Great question!

The availability of hardscape materials is usually determined by the consistent supply from the "OEM" e.g. harvesters, miners, etc. And usually when a hardscape material is discontinued, it is because either the price becomes unreasonable or because the supply can no longer meet a certain degree of consistency.
