Natural drainage gravel is an essential material for managing water flow and preventing water build-up around your property. At Rock ‘N’ Soil, we supply crushed blue metal drainage gravel in a range of sizes to suit different drainage, landscaping and construction applications. Whether you're installing a French drain, backfilling a retaining wall or preparing a drainage trench, we have aggregate options to suit your project.
Our range includes 20mm drainage gravel, 10mm blue metal and smaller 5–7mm aggregate, as well as a larger 40mm option. The angular, crushed stone allows water to move freely while providing a durable and stable material for drainage systems. The right size will depend on your application, water flow requirements and the drainage infrastructure being installed.
If you're looking for 20mm drainage gravel or quality blue metal in Brisbane, explore our natural drainage range at Rock ‘N’ Soil. Available in bulk quantities, with delivery and click and collect options for residential, commercial and trade projects.
