River Rock 20MM Decorative Gravel: Smooth, Natural, and Timeless
What It Is
River Rock 20MM Decorative Gravel is a smooth, rounded stone known for its natural tones and soft appearance. Its organic shape creates a relaxed, coastal feel that works beautifully in both modern and traditional landscapes.
What It’s Made Of
Formed naturally over time by water movement, these stones are smooth and rounded with minimal sharp edges. The 20mm sizing provides consistent coverage while maintaining a natural river washed look.
What It’s For
River Rock 20MM Decorative Gravel is ideal for landscaping projects where a softer finish is preferred:
Garden Beds: Adds a natural, relaxed texture around plants and shrubs.
Drainage Areas: Suitable for areas requiring water flow and movement.
Pathways: Creates decorative walkways with a smooth underfoot feel.
Water Features: Complements ponds and fountains with an authentic river look.
Coastal and Natural Designs: Perfect for organic, earthy landscaping styles.
How to Use It
Spread evenly over a prepared base to a recommended depth of 50 to 75mm depending on application. Because of its rounded shape, edging is strongly recommended to help contain movement. For improved weed control, consider installing geotextile fabric underneath.
Features and Benefits
Smooth Rounded Finish: Soft natural appearance with no sharp edges.
Natural Earth Tones: Blends easily with plants, timber, and stone.
Improved Drainage: Allows water to move freely between stones.
Durable and Long Lasting: Performs well in Australian conditions.
Low Maintenance: Does not break down over time.
Bulk Supply Available: Sold by the cubic metre for projects of any size.
Coverage Example
At a depth of approximately 50mm, 1 cubic metre will cover around 12 to 15 square metres depending on ground preparation and placement.
Practical Notes
Natural Variation: Colour, size, and tone may vary as this is a natural product.
Stone Movement: Rounded stones may shift more than crushed gravel, so edging is recommended.
Site Preparation: Proper levelling and base preparation will improve stability and finish.

Frequently Asked Questions
What can decorative stone be used for?
Decorative stone is ideal for garden beds, pathways, feature areas, borders, drainage zones, and modern landscaping designs. It adds texture, contrast, and long lasting visual impact to both residential and commercial projects.
How much decorative stone do I need?
The amount required depends on the length, width, and depth of the area you are covering. A common depth for decorative stone is around 75–100mm, depending on the look and application. If you are unsure, our team can help you calculate the correct cubic metre volume before ordering.
Is decorative stone low maintenance?
Yes. Decorative stone is a low maintenance landscaping solution. Once installed properly with suitable edging and weed matting if required, it provides long term coverage without needing frequent topping up like organic mulches.
Will the colour fade over time?
Natural stone retains its colour well in Australian conditions. Some surface dust may wash off after installation, but the core stone colour remains consistent over time.
Do I need to prepare the area before installing stone?
Proper preparation is important. We recommend clearing the area of weeds, levelling the ground, and compacting the base where required. Installing edging helps keep the stone contained and maintain a clean finish.
Do you supply decorative stone in bulk?
Yes. Our decorative stone is sold by the cubic metre and supplied in bulk. This makes it suitable for both small garden upgrades and large scale landscaping projects.
What access is required for delivery?
Delivery requires clear and safe access for our trucks to tip the material on site. Please ensure there is adequate space and no overhead obstructions. If access is restricted, contact us before ordering to discuss options.
