Graphite Slate Chippings

Graphite Slate Chippings are a versatile and attractive landscaping aggregate, ideal for driveways, pathways, borders, rockeries and general decorative garden projects.

The flat angular slate pieces settle neatly together to create a clean and textured finish that works beautifully in both contemporary and traditional outdoor spaces. Their natural appearance helps add contrast, definition and character throughout landscaped areas.

Slate chippings naturally deepen in colour when wet, enhancing their appearance and creating a more striking finish all year round.

Why Choose Graphite Slate Chippings?

The flat profile of slate chippings makes them comfortable to walk on while also providing excellent coverage for larger landscaping areas. Their durable and low-maintenance nature makes them a popular choice for both residential and commercial projects.

Decorative slate is suitable for use on driveways, garden paths, borders and rockeries, helping create texture and visual interest while complementing paving, planting schemes and outdoor features.

Unlike some decorative aggregates, slate does not significantly alter the pH level of the soil beneath it and can help support moisture retention within planting areas and borders.
