I was asked this question by my boss. He has tiles that are breaking every 8′ down a school corridor. It is basically a 4′ wainscote with durock backing. The tile is breaking on the seams of the durock. My question is would this be more because of not properly floating it out, or because they may not have the proper 1/8″ gap between the sheets?

Sorry Cal I have been busy. It would be metal studs and I would have to venture a guess at 20 gauge. That seems to be what most are specing around here. The hallway woulkd be at least 100' I would think and maybe more.
I couldnt even venture to say how the durock was applied but after learning who the sub was then have to say that no, they probably didnt use any mesh. I refuse to let this guy on one of my jobs.
The tile is what is breaking mostly except for an occasional joint. I am begining to think it may be due to weak framing. Glad its not my baby
Btw, how do you check for replies on here?

bam,
In your profile you have to check a box or two that say you want to receive email notification of replies to your post.
It will have a link in that email-that as of yet doesn't take you to the post in question. It takes you to the original post in the thread-pity you if the thread is large-then it's hunt and peck till you find it.
If not mesh I would have to guess that stress point without a mudded bridge would be the weak point. Also, the amount of fasteners used on that joint. I would think you would want to layout so the joint fell off the studs, then use a sort of "butt taper" blocking to join the two together. Steel studs are not more than an inch and 1/8th of fastening surface-with durock, not near enough. Hell, I'm not even sure you wouldn't want a backer on the wall, then durock.
There must have been specs on that detail, no?

I'm sure there was a spec but I havent seen the plans to it. I'm not even sure of the Archy who drew it. I am just trying to get some different ideas because I might have to go troubleshoot it and see who is at fault. It would be I would think between the rocker. drywaller or tiler I would think. Knowing the tiler I would say him but I am trying to be unbiased.
the only reason it would be breaking on the butt joints is the panels are not anchored properly, or bad framing. All comercial work round here requires dbl layers of dw, that and alternating the joints would spread the load and stiffen the sheets ..
