My girlfriend and I saw a meme on Instagram of a house surrounded by treadmills titled "How to survive the Zombie apocalypse". After seeing it, my girlfriend said "I don't think this would work; they would all stack on one another", and then she asked me whether "they would stack on one another" is correct, and I couldn't answer her question because I got confused myself, being a non-native speaker. I would've said "they would all stack up on top of each other" but I'm not sure....

Nothing you or your girlfriend said is necessarily wrong, but the most idiomatic way to say it would be the above.
