Benefits:

• Natural water repellent. It helps to regulate the flow of water through pot plants and planter boxes, ensuring efficient drainage.
• Formed across centuries by rapid cooling of lava, it is a natural product and thus promotes heavy and rapid drainage.
• Although light, it is immensely robust and therefore can support a solid amount of weight when placed in or behind retaining walls or raised planters.

Although not as heavy as other gravel products, it is still solid and robust and appropriate footwear is recommended as the product can be quite sharp from the natural formation and mining processes.
