As an approximate guide, one bulk bag will cover:

• 10–12m² at a depth of 50mm

• 6.5–7.5m² at a depth of 75mm

• 5–6m² at a depth of 100mm

Garden borders, flower beds, and footpaths commonly require around 40mm to 50mm of decorative chippings, while domestic driveways typically require approximately 50mm to 75mm depending on the ground conditions and sub-base.

These figures are estimates only. Actual coverage will vary according to the bag weight, ground conditions, compaction and the accuracy of the excavation.

20mm Moonstone decorative chippings are intended as a decorative surface, border, or driveway topping. Colour, natural veining, and angular shape can vary according to the source of the stone.

Excavate the area to the required depth and prepare the ground appropriately. A suitable geotextile membrane may be required to prevent weed growth and stop the subgrade from mixing.

Spread evenly over the prepared sub-base to the recommended depth. Rake or lay by hand to ensure an even, flat distribution across the entire area.

Check the finished surface level and slope to ensure proper drainage away from surrounding structures. Ensure the depth is consistent to prevent exposed patches or uneven surface layers.

Requirements vary according to ground conditions, loading, and the intended use of the surface. Follow the project specification or seek professional advice where appropriate.

What colors are featured in Moonstone Chippings, and how do they look when wet?

Moonstone Chippings feature a striking blend of translucent quartz, light greys, soft creams, and dark slate-black flecks. When dry, they offer a subtle, shimmering pastel look that brightens shaded areas. When wet, the colors darken dramatically, highlighting the bold contrast between the light quartz and the dark charcoal tones.

What are the primary landscaping uses for 20mm Moonstone Chippings?

The 20mm size is exceptionally versatile and well-suited for garden pathways, flower bed borders, rockeries, patio edging, and plant pot top-dressing. The angular stones interlock underfoot, forming a flat, comfortable surface to walk on while keeping borders looking tidy.

Are 20mm Moonstone Chippings suitable for driveways?

Yes, 20mm Moonstone Chippings are suitable for driveways. Because the stone is angular and durable, it locks together effectively under vehicle tires, preventing excessive movement and rutting compared to rounded stones.

Are Moonstone Chippings fish-friendly?

Most Moonstone aggregates contain quartz and flint, which are naturally inert and fish-friendly. However, because some batches can contain small amounts of limestone, it is recommended to thoroughly wash the chippings and test a sample in water before introducing them to an active fish pond.

How do Moonstone Chippings assist with weed control and drainage?

Moonstone Chippings provide excellent natural drainage, allowing rainwater to soak freely into the ground to prevent pooling. When laid over a high-quality geotextile weed membrane, the heavy stone layer blocks sunlight to prevent weed seeds from taking root, while helping the underlying soil retain moisture during hot weather.
