Hypertufa

Picture
Hypertufa is an anthropic (man-made) rock made from various aggregates bonded together using Portland cement.

Hypertufa is intended as a manufactured substitute for natural tufa, which is a slowly precipitated limestone rock; being very porous, it is favorable for plant growth.

Hypertufa is popular for making garden ornaments, pots and land forms. Hypertufa is relatively light compared with terracotta or traditional concrete and can withstand harsh winters, at least down to −30 °C (−22 °F).

Hypertufa was invented for use in alpine gardens. Alpine gardeners formerly used antique animal watering troughs, which became rare and expensive. (Source: Wikipedia - http://en.wikipedia.org/wiki/Hypertufa)
