Metal Supplies on the Central Coast

Blue metal is a type of crushed basalt rock, known for its strength and angular shape. It's often used in drainage systems, concrete mixes, and road construction. Gravel, by contrast, is generally more rounded and comes in various compositions, including river gravel or crushed stone. While both are used in landscaping and construction, blue metal is preferred for applications that require superior drainage, strength, and minimal movement. Gravel, especially rounded types, is more often used decoratively or in garden beds.

Yes, recycled concrete is a sustainable and cost-effective alternative to traditional aggregate. It’s made from crushed construction waste like old concrete slabs, footings, or pavement, and sorted into various sizes for reuse. Recycled concrete works well for backfilling, creating compacted sub-bases, and even under new concrete slabs. It offers decent compaction, drainage, and structural support, though it may not always be suitable for high-spec or heavily loaded applications. Always check particle size and compaction properties for your specific project.

For effective drainage, coarse materials like blue metal in sizes ranging from 10mm to 20mm are ideal. The angular shape of crushed stone allows for water flow while preventing soil movement. Drainage metal is commonly used behind retaining walls, around soak wells, in French drains, and beneath raised garden beds. It's important not to use fine materials like crusher dust in drainage applications, as these can compact too tightly and restrict water flow. Using a geo-fabric around the drainage zone also helps prevent clogging.
