Something new I really do not like. Putting tyvek on back wards on the “inside” of the foundation wall. Have 30 yrs with work boots on, and this seems just wrong!This is a new house with really good drainage…done right. Location is northern British Columbia, I`d call it a cold dry cilmate, compared to our coast. Seems to me if any moisture did come in it`s going just pool at the bottom and run in. The best place for tyvek is the store, just leave it there. Tar paper good.
I`am just 1 of the worker bees, I do,….. not decide.
