I don't know if this is the appropriate forum to post this, but here goes: I had a big plumbing problem in my master bath where 1/3 of the shower water flowed down behind an interior wall from the valve when we took a shower. We hadn't noticed it (since we were in the shower when it was running down the interior wall) for maybe at least 6 months. The water saturated our osb subfloor, the hydronics and gypcrete above it. Underneath the subfloor, we were very energy efficient and had soy foam closed cell insulation and it happened to completely contain the water within the osb subfloor and the TJI joists above it. Not a drop leaked out onto the dirt area below it. Does anyone have any experience with saturating of either OSB subfloor or TJI's for extended periods of time? The mold and water damage guys are currently drying out the wet area and so far it has taken over 3 weeks of heating (we live in a dry climate near lake tahoe) and drying for the water content of all the wood pieces involved to get below 60%. There doesn't appear to be any rot per se, but I was wondering if the TJI's would lose any of their structural integrity through prolonged exposure to the saturated conditions? The OSB subfloor is a bit spongy, even though it is dried and since we have dismantled our house this far, we will probably just replace the subfloor, just on principle. Any recommendations? The local engineers don't seem to have a clue what any rule of thumb is for dealing with a situation like this. I have a call into the APA and the TJI people to see what they say, but so far no one has called me back.
