How does a concrete bag wall hold up?

by Bbunny42

Looking for input from persons who have built or who know someone who has built a concrete bag wall as to how it holds up over time. Does it crumble or shift? I know you can put in rebar rods to stabilize it; do you need to do this if your wall is only two or three bags high? Thank you!

    Yes I would stabilize with some kind of vertical support. Two or three courses high does not provide a lot of weight to counteract horizontal forces.

      I just need it to divert water to the street when it rains and 3 bags high is an estimate, but I'm hoping that will work. May take more.
