As winter approaches, preparing for icy conditions becomes essential, especially when it comes to keeping driveways, sidewalks, car parks, and roads safe. One of the best ways to prevent ice from forming and to maintain safe surfaces during freezing temperatures is by using rock salt. Investing in rock salt can make a significant difference in reducing slip hazards and keeping your property accessible throughout the colder months. 

  
How Does Rock Salt Work? 

Rock salt works by lowering the freezing point of water, preventing ice from forming on surfaces such as roads, pavements, and driveways. By spreading rock salt over icy areas, you effectively melt the ice and create a safer, non-slippery surface. It’s an essential tool for anyone responsible for maintaining public or private spaces during the winter months. 

  
The Two Types of Rock Salt 

When considering rock salt for winter, there are two main types available: brown rock salt and white rock salt. Each type has its own benefits, making them suitable for different environments. 

  
1. Brown Rock Salt 

Brown rock salt is often used for industrial and large-scale de-icing needs, such as on roads, in car parks, or haulage yards. This type of salt is mined from underground salt deposits, like those in Cheshire, and is recognised by its distinct brown colour, which comes from natural impurities. These impurities help provide better grip on icy surfaces, making brown rock salt especially useful in high-traffic areas where increased traction is needed. However, the residue left behind by brown rock salt can be a bit messy, often leaving a muddy-looking residue after use. 

  
2. White Rock Salt 

White rock salt, on the other hand, is harvested after sea water that evaporates in shallow beds which leaves behind the remaining salt content in crystal form. It’s a purer type of salt, making it a cleaner option that won’t leave behind unwanted residue. This makes white rock salt the ideal choice for areas where cleanliness is a priority, such as hospitals, schools, and entrances to buildings. It’s perfect for residential use as well, keeping driveways and footpaths safe without the mess associated with brown salt.

Why Invest in Rock Salt? 

Investing in rock salt is a practical choice for anyone living in areas prone to winter weather. Ice can form quickly, even in mild winter conditions, and having rock salt on hand can prevent accidents and injuries. Whether you’re maintaining a commercial property or simply want to keep your driveway safe, rock salt is a reliable and cost-effective solution.
