7mm Scoria
Lightweight volcanic drainage, 7mm scoria for ag-drains, planter drainage and anywhere weight matters.
About this product
Scoria is vesicular volcanic rock, full of air pockets, roughly half the weight of basalt, and naturally free-draining. The 7mm grading suits fine drainage applications: agricultural drains, planter boxes, green roofs and drainage cells where every kilogram counts.
Sourced from Victorian scoria cones, it’s also a distinctive decorative ground cover. We supply 7mm alongside 14mm and 20mm gradings, by the tonne or truckload.

How much do you need?

100 m² at 100 mm deep = 10 m³ × ~0.9 t/m³
