Understanding Different Types of Rock Salt
Rock salt, also known as sodium chloride, is commonly used for de-icing roads, driveways, sidewalks, and other outdoor surfaces during the winter months. However, there are various forms of rock salt, each with its own set of characteristics. As a landscape contractor, knowing the difference between these options will help you select the best rock salt for each situation.
Bulk Rock Salt – This is the most common and affordable option. Bulk rock salt is highly effective for melting ice and snow, especially on large surfaces like parking lots and driveways. It’s widely available and easy to apply, but it can be harsh on delicate surfaces such as plantings and concrete. In our area, where temperatures can fluctuate dramatically, bulk rock salt is a dependable choice for large-scale winter maintenance projects.
Calcium Chloride – This is another popular de-icing product that is more effective in extremely cold temperatures than regular rock salt. Calcium chloride can melt ice even at temperatures as low as -25°F, which is especially important during the colder months of winter. While calcium chloride is faster and more effective than traditional rock salt, it can be more expensive. Its use is ideal for smaller, high-priority areas where protection is paramount, such as walkways and stairs.
Magnesium Chloride – Similar to calcium chloride, magnesium chloride is effective at lower temperatures and is less damaging to plantings and concrete surfaces. It’s a great option for contractors concerned with environmental impact, as it’s less harmful to planting life and hardscapes. While it may cost more than traditional rock salt, the benefits of using magnesium chloride in areas with delicate landscaping are substantial, especially when looking to minimize damage to the surrounding greenery.
Sodium Chloride Blends – Sometimes, a mixture of sodium chloride with other chemicals such as calcium or magnesium chloride is the most effective solution. These blends offer the benefits of enhanced de-icing performance without the potential drawbacks of using a single product. By choosing a blend, contractors can tailor their winter maintenance to suit the specific needs of each property, reducing damage to surfaces while still achieving excellent ice-melting results.

How to Choose the Right Rock Salt for Your Project
Understanding the types of rock salt available is only part of the equation. Selecting the right product for each job requires careful consideration of several factors specific to the area, including weather patterns, surface types, and the long-term impact of the de-icing material.
1. Temperature Range—The most important factor in selecting the right rock salt is the temperature range. Our area experiences a mix of winter temperatures, with cold nights and occasional snowfalls. If temperatures regularly drop below 20°F, using bulk rock salt may not be as effective. In these cases, calcium chloride or magnesium chloride would be a better choice, as they perform better in low temperatures.
2. Surface Types—The surfaces that need to be treated are also crucial factors. While traditional rock salt is effective on asphalt and concrete, it can be harsh on certain surfaces like brick, pavers, or plantings. For contractors working with delicate landscaping features, using blends or magnesium chloride can help prevent damage to these surfaces. For commercial properties, bulk rock salt may be ideal for parking lots and roads, while using gentler products for walkways and entranceways will ensure it maintains the overall aesthetic and protection.
3. Environmental Impact—The impact of rock salt on the environment is another factor to keep in mind. While traditional rock salt is effective and affordable, it can be harmful to plantings, animals, and water sources. If your projects involve landscaped areas with significant plantings, magnesium chloride or blends might be a more sustainable and eco-friendly option. These alternatives cause less harm to the environment and can be just as effective at keeping walkways accessible.
4. Application and Efficiency—Another consideration is the ease of application and overall efficiency of the rock salt. Some materials, such as bulk rock salt, may need to be applied in larger quantities to achieve the same results as more concentrated products like calcium chloride. Understanding the application rate and choosing products that can be spread easily across large areas will help streamline your operations and maximize efficiency during the winter months.
