Volcanic Lava Rock is mainly extracted and crushed in Germany. Volcanic rock chippings are porous and brown. Due to its low Specific gravity and permeability, it is a good option for an alternative foundation where low Specific gravity is important. Lava rock is generally used for the construction of natural filters. Lava rock is not washed during extraction, the dust is washed away naturally by rain.
