   You might search the archives. Something like this maybe a yr. ago. In that case, the partition walls were sleeved at the joists so they could rise/fall. I think that's the way I would go if that was an option. Believe the original poster/respondent was from Colo. If you can sleeve the top of the wall, it was suggested using a deep throat metal (stud) track fastened to blocking at the joists. If you can't, flashing that shower should be a real treat. Gotta be someone that has that figured out by now. Best of luck.

   *Tom,I may have been that poster from Colorado. In my basement I floated the walls this way: Shot a treated sole plate to concrete floor, built walls 1'1/2" shorter that plate to joist measurement, used scrap 2x material to hold wall in place between treated plate and wall plate and nailed to joists. If the slab rised only the treated plates move. Just don't attach your drywall to that treated plate. Your baseboard trim nails will just bend if the floor moves. Use spikes to hold wall to treated plate through pre-drilled holes. Hope this helpls.Cole

   *Tom....Seems like the code creates the problem that has to be solved...Why not pour monolithic slabs and be done with such goofyness. I would think if the slab were placed on stone, all would do well.not near betonite...in my stream,ajIt does sound like mounting all to the floor is the practical way to go too.

   *Tom I've framed a few basements in bentonite country.As far as the I Joists go if your wall is perpindicular to joists you're OK to just nail through top plate and into the joists. When your walls are parallel what I do is make a wall tie out of two blocks of wood. One is cut to fit snug between plywood webs and the other is cut snug between bottom chords of two joists. I nail them together so that the longer one hangs off each end of the shorte eequally. Two or three nails does the trick. Then tuck the block assembly, long block up, into the joist bay and nail it to the web so it is flush to the bottom of the joist. As far as the shower goes do the archive thing. Calvin's right it's in there. The way I do them is there. It's a little to involved for a sleepless guy to go into.good luckjim

   The bentonite soil in this region is highly expansive. Code requires that basement slabs be independent of the foundation walls so they can rise or fall without damaging the house. Partition walls must be suspended from the floor joists and have at least 1 1/2 inch clearance over the slab. My questions are (1) Is any special technique required if the floor joists are wood I joists? I'm concerned about the possibility of pulling off the lower flange. (2) What is the best way to put a shower in? It seems like the pan, enclosure, and plumbing have to go with the slab... but other walls are suspended from above!? Any pearls of wisdom out there? Many thanks.
