Our high-quality 0/20mm Ballast is a premium primary sea-dredged aggregate. It is a carefully proportioned blend of 0/4mm Sharp Sand and sharp stones/gravel measuring up to 20mm, providing a heavy, durable mixture ideal for making concrete and providing coarse drainage fill.
This aggregate is naturally rugged, hard-wearing and coarse, ensuring that it provides excellent load-bearing capacity and stability when used in structural groundworks, sub-bases or heavy fill applications.
- It features a coarser, more gravelly texture than standard sharp sand, making it essential for giving structural concrete its compressive strength.
- Compliant to: Type A, 6H and 6K specifications.
