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 with the aggregate.

Spread the 20mm Golden Flint chippings evenly over the prepared sub-base to the recommended depth, typically around 40mm to 50mm for borders and footpaths, or 50mm to 75mm for driveways. Rake the chippings to ensure an even distribution across the entire area.

Check the finished surface level and slope to ensure proper drainage away from surrounding structures. Ensure the aggregate 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 is 20mm golden flint?

20mm golden flint, often called golden gravel, is a popular decorative aggregate made from crushed natural flint. It features a warm mixture of golden-yellow, buff, chestnut, and cream tones, with an angular shape that gives it a textured appearance.

What is 20mm golden flint used for?

Golden flint is widely used for garden borders, footpaths, rockeries, plant toppers, and driveways. Its bright, warm colors make it ideal for contrasting against greenery and updating tired garden beds.

Is 20mm golden flint suitable for driveways?

Yes. Golden flint is one of the most durable materials available for driveways. At 20mm, the angular stones interlock under weight to form a firm surface that resists shifting and won't get stuck in car tire treads.

How does the appearance of golden flint change when wet?

When dry, golden flint displays soft, natural pastel shades of cream, yellow, and tan. When wet, the colors intensify into rich, vibrant golds, ambers, and deep warm browns.

Are golden flint chippings fish-friendly?

Yes. Flint is an inert natural stone that will not alter the water chemistry, pH balance, or mineral levels. It is safe to use around ponds, streams, and decorative water features (washing the stone first to remove dust is recommended).

Will 20mm golden flint wear down or crush over time?

No. Flint is an extremely hard, resilient rock type. It is resistant to weathering, frost damage, and heavy traffic, ensuring it retains its structural integrity and sharp definition over many years.
