Pumice
We are transforming the world with the power of nature
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.

specifications
The consistent quality of LAVA pumice stone stems from the continuous homogeneity of the deposit and rigorous controls integrated into every production process stage. This monitoring and quality control process ensures the high quality standards required in a wide range of applications.
At LAVA we are committed to producing high quality products that meet the strict requirements of European Standards. Our product quality is confirmed with the CE marking, which guarantees compliance with safety standards. In addition, they are subjected to strict ASTM compliance testing to ensure their quality and durability.
LAVA pumice stone has an Environmental Product Declaration since 2021. More specifically, the EPD is compliant with ISO 14025 and EN 15804 and is verified by an independent accredited authority, while it is published via the International EPD System, the most popular EPD Program, proving that LAVA pumice is the optimal solution for sustainable construction with improved environmental footprint, especially bioclimatic projects that aim at certifications from the most important international building eco-labels (e.g. LEED, BREEAM).
