Well, visually not much happened this weekend, but functionally it was huge. I figured out the water problem. We had noticed water (a couple weeks ago now) in the area noted by the large blue oval, so i removed a single Dricore panel in the theater area against the wall, and i gutted the flooring in the craft room closet. It's been dry for the past few weeks, but then it rained all day Saturday. Didn't see any water in the basement, but i did go outside along that wall to check for issues while it was raining hard. I figured out that the gutter along that wall was clogged, and all the water from that quarter of the roof was basically overflowing at 1 point right next to the foundation, where i put the small blue oval. The water must've been coming from that and following the blue path i drew. To temporarily fix it, i placed a 4' x 4' piece of OSB and leaned it against the wall right where the gutter's waterfall was, so at least the water would be directed out ~2'.
Then on Sunday, i got up on the roof and cleaned out the entire gutter, flushed it all out, and i highly doubt we'll have an issue again. Most of the issue was a giant holly tree we have at that corner of the house, so i chopped the top of it off so none of it is above the roof at all. I do still have to put some dirt around the foundation in that area to create a proper grade away from the house.
So we'll leave the craft closet without a floor for a little while, to ensure we don't see water again, but when we feel comfortable, we'll buy 8 new Dricore squares and put flooring in (luckily we have enough extra of the laminate).
Only other thing i did this weekend was borrow my co-worker's router and round off the edge of the riser to protect the carpet that will eventually be wrapped around the lip.
