It would probably need a fair bit of water, too, unless you’re in a more humid climate with summer rains. It is a grass after all.
Unless you planted a tropical clumper, the concrete wouldn’t take damage. A runner would probably pass under it and show up on the other side eventually though. You can stop that by cutting the rhizomes back in summer and fall (think of it like edging a lawn), but it sounds like that space might be too narrow to set that sort of system up well.
