At Composting New Zealand, we stock a range of drainage metal to meet your needs.
Pea metal (crushed greywacke rock)
Commonly used as a drainage and filtration fill, our 20mm pea metal is also a popular alternative covering for driveways, or as a decorative surface in gardens and borders.
Priced competitively, pea metal is a product that only requires a shallow application (2cm) when implemented as a protective driveway cover, resulting in even more cost saving.
Please note that our Drainage Metal (Pea Metal) product is sourced from various different distributors and quarries. We cannot guarantee that any new purchase will necessarily match previously stocked or procured Pea Metal.
