I have a garage that is on a slab. Yesterday (for the first time in 27
years we have lived there) there was water on the floor about half way
down. The puddle indicated that it came in at ground level and there
appeared to be no discoloration on the wall so I would assume it is
coming in where the slab and the wall meets?

Why not under the garage door? That's where it came in our garage.

Any suggestions on the possible cause and possible corrections?
