Alpine White Gravel (20mm)

Alpine White Gravel (20mm) is a premium decorative stone used to create a bright, clean finish in landscaped areas. Its smaller 20mm size makes it particularly versatile for:

• Garden beds
• Decorative ground cover
• Rockeries
• Around feature trees and shrubs
• Water features
• Pathways and stepping stones
• Contemporary and coastal landscape designs

To calculate how much Alpine White Gravel (20mm) you need for your project, measure the length and width of the area where the stones will be placed.

Next, determine the desired depth of the stones. The required depth will vary depending on your project and the area you need to cover.

Once you have your length, width, and depth measurements, you can use our cubic metre calculator above or calculate the volume manually using the following formula:

Volume = Length × Width × Depth

Recommended Depth: As a general guide, we recommend laying Alpine White Gravel (20mm) at a depth of 40–50mm. However, the ideal depth will depend on your project and the area you need to cover. As a smaller decorative stone, 20mm gravel can generally be spread more evenly than larger stone at the same depth.

Yes. Alpine White Gravel (20mm) has the same bright white appearance as our larger 20–50mm Alpine White Gravel. It is one of the brightest white decorative stones in our range and is ideal for creating a clean, vibrant finish in contemporary, coastal and other landscape designs.

The 20mm size provides a smaller, more consistent stone profile, making it a versatile option for areas where you prefer a finer decorative gravel appearance.

Proper preparation helps minimise weed growth, improves drainage and creates a long-lasting decorative finish. To install your Alpine White Gravel (20mm), we recommend following these steps for a neat and professional finish:

1. Prepare and level the area.
2. Install weed mat to help prevent weed growth.
3. Install garden edging to keep the gravel neatly contained.
4. Spread the gravel evenly to the desired depth.
5. Rake the gravel to create an even, natural-looking finish.
