Hello,

I am planning to lay new flooring on an entire floor of the house. The problem is that we have removed some walls and doors, which has resulted in 10-15 cm wide "holes" in the floor where walls or doors used to be.

Since it's very uneven in the holes, it won't be possible to fill with something like a wooden batten. What can I do?

There is currently a wooden floor; it’s a wooden joist structure with sawdust underneath. This is one floor up, which means there is a basement underneath.

Self-leveling compound? It feels like it could run out a lot, or is it possible to mix it as a thicker mass? On top, we are planning to lay a 15 mm engineered hardwood floor (I think that's what it's called).

Attached is a picture of the problem.

Thanks!!

No one who has encountered the same problem and found a solution?
 
When I helped a friend who was going to lay new flooring and tore down walls, we ended up tearing everything out to the joists and laying new fresh chipboard flooring... it was an extremely uneven floor from the beginning though, with glued plastic mats and hardboard sheets, which made it less time-consuming to tear everything out. The result turned out perfect, though. If you place a steel ball on that floor, it stays still.

I did the same, also took the opportunity to add to the joists as they were bent in the middle of the rooms. New floorboards on then the floor installation became child's play. Trying to lay new flooring on the old planks carries great risks of the new floor being uneven and creaking. If your floor is completely straight and nice, it might work fine anyway.

In any case, you can actually use regular concrete to fill in the holes. The concrete is quite viscous and doesn’t flow away.
 
Agree with the previous, put down new golvspånskivor.
