About our Brown Rock Salt

The rock salt we supply is mined in the UK and graded to BS3247:2011 (Highways Agency standards), which means it is crushed and screened to contain granuals between 1mm and 6mm in size.  It contains an anti caking agent to prevent the salt from forming lumps, this ensures it is free flowing and is therefore suitable for use in grit spreaders.

Full Specification & Rock Salt Material Data Sheet.

Brown rock salt has a dry density of approx 1.28 tonnes per m3 or 1.44 tonnes per m3 when wet.

These figures are at best a guide for use on highways with properly calibrated spreaders:
