Endless Possibilities at Corker

Add interest and intrigue to your garden with Corker’s range of decorative aggregates. We stock an impressive choice of types, sizes and colours, so you’re sure to find the perfect products to turn your landscaping aspirations into reality.

Use one type to create a uniform theme, use two or three in different areas to create contrast, or think totally outside the box and mix products together!

All of our gravel, pebbles, shingle and chippings have a long lasting mulching effect. A layer of stones will insulate soil and improve drainage in cold, wet weather, and provide root shade and aid water retention in hot weather. Hard mulches are also brilliant at stopping weeds in their tracks, meaning you have more time to spend on the gardening jobs you enjoy.

Our decorative aggregates are suitable for driveways, paths, borders, rockeries, water features and much more.

Frequently Asked Questions

1. What are Black Chippings?
Black chippings are angular decorative stones with a deep charcoal to jet-black tone. They’re used to create striking, modern surfaces in gardens, driveways, borders, and paths.

2. What size are the chippings?
These chippings are graded to approximately 20mm, offering a bold, textured finish ideal for larger outdoor areas and high-contrast landscaping.

3. What are they made from?
Typically composed of crushed basalt or granite, black chippings are naturally hardwearing, UV-resistant, and frost-proof, making them ideal for year-round outdoor use.

4. Where can they be used?
Black chippings are versatile and well-suited for:

  • Driveways and parking areas
  • Garden paths and walkways
  • Borders and flower beds
  • Around water features or rockeries
  • Contemporary or minimalist designs

5. Do they hold their colour?
Yes. Their natural dark pigmentation is highly resistant to fading. When wet, they take on a deeper, glossier appearance, enhancing their visual impact.

6. Are they suitable for driveways?
Yes. Their angular shape helps them lock together when compacted, making them ideal for driveways. A proper sub-base and edge restraint are recommended for best performance.

7. Do they help suppress weeds?
Yes. When laid over a weed control membrane, black chippings help block light and reduce weed growth while allowing water to pass through freely.

8. Are they pet- and child-friendly?
Yes. They are safe to use in areas accessed by pets or children. However, due to their angular shape, they may be less comfortable under bare feet compared to rounded gravel.

9. Can they be used with other aggregates for contrast?
Absolutely. Black chippings work beautifully alongside lighter stones (e.g. buff or silver) to create striking contrast, defined pathways, or patterned gravel gardens.

10. How much will I need?
For decorative coverage at a 40mm depth, 1 bulk bag (approx. 850kg) typically covers 8–10m². For driveways, a deeper layer may be required for durability.
