Almost all human beings have lost contact with the natural world. Idiots invade animal’s space, and then many will be injured or killed by that animal. They need space particularly when having new borns. Man in Alaska stomped to death by a moose, while trying to see her new born calves. Human stupidity!

Unfortunately replacing your drain tiles, and new waterproofing is the best option. Patching, or waterproofing from the inside allows hydraulic pressure to dislodge the coatings. Whereas on the outside the pressure pushes the waterproofing against footers, or walls. Somewhere I have seen a inside perimeter drain tile. Mounts up against the floor wall corner. Have no idea if it would work. I sympathize. Wish you the best of luck.
