Black Grey Chippings 20 mm is a premium decorative aggregate, perfect for driveways, pathways, borders, rockeries, and water features. Naturally quarried, this hard-wearing stone appears dark grey when dry and transforms into a striking, glossy black when wet, adding a sleek and modern finish to any outdoor space. Its angular shape creates a stable surface ideal for high-traffic areas, while excellent drainage reduces puddling and weed growth. Eco-friendly and sustainable, black basalt—also known as black granite gravel—is plant-safe and fish-friendly once cleaned, making it suitable for ponds, flowerbeds, and garden features. A stylish, durable choice for landscaping projects.
