anybody got any ideas how to do this? I'm hoping to have the rock formations half submerged

Hi yellowboy

Run a search on hypertufa in this forum for answers. There are recipes and how-to's given, but I don't remember which post! I *do* remember, though, that I got pretty excited!!

Hypertufa is a mixture of a concrete aggregate mixed with petemoss and sand. Over time, and exposure to rain, and other elements, the petemoss disintegrates and breaks down. This is not something that I would put in an area that would be constantly beat on by a waterfall. I would recommend constructing the rocks out of a portland cement/sand mix, with a waterproofing sealant named xypex, which you mix in with the cement mix while applying. I am not sure of where this waterall will be situated, but if you do not waterproof the waterfall, water will slowly leak through, damaging any wood that might make up the shell of the enclosure. Just my experiences, good luck...

Even when sealed? Living in the granite capital of North America, I have yet to muck about with making rocks. I just pick up a few slates, scrub them clean, and set them in the terrarium. That said, I think I might start making some of the styrofoam/tile grout rocks for decorating before too long... Too intrigued by what I might be able to make happen with the stuff to leave it alone...

Here's one link:

I just shape the rock structure out of styrofoam and cover it with a couple layers of tile grout. That should work for a waterfall application.

will tile grout effect the pH of the water or otherwise leach any harmful chemicals out?
