About Our Black River Rocks
Black River Rock is a smooth, naturally rounded river stone with rich black tones and subtle earthy undertones. The 40mm grading gives each stone a substantial size that stands out in modern, minimalist and architectural landscapes.
These stones are especially popular for:
-
Decorative garden beds
-
Pathways and borders
-
Highlighting feature plants, root balls or architectural elements
-
Water features, ponds and dry creek beds
-
Creating contrast against white render, bright foliage or timber features
-
Fire pit surrounds
Black River Rock also enhances drainage and provides long-lasting ground cover that stays visually consistent over time.
Why Choose Hampton Black River Rocks?
- Bold, Striking Appearance – The deep charcoal and black tones create a dramatic, high-contrast look that instantly elevates modern landscaping.
- Perfect for Water Features – Their naturally smooth, rounded finish makes Black River Rock ideal around ponds, streams, fountains and decorative water elements.
- Durable & Long-Lasting – These dense river stones resist fading, weathering and breakdown, making them suitable for long-term use in any climate.
- Low Maintenance – Once installed, they require very little upkeep, don’t decompose, and help keep garden areas neat and tidy.
- Improves Drainage – Their rounded shape allows for excellent water flow, preventing waterlogging in garden beds and around structures.
- Great for Highlighting Features – The dark colour contrasts beautifully against plants, white render, timber, concrete and stepping stones.
- Weed Suppression – When used with a weed mat, Black River Rock forms an effective barrier that blocks sunlight and significantly reduces weed growth.
What You Need to Know About Black River Rocks
While Black River Rock delivers a premium look, there are a few considerations:
- As a decorative river stone, it may be more expensive upfront than standard gravels.
- Because it’s a natural product, colour and shape may vary slightly from batch to batch. For large areas, ordering all required quantities at once ensures a consistent finish.
- A small amount of dust is normal from transport. A quick rinse after installation brings out the deep black tones.
- Stones are heavy. Large projects should be planned with delivery and installation in mind.
Once installed, it provides a long-lasting, low-maintenance surface that doesn’t break down over time.
How to Use Black River Rock 40mm
To achieve the best results with Black River Rocks, follow these steps:
1. Preparation
Start by clearing the area of weeds, debris and existing mulch.
Install a weed mat or landscape fabric to improve long-term weed control and keep the stones clean.
If creating a pathway, ensure the base is level and compacted.
2. Application
Garden beds & decorative areas: 50–75mm depth
Light-use pathways: 75–100mm depth
Drainage zones: Apply deeper as needed for effective water flow
Spread the stones evenly for a consistent, dense finish.
3. Maintenance
Occasionally rake the stones to maintain even coverage.
Hose down the surface from time to time to remove dust and refresh the colour.
Top up areas only if they shift due to foot traffic or weather.
Pro Tip
Use Black River Rock around white, cream or light-coloured features for maximum contrast.
These stones also perform exceptionally well in Japanese-style gardens, dry creek beds and modern coastal landscapes.
