I would gladly welcome tips on what to use to fill a 3 cm deep, 5 cm wide hole/crack between the concrete footing and a masonry exterior wall in the basement. I want to minimize air from the outside seeping in and forming condensation indoors.
Don't need a lot, just something convenient that seals tightly and is easy to apply

Quick concrete filling should work well for that.
