6F2 and down subbase is type of crushed, recycled aggregate widely used in construction and civil engineering projects up and down the country. It’s made from demolition waste such as crushed concrete, brick, tarmac and sometimes stone, which are screened and processed to form a coarse, granular material. The term “60mm and down” means that the largest pieces in the mix are 60mm in size, but it also includes smaller particles and fine materials. This varied particle size helps it compact well, creating a solid and stable base.
One of the standout features of 6F2 is its versatility. It’s ideal as a bulk fill material during site preparation and is frequently used to create a firm subbase layer beneath roads, driveways, patios, and building foundations. By compacting well and distributing loads evenly, it provides excellent structural support for surfaces that will eventually bear heavy traffic or loads. It also improves drainage and helps prevent future issues such as settling, sinking, or surface cracking making it a reliable choice for long-term performance.
Who Uses 6F2 Subbase?
The construction industry is the primary user of 6F2 60mm and down. Builders and groundworkers use it in residential, commercial, and industrial projects for everything from house footings in Halifax and garden landscaping to major roads in Leeds or car parks in Wakefield. Civil engineering firms also rely on 6F2 for large infrastructure works such as railway embankments, motorway upgrades, and airport runways.
The landscaping sector makes use of it as well, especially for levelling out ground before turfing or installing patios and driveways. In these cases, its ability to provide a flat, compact base ensures that decorative surfaces remain even and long-lasting.
Utilities and infrastructure providers also use 6F2 during trench backfilling and pipe laying, especially when access to virgin aggregates is limited or when cost savings are a priority.
