Primary 6F5

Primary 6F5, also known as capping aggregate, is a coarse quarried material produced from limestone, granite, ragstone, or gritstone. With particles ranging from fines up to 125mm, it provides excellent compaction and load-bearing strength. Commonly used as a capping layer before Type 1 or Type 2, it is also suitable for piling mats, haul roads, car parks, and general fill where recycled alternatives are not available. Hardwearing and weather-resistant, 6F5 forms a strong, stable base for demanding construction projects.
