[@rivaan]I don't think barriers work like that there's nothing to suggest in the Mass effect universe that a barrier created with biotics could actually stop something like a husk or anything of that size from traversing through it - the only thing we see is it stopping the swarms on the collector ship, but not abominations and husks that periodically come through it.
You'd have to create a large stasis field instead - which would be far more difficult and stressful to keep up.

A biotic barrier, based on what I've read on them doesn't allow small objects with varying force from getting through them, bullets or seeker swarms for instance, they damage the barrier lowering its effectiveness till it breaks hence why biotics erect their own barriers in the ME universe as personal shields - it would slow the horde a bit if you were to erect one, but not stop.
