OSB exposed to much rain

[enginerding]

Everyone was very helpful with my last question, so I am going to try again!

Does anyone have any guidance on criteria for acceptance of OSB subfloor that has been exposed to a lot of rain in construction? Some areas look better than others. There are some areas where significant delamination is evident and others that look like brand new. It is the range in between that I am looking for some guidance on. Any ideas?

If this floor is a critical diaphragm in your engineering design, I would not allow any delamination. If not, what finish products are going to be placed over it and how will the delamination and/or unevenness affect the acceptablilty of final product by your client? - your call here.

The contractor should have known that OSB needs to be protected to retain it's strength. Let him learn by buying some twice. Don't try to be Mr. Nice guy by accepting a bad product. Protect the interests of your client first. You are his professional representative. If you were the client, what results would you expect to pay for?

Coming at it from a bit of a different perspective - keep in mind that Wet OSB + Moisture = Prime Breeding Ground For Mold & Mildew.

Should have previewed - the "Wet" was redundant.

Agreed--reject it!

Get the APA folks involved. They have guidelines for this sort of thing.
