Product Details

10/20 mm Black Basalt is an angular, hard‑wearing aggregate selected for projects requiring strength and a bold visual finish. Its deep charcoal to near‑black tones create a striking contrast in both contemporary and traditional landscapes. The fractured stone edges allow the material to interlock effectively, making it suitable for edged paths and driveways where surface stability is essential. This product is also known as Moorland Black.

The angular structure of Black Basalt helps minimise movement over time, ensuring a compact and dependable surface. Its dense, resilient composition allows it to withstand heavy footfall and vehicle traffic, maintaining its colour and form for years. This makes it a reliable choice for high‑impact decorative and functional landscaping applications.
