Primary 6F5 Fill

Our Primary 6F5 Fill is a coarse graded primary aggregate produced for heavy-duty groundwork and bulk fill applications where high load-bearing performance and structural stability are required. The material typically contains a blended crushed aggregate grading up to 125mm with reduced fines compared with MOT Type 1, which allows stronger drainage performance and makes it suitable for deep fill, piling mats, haul roads, site formation, and large-scale sub-base construction. Groundworkers and civil contractors regularly choose primary 6F5 where recycled fill may not meet specification requirements or where cleaner virgin aggregate consistency is preferred across commercial groundwork projects.

We supply this primary 6F5 fill across Manchester and surrounding North West areas for bulk delivery to construction sites, infrastructure works, access routes, and heavy plant operating areas. The larger aggregate grading helps the material compact into stable load-bearing layers while still maintaining better water movement than tightly bound sub-base materials. Contractors commonly use 6F5 beneath crane pads, temporary roads, deep hardstanding areas, and large commercial foundations where robust support and reliable installation performance are important. Loose load supply makes the material practical for machine-spread groundwork and high-volume site preparation works.
