Bulk Bag Black Basalt 20mm

Black basalt is a circa 20mm volcanic rock chipping. It is highly durable and resistant to moss growth. When wet, the stone offers a very dark pitch black shading, when dry the stone offers a more varied black and charcoal hue. Basalt chippings are well suited to tonal grey garden designs, commonly used in borders, pathways, planters and edgings.

We approximate 1 bulk bag to cover 10m2 at a depth thickness of 50mm.
