Gap between driveway and foundation wall
I want to "seal" this gap to prevent water from draining into the ground right next to the foundation wall. I have tried driveway gap sealer and blackjack caulk and both cracked over time.
Now I am thinking about aluminum flashing. I plan to paint it black and seal one edge to the driveway with blackjack caulk (elastomeric). I will let the opposite edge just sit up against the foundation wall. As the driveway heaves, the aluminum flashing should just slide up and down the wall. Picture the flashing being bent into quarter cylinder shape with one side being caulked to the driveway. This should catch any rain dripping off the siding of the house and should block any water that puddles on the low spots of the driveway from emptying into that gap. One challenging issue is that I have an inside corner to deal with. The front of my garage sits back about 10 feet from the front of the house so there is an inside corner where the front of the garage meets the side of the house.
Any other suggestions?
