I believe to hold water is one thing, great, but using epoxy and polyurethane, what will you do with the polluted water afterwards? What is it’s purpose? I have also made this same combination of materials and found it was not healthy. I used these materials for making a foundation for a living sculpture, housing many plants. Held water, sure but how would this effect the health of the plants, I wonder? Have you ever smelt epoxy? These are hazardous materials in my opinion, unsafe and not green savvy.

Want to go green? think post (GRD) great republican depression, Think post psychotic consumerism, Think post Obama era, Think Americans humbled into shanty-towns, living in 10 x10 cardboard and scrap metal shacks, working part-time, occasional jobs when catch can, walking and cycling out of necessity, living on near meat free diets of mostly composted and humanured veggies from hand turned garden patches, wearing rags over rags, handcrafting windmills to power old laptops and transistor radios, scavenging old dumps and scrapyards for material. Impossible? take a good long hard look at the photos of the now defunct U.S.S.R. on this very web! Betcha they thought so too! The common denominator? Sustainability!
