50-150mm Graphite Slate Gabion Stone

Graphite Slate Gabion Stone is a high-quality natural slate graded 50–150mm, perfect for gabion baskets, planters and decorative walls. When dry, its pale blue-grey surface is subtle, while rain or washing deepens the colour to a striking charcoal black. The flat, angular shape ensures a compact and stable fill with a neat gabion face. Also known as Charcoal Slate Rockery, this name reflects its distinctive dark shades and suitability for decorative rockeries, borders, water features and aquatics. Its fish-friendly qualities make it versatile for both structural and decorative landscaping projects.
