My Take on Hypertufa
by Robert Charles Murray
A snippet from my white paper: “My Take On Hypertufa”
Hypertufa is a man-made, cement based, replacement for, yup here it comes, tufa. Kinda like saying mud is a replacement for dirty water – well maybe not exactly.
Anyway, it seems hypertufa has another systemic ingredient, otherwise it cannot be referred to as hypertufa; peat moss. A point of simplification here: to be an authentic imitation of authentic tufa, hypertufa must contain peat moss.
Let’s look at some of the qualities of the “real” tufa; it’s porous, it has embedded vegetation (in various stages of decomposition), it is light weight, and it can absorbs it’s own weight in water.
Hypertufa, the peat moss variety, is a cement-based creation resembling rock that gets all the attributes of “real” tufa from the peat moss not the cement. It is the peat moss in hypertufa that absorbs water, supplies nutrients (decaying vegetation), and reduces the overall weight. But the same attributes could be credited to almost any decaying organic compost or growing medium. So why is peat moss so vital to hypertufa?
The simple answer: it isn’t.
Research indicates that most “mud-slingers” use peat because “they” were told it MUST contain peat moss or it isn’t an authentic imitation of authentic tufa – I think I mentioned that before. The cement’s only value is to provide a shape to suspend the peat moss.
