Should You Salt Your Sidewalk Before It Snows?

Winter brings not only beautiful winter scenes but also the annual struggle with snow and ice. One common question among homeowners and property managers is whether to pre-treat their sidewalks with salt before the snow falls. This article explores the benefits and considerations of pre-treatment and how it can impact the efficiency of your snow removal efforts.

The Effectiveness of Pre-Treatment

Pre-treatment, also known as pre-treating, involves applying a salt or ice-melting compound to your sidewalk or driveway before the snow starts. This can be highly effective in reducing the amount of ice that forms and makes your snow removal tasks easier. The salt or ice-melting compound helps to lower the freezing point of water, preventing snow from bonding to surfaces and reducing the thickness of the ice layer that forms.

Pre-Treatment Methods

There are two main methods of pre-treating your sidewalk:

Brine Solution: Applied by trucks, a brine solution of salt and water is sprayed onto roads and sidewalks before the snowfall. This method is particularly effective for large-scale operations. The brine forms a protective layer on the surface, preventing the snow and ice from adhering. Granular Salt: This method involves spreading salt granules directly on the surface before the snow hits. It's a simpler and more DIY-friendly approach, making it suitable for smaller areas like driveways and sidewalks.

While both methods work, municipalities often opt for the brine solution due to its efficiency and effectiveness in preventing the snow and ice from bonding to surfaces.

Opting for Pre-Treatment

Deciding whether to pre-treat depends on several factors, including the amount of snow expected, the temperature, and the specific conditions of your area. If you live in a region that experiences heavy snowfall, pre-treating becomes increasingly important. Additionally, if you have multiple people using your sidewalks, pre-treatment ensures a safer walking environment, reducing the risk of slips and falls.

Considerations for Safety and Concrete

When pre-treating, it's crucial to consider the type of material your sidewalk or driveway is made of. While salt is effective for traction and melting snow, it can be harsh on concrete and new surfaces. Calcium-based alternatives, such as calcium chloride, are gentler and work well as a light base layer. They will melt the snow as it falls without damaging the concrete. Applying salt to new or chemically treated concrete can lead to flaking and other damage. Therefore, it's important to use the appropriate material for your specific needs.

Conclusion

Pre-treating your sidewalk with salt before a snowstorm can significantly reduce the amount of snow and ice you will have to deal with, making your snow removal tasks much easier. However, the actual effectiveness can vary based on the depth and duration of the snowfall as well as the temperature. Consider the local weather patterns and your specific circumstances to decide whether pre-treatment is the right approach for you.

Remember, the key is to plan ahead and think about the potential outcomes. Whether you choose to pre-treat or tackle the snow later, prioritize safety and practicality for the best results.
