6F2 / 6F5

Recycled Aggregates for Sub-Base Construction

6F2 and 6F5 are types of coarse, recycled aggregates derived from crushed demolition materials such as concrete, brick, and stone. The process involves crushing and screening these materials to produce a mix of angular stone that ranges from 75mm down to dust, with particles as fine as 0mm. While both 6F2 and 6F5 serve similar purposes, 6F2 is generally processed to a higher standard with fewer impurities compared to 6F5. Despite this distinction, both types are suitable for bulk fill and engineering applications.

6F2 / 6F5 Aggregates: Key Benefits

Load-Bearing Strength

These recycled aggregates offer excellent load-bearing capabilities, making them ideal for use as a capping layer beneath roads, tracks, or large hardstanding areas. The angular nature of the crushed stone, brick, and concrete ensures that the pieces lock together effectively, providing good compaction and creating a stable base.

Economical Choice

6F2 and 6F5 aggregates are more cost-effective compared to primary aggregates because they are made from recycled materials. This approach not only reduces purchase costs but also lowers disposal expenses by reusing demolition waste rather than sending it to landfill.

Common Applications for 6F2 and 6F5

• Road and track construction
• Car parks and hardstanding areas
• Sub-base for buildings and yards
• Temporary haul roads
• General bulk fill

6F2 and 6F5 Aggregates: Practical Tips

When selecting 6F2 or 6F5 aggregates from Gravel Base, consider the specific requirements of your project to ensure optimal performance. Proper site preparation and compaction are essential to achieve the desired stability and durability. These recycled aggregates provide a practical, economical solution for a variety of construction needs, whether you are building a new road or laying a sub-base for a yard.
