Quick answer

40–80mm River Stone is a larger, smooth, naturally rounded stone ranging from golf ball to tennis ball size, in ivory and cream through to rich browns and greys. Its weight keeps it in place during storms, helps prevent soil erosion and assists drainage. It suits gabion walls, dry creek beds, ponds, garden mulching and fire pit surrounds. Lay it about 80–100mm deep; one cubic metre covers roughly 10–12.5 m².

Size benefits

These stones range from golf ball sized to tennis ball-sized and come in smooth, naturally rounded surfaces. They feature natural colouration ranging from soft ivory and cream through to rich browns and greys. Each stone has been naturally smoothed over time, creating a polished appearance suitable to many garden styles.

Weather resistant

Unlike organic mulches requiring regular replacement, these durable river pebbles withstand harsh Australian weather conditions including intense UV exposure, heavy rain, and temperature fluctuations. Their substantial size means they stay in place better than smaller gravel, resisting displacement during storms whilst providing long-lasting coverage.

Common questions about 40–80mm River Stone

What is 40–80mm river stone used for?

Gabion baskets and walls, dry creek beds, water features and ponds, decorative borders, fire pit surrounds and water-wise garden mulching.

How much 40–80mm river stone do I need?

One cubic metre covers about 10–12.5 m² at 80–100mm deep. Larger stones need more depth so the ground underneath is fully covered.

Can I use 40–80mm river stone in gabion baskets?

Yes. Choose a mesh with openings smaller than the smallest stones so they can’t fall through. Call the yard if you want help matching stone to your baskets.

Will larger river stone wash away in heavy rain?

Its size and weight mean it stays in place far better than smaller gravel, which is why it is used for dry creek beds and stormwater channels.
