Graded Aggregates

Overview

At Groundworx Grabhire Ltd., we supply graded aggregates, a crucial material for construction and landscaping projects. Graded aggregates are sorted by particle size, ensuring consistency and suitability for specific applications. These materials offer excellent strength, durability, and versatility, making them a reliable choice for a wide range of applications.

Whether you’re working on sub-bases, drainage, or decorative projects, our graded aggregates provide the perfect foundation. Their uniform particle size enhances compaction, stability, and drainage, making them indispensable for both commercial and residential developments.

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.

Common Sizes of Graded Aggregates

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.
