Aggregates & Decorative Stones — Gravel, Pebbles & Blue Metal

Quality Aggregates for Every Job

Whether you're laying a driveway, building a concrete slab, improving garden drainage or adding character to a landscape, the right aggregate makes all the difference. Martins Building & Landscape Supplies stocks a full range of structural and decorative aggregates for residential, commercial and trade projects across Sydney. From workhorse materials like blue metal and roadbase to premium decorative pebbles, you'll find it here — available in 20kg bags or bulk for larger jobs.

Bags or Bulk — Which Is Right for You?

Most aggregates at Martins are available in both 20kg bags and bulk quantities. Bags suit smaller residential jobs, top-ups and DIY projects where precision matters. Bulk orders (loose tipped or in bulk bags) are the better value option for landscapers, builders and larger home projects. If you're not sure how much you need, our team can help you work out quantities before you order.
