How to finish a brick interior wall against the ceiling?

[mlitsgard]

I am going to partition the laundry room in the basement to build a bathroom. The floor and ceiling are concrete. I was thinking of building the wall with lecablock, but how do I attach it to the ceiling? It seems tricky to put mortar on top of the last row, a centimeter under the ceiling.

Non-load-bearing partition wall? Such walls should not bear any loads from the joist above and therefore end a few centimeters below the joist. The gap is suitably filled with foam or mineral wool. In your case, the former.

OK, thanks! I suspected that it might be that the wall couldn't be load-bearing, but I wondered what the standard solution was. Foam, then!

Sheep and sheep, it doesn't really matter, it's just more work if you need to make it load-bearing.

But you can still build all the way up, it won't become load-bearing just because it goes all the way up, right? Can't you add more mortar in the joint under the last layer of stone so you reach all the way up to the ceiling?

I don't want it to be load-bearing, I just want it to be stable enough to tile on without it cracking. My question was how to seal against the ceiling so that it is suitable for a wet room wall. I can adjust the distance to the ceiling, I have to cut the stones for the last row anyway. I was wondering if the wall needs to be attached to the ceiling to avoid movement at the joint, but that might not be possible without making it load-bearing.
