We just got our house about 2 months ago. I Have a faucet in my garage, which has a poured concrete floor, adjacent to a poured concrete wall that is an interior wall in my basement. We were just shutting off the water and clearing out the pipes for winter, when we noted that the water that fell on the floor of the garage appeared to leak down into the basement. You can see the picture of the damp spot in the basement insulation. I've cut open the insulation to let it dry and will tuck tape it afterwards. What product would you recommend to seal the edge of the garage floor to keep this from happening in the future?
