"floating" basement walls?
Hi. In Colorado, because of our expansive soils, builders "float" basement walls by having two base plates with a gap between the two. They are held apart by large spikes, about 1/2" in diameter.

I'm getting ready to finish my basement and would like to know if the "float" could be accomplished with 2 top plates instead? I would like to do this to put the weight of the walls on the basement floor, rather than the joists overhead.

Thanks for any info that you could provide.

I'm not an expert, but I think you would be better off having the expansion at the top. I somehow think I remember seeing an episode of "this old house" where they did put it at the top, but I think it had something to do with settling.

floating walls
hi, i know this thread is "old", but i too live in CO and need to build "floating" walls. I would like to ask for more details as to how to build a "floating" wall vs. a standard frame wall. Do not have any obvious problems with moisture, cracking, et al, so is this necessary? also, basement is under a modular (trailer) steel frame with 9' walls and would like help with ceiling options.
i am not an expert carpenter, but will usually get things figured out. thanks!
