Pumice Stone

What is pumice stone?

The pumice stone (in Greek is called "Ελαφρόπετρα" the combination of the words ελαφρύς + πέτρα, meaning light + stone) is a porous volcanic mineral, chemically inert. It is created by the volcanic action and the porous of the material due to the voids created by the steam escape during cooling of the lava.

Typesof Pumice Stone

Because of its low weight and low density, its acoustic and other heat-insulating and sound absorbing properties it is an ideal aggregate for the creation of construction products, for soil mixture, for substrate, green gardens and many other uses. The granulometries we offer are different depending on the use.

Pumice Stone 0-4 mm

Pumice Stone 0-8 mm

Pumice Stone 2-4 mm

Pumice Stone 2-10 mm

Pumice Stone 8-16 mm


Its inorganic character, its appropriate size grading, its durability, its chemical and mechanical characteristics and its low cost are significant advantages for its use in a variety of applications such as agriculture (hydroponic and non-crop farming), crafting applications, geotechnical construction, pharmaceutical and cosmetic uses. Pumice grains are very hard, because they are made of silicate material. This is why it is used as an excellent and unique material in the fabrication process of jeans. Pumice stone is proving to be a highly competitive material as it offers solutions even in difficult application problems.
