A Short primer on Hypertufa.
I think it is time to talk about hypertufa!
You have probably seen those big planters and troughs in
pictures of old English gardens. They are most likely made of
Tufa rock. You can learn all you need to know about this and get
an interesting geology lesson at the same time if you click this

A source I always reccomend for instructions and outstanding
ideas is http://www.rlstore.com/ Hyprtufa is fake Tufa stone.
You can read the article about mixes to find out how to make it.
It is fun to play with. You can shape it, file it, form it, add
to it the next day as long as you do not let it dry out. (just
cover with a piece of plastic) It can withstand the coldest
winters and loves the rain. The longer you have it the more
character it gains.
If you want to make something big, this is the stuff to use.
It is not waterproof so no ponds. You can try to seal it but
would be better off to use concrete. It would be cheaper and far
less aggravation.
You can use it for fountains that do not have to hold water.
What I mean is that the water will not be sitting in, just
passing through.
It is relatively light compared to concrete so makes great
trough style planters. If you have ever wanted to make a "Giant
Head" statue it is great for this because you can take your time
molding and add to it as you see your statue taking shape. If
you do not like what you see, it is easy to knock off a bit and
change it. When you are done it will, unless it is 3 or 4 feet
high, be possible to move it without a forklift or crane.
Like the natural Tufa, it supports the growth of Moss and
Lichen. This gives it an aged look in one growing season.
Once you get started with this you will be hooked. It is great
for use in molds, you mix as usual and press it into the mold.
In a couple of days, when it is cured, you can take it out and
you will have a light, textured looking casting. These are nice
when lightly stained, or given the moss growth formula.
Mix up a batch and try it!
