Blue Slate 40mm Granite chips bring a rich, cool-toned finish to any outdoor space. Priced at £225, this 750kg bulk bag covers approximately 14m2 at 40mm depth.

These 20-40mm natural slate granite chips work well on pathways, driveways, and garden borders. The larger chip size provides excellent drainage while creating a striking decorative surface.

Blue slate darkens when wet, giving your garden a deeper, more dramatic look after rainfall. The natural colour variation means no two areas look identical.

Spread directly onto a weed membrane for best results. The 40mm chip size stays in place better than smaller grades, making it a practical choice for sloped areas and high-traffic paths.

Each chip is made from natural British slate, so the colour will not fade over time. Safe around fish ponds and water features once rinsed thoroughly before use.
