Its leaking badly inside garage under wall into finished room.
Its mostly the garage door rubber seal that lets the water into the garage. I've ordered a new one, but I would also like to seal the wall-floor interface to offer insurance against it leaking into the other room again. I cleaned it out as much as possible, but its not super clean. Im attaching some pictures. Any ideas what I can pour into this area?
If I can find something that I can use while its still damp, that would be great. Its now rainy season.
Arrows where it leaks. X is where garage door contacts floor, where most water gets in.
Unless you change the grade outside of that door, or add some form of grate with a drain there's is no way to "seal" that mess up.
That's been going on for a while, I'd bet if you cut out that sheetrock by now there's wet insulation and black mold in there.
