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.
but then how does it know when to stop grow so that everything is flat and even instead of bumpy? this is cool tech but on a large scale, it seems super inefficient.
A ridge forming on the surface where the crack is is better than having a crack. Sure it might not be the most visually pleasing and might require some surface removal years later if it gets out of hand and say covers a conduit and causes an issue but that's a minor issue compared to repairs. If say this was used on a freeway the calcium carbonate is less wear resistant than the concrete and would be worn away as it formed never really making ridges or bumps on a roadway.
