Hypertufa for ponds.
A few days ago someone posted about hypertufa for mushrooms and it got me wondering about whether it's a suitable material for a pond.
The truly tiny yard has a shady corner that is crying out for a little pond and waterfall but all the ready made pond liners are too big and the cascade waterfalls are too high - combination/self contained units just don't do it for me (except one that I say at a mere £6000)
I have some pieces of granite - not enough for a proper rockery but too much to just discard and I'd quite like to build something that looks like it might be a natural outcrop with the wall built over it (planting to hide the join) with a spring flowing over into a shallow pool that then looks as if it's disappearing back underground.

The borders in the yard are about 12 inches wide and I don't want the pond to extend much beyond that and for the single fall waterfall to be no more than 18-24 inches.
So.... I have he stone to dress the mound, which I'd waterproof with a piece of pond liner, but would hypertufa make a good pond?
I don't want to have fish in it, and being enclosed by brick walls I'm not expecting to attract frogs etc but I'd like something that would attract insects for the birds and that has shallow areas to act as a birdbath.

I found the image below that is something like what I have in my mind's eye, and about the right size if you imagine the pieces of rock to be not much more than 2-3 inches. (The image is of a "pondless" waterfall over a retaining wall)

Or is the whole hypertufa idea daft!? And should I just go with a piece of butyl liner?




Don't know whether the pH would be too high in the water to encourage any wildlife or grow any plants. Also, im not too sure if hypertufa is the same as the normal tufa but it is incredibly porous !!!

Whilst the pH of the hypertufa would be on the high side this would not matter if you were not having fish etc in the pond. I have never thought of this medium for pond building but it could be interesting. I would use the liner regardless and then either make fist-sized pieces of hypertufa as rocks or mould the material over the liner to make the full pond. Could look good once it has started growing moss etc.

realised that I'm passing a water garden specialist later today I think I'll call in and look for inspiration/advice. Moulding over the liner could be the answer as that could give me a bog area as well. Also thought about having to provide a reservoir under, but not wanting a 'conventional' pebble pool as the smallest seem to be 2ft diameter.
