BASALT
Basalt is a magnesium-rich primitive rock containing also Silicon, Iron & Calcium & Trace minerals. It is a natural product, environmentally friendly with no elutriation/leaching into ground water. It is also non-toxic & safe to aquatic animals and plant-life.
We are fortunate to have an excellent supply of raw basalt rock which we dry, crush and screen into various grades for a number of different industries at our factory in Auckland.
