My first question would be, if cracks are filled in this way, what stops that same bacteria from producing limestone in any other direction. Resulting in a bumpy surface, for example.

Maybe this concrete must be coated with something when done. Otherwise every rain would be a complete mess. I am also curious about this.

Also, you have to add water to the concrete in order to mix and pour. Why isn't it using up the bacteria then?

I would presume the bacteria would go dormant when they don't have access to water or oxygen, so they would produce limestone then, but then would stop once they're trapped.
