Just keep in mind, regular concrete mixes don't work to well. The aggregates they put in them are too large , which create voids in the forms. Whereas Quikwall pours and spreads like a liquid, and is fiber reinforced.Interesting idea, coolkeith. I think I may try a fiberglass and cement combination, sealed with clear epoxy. I'll have to see what's available locally this week.
Woah... I don't want to pay $200+ just for a sealer... Is there anything else out there? I can't seem to find it anywhere other than ebay...Max ACR Epoxy Resin is what I've been using. It's made specifically for "Aquarium Construction" and doesn't stink bad when it's curing like most epoxy resins.
