Plum Slate 40mm Granite arrives in a 750kg bulk bag, ideal for pathways, driveways, and borders. The larger 20-40mm chips provide bold colour and excellent ground coverage. Order today for just £229 with free UK delivery.

Made from 20-40mm natural slate granite chips, this larger-grade aggregate creates a bolder surface than the 20mm variant. The angular chips lock together to form a stable, low-maintenance surface underfoot. Spread at 40mm depth, one bag covers around 14m² — enough for a generous garden path or driveway border.

The rich plum and purple tones deepen when wet, creating a striking finish after rainfall. These stones are fish-friendly once washed, making them suitable for pond surrounds and water features. The warm colour palette pairs well with soft grasses, lavender, and Mediterranean planting schemes. Use alongside lighter aggregates for a layered, natural effect.
