Maintenance
Green granite chippings are generally low maintenance, especially when a heavy duty membrane is installed underneath to suppress weeds, with most work limited to the occasional removal of debris. Occasional power washing is advisable to maintain the original colour and prevent algae or moss buildup. Natural quarry materials also may have dust, which should be hosed off with water at the time of installation.
For areas with heavy footfall, such as paths or footpaths, replenishment of chippings may be required over time to maintain depth and coverage. When used with weed control fabrics, Welsh green granite chippings can significantly reduce the time spent on garden upkeep.

Purchasing Tips
When purchasing green granite, consider the size and quantity necessary for your project. Where available, it is cost-effective to request a sample to assess the stone’s colour and quality against your design requirements. Also, consider the size you’ll need; for instance, green granite chippings 20mm are typically used for driveways, while smaller green granite 10mm are better suited to footpaths.
Using our gravel calculator to get an unbiased estimate for your project needs is one of the best and easiest ways to get the right amount without the risk of shortfalls or over-spending – all you need is a few measurements of the space. Ordering in bulk bags is often more cost-effective than smaller quantities. Also, always ensure you consider the delivery aspects, especially vehicle access to the site.
