Tefrablack is a natural product deriving from the crushing and screening of black-grey volcanic lava, which is characterized by high porosity and structural endurance. Tefrablack has between 40% and 60% of void space for each granule; it is frost-resistant, chemically inert, insoluble, odourless, nontoxic and free of reactive silica, organic contaminants and minerals inflating when in contact with water. Due to its characteristics, Tefrablack can be used as mulch or as a decorative element for gardens, creating a wonderful visual effect.
