RE: Correcting out of level wood frame structures

[Subject Prev][Subject Next][Thread Prev][Thread Next]
If floor levelness is the main issue, have you considered stripping the floor finish, applying a leveling compound, and reinstalling the floor finish?  If capacity exists to support the extra weight, this seems much simpler than selectively realigning the structure.  It would be intrusive, which could be a problem for an occupied structure, but it doesn't sound any more intrusive than having jacks forcing floors around.  If everything is leaning, but not necessarily all in the same direction, it seems like it would be very difficult to jack things back into the place.  If you move one portion one way, couldn't that make an adjacent area leaning the other way get even worse? Also, there seems to be a high potential to permanently damage the structure by jacking it.  Since it was built that way, you are using force to move it out of the alignment it was nailed together with.  The case where an already damaged post-seismic structure is all leaning a few inches in the same direction sounds very different.  Maybe I'm missing something.

Ben,
 
Thanks for the reply. To embellish on my earlier post, additional issues with this structure are that it is a newly completed large finished luxury one family home comprising two levels only with attic and is occupied. The entire building is not racked - individual walls are not plumb.  The problem arose from original construction, not later loading. The bigger issue is the lack of a level walking surface. The jacking procedure which was recommended was intended to permanently deform the joists/beams so as to present a level walking surface. My own impression is that it might ultimately be cheaper to demolish and rebuild.
 
Would that alter your recommendation? If not, what is the time you would envision for the problem to be corrected?
