Black Basalt 20mm Standard Bag

20mm black basalt is a dramatic gravel that looks black when wet and dark charcoal grey when dry. It can be used to create contrast and showcase bright coloured plants and garden features. Bulk bags are perfect for large garden projects, driveways, pathways and borders. Basalt is a dark volcanic rock. Available in standard and bulk size bags. The volcanic rock is extremely hard-wearing and durable, shiny when wet, making it the ideal addition to any landscape. The bulk bag is approximately 800kg and a regular pack weighs about 25 kg. Please note: Timber and stone are natural materials, and as such, variation in colour, texture, and natural markings is to be expected. We strive to represent our products as accurately as possible through imagery; however, colours and shades may appear differently depending on individual monitor settings such as brightness, temperature, and contrast. These variations are not considered defects.
