20mm Aggregate (Screenings)

Strong & versatile | Excellent drainage | Ideal base material

Our 20mm Aggregate is a coarse, clean stone blend suitable for a range of construction and landscaping applications. Its larger particle size makes it ideal as a sub-base material for concrete slabs, driveways, paths, and drainage systems, where strength and flow-through capacity are essential.

Because the stones are relatively large, this aggregate permits water to pass through, reducing pooling and helping maintain stability under structural loads. It’s commonly used around pipe bedding, retaining wall backfill, and civil works projects.

Ideal for:

• Drainage and pipe bedding
• Backfill for retaining walls
• Structural and landscaping foundations
• Aggregate for concrete mix

Key Features:
✅ Coarse 20mm stone size for strength and stability
✅ Excellent drainage capacity — reduces waterlogging
✅ Suitable for load-bearing and civil applications
✅ Clean, screened material ready for use

Available in bulk or by the cubic metre for pickup or local delivery across Eltham, Research, Diamond Creek, and surrounding suburbs.
