What are Graded Aggregates?

Graded aggregates are aggregates that have been sieved or screened to ensure a specific size range. These materials are produced by crushing and screening quarried stone. The result is a high-quality material with consistent particle distribution, ideal for various construction purposes.

Groundworx Grabhire Ltd. supplies a range of graded aggregates to suit diverse applications:

  • 4-20mm: Ideal for ready mix concrete applications and pipe bedding applications.
  • 20-40mm: Commonly used for drainage applications in soakaways or trenches, also commonly used for decorative landscaping for gardens and pathways.
  • 10-63mm: A broad grading of aggregates used in specialist applications such as drainage layers for large infrastructure projects.
  • 40-75mm: Used as a heavy duty, free draining base layer in road construction or pathways.
  • 150-50mm: Large course aggregate that can be used as fill for gabion baskets, or provide stability in embankments and flood defences.
