Acting as an Owner/Builder I built a stilt home on a saltwater canal in Florida. I contacted a local manufacturer who put me in touch with a local contractor experienced in erecting sips panel homes. He put up the frame and panels. I subbed the rest.
13 years later we discovered a lot of dry rot in the osb panels used to construct the floor set on a steel I beam system. I had the panels coated with sheet aluminum on the exposed underside as a protective finish.I sealed the joints between panels with "peel & seal".
My concern is how to repair the damaged osb?
bobnrobn
what brand panel were they?
Have you contacted them?
From what you said it appears the sheet aluminum captured moisture with no way for the osb surface to dry out.
Who suggestion was that the manufacturer, architect?
If It was mine I would strip off the osb somehow fasten new osb or plywood screw thru the floor with fasteners of some sort in your location SS with large washers.
Leave the alum off maybe paint it.
