Pure speculation here but I think those bags breakdown faster on the rip rap mix than standard quick Crete

I think it is a less brittle mix as well

I've seen it used under pedestrian bridges in remote sections of a local state park here in my neck of the woods, it's aged very well over the last 10+ years. I've wondered too if the standard quick Crete would work well around my pond. I'd love to use some at the mouths of my feeder creeks and the little boat landing area we have
