Hello everyone,
we are in the middle of a house renovation and have now reached the kitchen and bathroom, which are adjacent to each other. We decided to do both parts at the same time because we have a wall in between that needed to be re-framed.
Briefly described how the house is structured to better understand what I need help with. The house is about 9x10m and is built with "load-bearing" walls as a cross through the house. In the 4 rooms on the entry floor, we have a dining room, living room, hall, and kitchen/toilet. In one of the parts, we have both a kitchen and a toilet in the same space. We also have an upper floor and a basement in the house.
In the existing toilet, they previously renovated and at that time sawed off the floor joists to be able to cast a floor. This has caused the wall to sink about 1-2cm, i.e. barely visible. Now when we redo it, we will remove the hall to fit a shower in connection with the toilet. Between the new part and the old toilet is the "load-bearing" wall, which has already sunk, making me a bit puzzled about how to solve this in the best way. In the entire bathroom, I will cast a floor, meaning I have to saw off the joists on the other side of the wall as well. The wall now rests on the concrete floor (the ceiling in the basement) and should not be able to sink more than it already has.
Now to my question: Once I have sawed off the joists, am I forced to replace the "remnants" of the floor joists before I cast my floor? That is, am I required to arrange some type of jack to be able to place a steel beam under the wall instead? I have a hard time imagining that the beam will be exposed to any type of moisture and should not be able to rot and cause odor.
I've done my best to draw this up in paint. Note the image is not to scale
Grateful for answers. Feel free to ask questions if there is anything unclear.
Best regards, Micke
