Application

To ensure your Rio Grey Riverstone 60–80mm installation looks professional and lasts a lifetime, follow these tips:

Underlayment: Due to the weight of the 80mm stones, we highly recommend a Non-Woven Weedmat. This prevents the stones from migrating into the soil and keeps your grey palette crisp and mud-free.
Natural Sculpting: When creating a dry creek bed, mix this large 60-80mm grade with our 40mm Rio Grey and Feature Boulders to replicate a natural river-worn look.
Edge Retention: Use these larger stones as a natural retaining edge for smaller pebbles or mulch on sloped areas to prevent material washaway during heavy rain.
Coverage: Aim for a depth of roughly 100mm. This ensures that the stones interlock tightly enough so that no weedmat is visible from above.
