Choosing the right aggregate for your construction project is essential for both performance and cost-efficiency. Aggregates form the foundation of any build — whether you’re laying sub-base for a road, preparing drainage systems, or adding decorative finishes. 

Start with the Application 

Different types of construction projects require different materials. Here’s a breakdown to help you choose: 
 
Sub-base/Foundation Works: 
Use MOT Type 1, crushed concrete, or 6F5 for creating solid, load-bearing layers beneath roads, car parks, and building pads. 
 
Drainage and Pipe Bedding: 
Choose 20mm or 10mm gravel, washed pea shingle, or crushed stone. These aggregates allow water to flow and prevent pooling. 
 
Concrete Production: 
For mixing concrete on-site, sharp sand, ballast, and 10mm or 20mm gravel are standard. The right mix depends on the intended strength of the concrete. 
 
Decorative Areas: 
Use decorative gravels, limestone chippings, or granite for paths, driveways, and landscaping. These come in a range of colours and sizes to suit any visual style. 

Natural vs. Recycled Aggregates 

Recycled aggregates are increasingly used in place of virgin materials, especially for sub-bases. They're cost-effective and environmentally friendly — great for general fill and backfilling. 
 
However, some applications (like concrete production or structural layers) may still require certified virgin materials depending on regulations or project requirements.
