Pumice hero element

A Natural Innovation

LAVA pumice stone is a unique natural resource that drives innovation in the construction and landscape architecture sectors. It is a chemically inert porous volcanic mineral that occured from successive eruptions of the Nisyros volcano. These eruptions took place approx. 50,000 years ago and resulted in the formation of the Yali island.

The porous structure of LAVA pumice stone is due to the cavities created by escaping steam as lava cools down. This unique quality, makes it a totally natural resource that is turned into efficient, added-value industrial solutions across the world. LAVA pumice stone has a wide variety of applications in many areas. From roofing and transport to nutrition and clothing, offering astonishing solutions. It is a natural resource combining environmental friendliness with the absence of chemical processing.
