Black Basalt Gravel 20mm 

Add bold definition and modern elegance to your outdoor space with our 20mm Black Basalt Gravel. This striking decorative aggregate features a deep charcoal-black hue that darkens to a rich jet black when wet, making it a standout choice for contemporary garden designs, driveways, and landscaping projects.

Product Features/Specifications:

Whether you're laying a sleek garden path or designing a bold border, Black Basalt Gravel 20mm offers both durability and visual appeal:

• Driveways & Pathways: The angular nature of basalt ensures excellent interlock, reducing stone movement under foot and vehicle traffic.
• Borders & Rockeries: Its dramatic dark tone contrasts beautifully with foliage, flowers, and other natural features.
• Water Features: Use around ponds or fountains for a stunning visual effect, while also aiding in drainage.
• General Ground Cover: Helps suppress weed growth and delivers a neat, high-end finish to any outdoor space.

Product Benefits:

Black Basalt Gravel is not only visually impactful but also extremely hard-wearing, making it ideal for high-traffic areas.
