Biological Concrete
Biological Concrete
(OP)
I'm a little skeptical about this.

The concrete mix apparently uses a low ph (around 8) which is slightly acidic...thus potential for rusting in any attached or embedded ferrous material.
They also use a three layer system (structural concrete, then a membrane, then the "biological concrete" that absorbs and traps water for the little groweys.
What about freeze thaw in colder climates?

RE: Biological Concrete
However, if you used fiberglass or stainless steel rebar/embeds then perhaps this could work. I'd actually love to try it out.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
