20mm Plum Slate Chippings Bulk Bag (800kg)

20mm plum slate chippings produced from natural slate deposits in Wales. Crushed and carefully screened to a nominal 20mm size, these chippings have a flat, angular profile that allows each piece to interlock when laid. This natural “locking" action creates a firm, stable surface that resists shifting underfoot, unlike rounded aggregates which tend to move or roll.Their structure also maintains excellent drainage, preventing surface water from pooling. This makes them highly practical for garden paths, driveways, beds, and borders, as well as for decorative ground cover where both function and appearance matter. Their natural colour range is dominated by rich plum and purple tones, complemented by occasional grey, blue, or green veins. When wet, the colours intensify, creating a deeper, more dramatic appearance that changes with the weather. Beyond appearance, the slate is permeable, helping water drain through easily; durable, resisting frost and heavy rain; and low maintenance, needing only occasional raking or top-ups. Unlike organic mulches, it does not rot or decompose, ensuring a long-lasting surface.
