My driveway meets the foundation on one side of my house and the inspector said it appears a very little amount of water is getting into the basement at that area. The seam has been caulked or siliconed at some point in the past but that is in bad shape and most has come out. I plan on pulling out all the old filler and redoing it. Whats the best product to put back in that space to prevent water from entering? Thanks!
