How does it work?

Rock salt works by decreasing the freezing point of wetness on the road surface helping in accelerating the melting procedure, however before it can work it needs to be crushed & liquefied by approaching traffic otherwise it’s less reliable. Road gritters have to time it perfect too! If they grit too early, the rock salt arrive at a dry road and is typically blown away by the wind or traffic, if they grit too late, the road’s surface has already begun to freeze making it unsafe for people to drive. If they time it perfect, the salt is squashed on to the roads surface and it starts its melting procedure.

Different kinds of rock salt

There are several types of Liquid de icers, however the 2 that are most frequently used are white de-icing salt and brown rock salt. The latter is generally used to de-ice roads, driveways and walkways as it’s generally coarser whereas the white de-icing item is used to de-ice our schools, medical facilities, workplaces, walkways and entryway ways as it’s a cleaner option to brown salt.

Halite is a natural mineral which is found from underground. A small amount of calcium chloride is also present in it in addition to sodium chloride. Due to its hard nature it will not liquefy quickly in water. The primary benefit is that it is quickly available and cheaper. It is a family requirement. In cooking and cleaning functions we use this. In high snowfall that remains in cold weather conditions we use this salt. The frozen water melts if salt is sprayed on the roads. Just a small amount is needed as that alone is enough to deteriorate the ice. In some cases people will blend the salt with sand and spread it on the roads in order to avoid vehicle slides and accidents on icy roads.

Why is it so essential?

Gritting our roads and spreading it right also avoids countless accidents on our roads, freeways and walkways every year. According to a study, 1.3 million winter road accidents over the last 5 years have been triggered by icy conditions however with the assistance of the spreaders and salt providers these numbers intend to be lowered considerably.
