Foundation Staining After Storm
Hello all, After some wild wind and rain last week in Midcoast Maine I noticed some staining on the south side of my foundation. There are a few spots elsewhere, but the bulk of it is located on that side. Assembly is vinyl over Zip with a 5/8 rain screen. basement is insulated with closed cell foam up the walls and rim. The rest of the house is Roxul. I can see no inward signs of moisture anywhere in the house. I have also peeled back the siding in a few spots and see no signs of water damage.
Could this be a failure of the zip tape somewhere further up the wall that allowed the water to get in and run down the interior side of the sheathing? looking under the pvc trim you’ll notice that it doesn’t show any signs of mold or rot. It was never sealed to the foundation wall. We have been in here for 2 and a half years and haven’t changed anything recently.
Appreciate any thoughts
