Professional Application Tips
To get the most out of your 40mm Rio Grey Riverstone, follow these expert landscaping guidelines:
- Base Layer: To prevent the larger stones from migrating into the soil, always install a Commercial Grade Weedmat before spreading. This keeps the stones clean and ensures high-contrast visual appeal.
- Depth Calculation: For a solid “stone carpet” effect that hides the sub-grade completely, we recommend a minimum depth of 50-60mm.
- Erosion Control: These stones are excellent for lining dry creek beds or areas where heavy roof run-off occurs, as their weight prevents them from washing away easily.
- Finishing: As a natural product, these may arrive with a light layer of quarry dust. A quick hosing after installation will bring out the deep, natural grey tones of the stone.
