I built a 12'x20' shed foundation on the Oregon coast last Summer. It is 3/4" pressure-treated Doug Fir plywood over P-T framing. The plywood was very wet when purchased and installed wet like most PT woods. I still plan on installing a lino or laminate floor over the plywood once finished. I plan on erecting walls when I return in the Spring. A neighbor told me that water has now leaked under the 10 mil Visqueen cover and is puddling in places. The sheets are screwed 6" O/C in addition to construction adhesive at all framing members. Will this standing water damage the plywood very much if I don't re- wrap it before spring or am I OK?
