OK, so I'm sure there are a million reasons NOT to get involved with ferro-cement. It probably hurts the environment, facilitates child sweat shops, kills baby seals or some such thing. And I'm just as sure that there are a million reasons NOT to use it in AP systems however, I'm addicted!! We've been building grow bins from ferro-cement and are about to start on our 400 gal fish tank and its sooo simple, it just makes me think about what else I could build with it. I already have plans to build a small hut that I will use as my office. There are just a million things I could do. Another thing I want to build is a water catchment system.
Soooo, I'm telling you, DON'T buy the first bag of portland cement, or pick up the first trowel unless you want to start down the dark lonely road!
