.

Thank you for the answer. It should mean that my basement floor is reinforced and not particularly easy to break up. All the interior walls in the basement should then be part of the load-bearing section together with the outer walls, right?

The wall I am considering removing is only about 10-11 cm thick while the other walls are a little over 20 cm thick. Does this mean that the thin wall is built afterwards and can be easily removed?

To be on the safe side before making any alterations to the construction, contact a building engineer to make an assessment.

Agree!
It's not easy for a layman to see if it's a load-bearing part or not.
It can be load-bearing even if it's been added later.
