Rock salt is used for de-icing sidewalks, car parks, driveways, steps and roads. This type of salt lowers the freezing point of water, causing it to stay liquid at colder temperatures. There are two types of rock salt: brown salt and white salt.

Brown rock salt is mined from underground salt deposits in Cheshire and is often used by councils, haulage yards and local authorities to give increased grip to icy roads. The brown colour comes from the impurities the salt contains as it comes straight from the mines.

White rock salt, sometimes searched for as “rock salt white”, is formed through the evaporation process from the sea. Sea water that evaporates in shallow beds leaves behind the remaining salt content in crystal form. This results in a cleaner and more hygienic option that will not leave any unwanted residue, unlike brown salt which leaves a muddy-looking residue.

This makes white rock salt better suited for public areas, such as hospitals, entrances to buildings, footpaths and schools where cleanliness is important. Our white rock salt complies with the British Standard BS3247:2011, which specifies the essential properties of salt for gritting.

Also called de-icing salt and gritting salt, rock salt is available in bulk bags and loose by the tonne. At Mainland Aggregates, we supply both these types of rock salt and can deliver both brown rock salt and white rock salt nationwide.
