Create clean lines and contemporary visual impact with Mosaic Flat Grey Pebbles. These decorative stones feature a deep gunmetal grey tone and naturally tumbled, flattened profiles that sit closely together for a sleek, mosaic-inspired finish.
Their understated colour works beautifully with concrete, timber, natural stone and architectural planting, making them an excellent choice for modern courtyards and carefully designed outdoor spaces.

Installation & Care
Follow these general guidelines to achieve a neat finish and maintain the appearance of your Mosaic Flat Grey Pebbles.
- Prepare the area: Remove weeds, loose soil and debris before installation.
- Use a suitable membrane: Lay geotextile or weed mat beneath decorative areas where appropriate to help reduce weeds and minimise mixing with soil.
- Spread evenly: A decorative depth of approximately 30–50mm is a general guide. Adjust to suit the application and the desired coverage.
- Install edging: Use suitable edging to keep the flatter pebbles neatly contained, especially beside lawns and pathways.
- Clean periodically: Rinse when needed to remove dust and surface debris. Use a blower on a low setting to clear leaves.
- Maintain water features: Periodically flush the stones to remove fine sediment and refresh their appearance.
Installation depth and preparation may vary depending on drainage, site conditions and the intended application.
