How Much Rock Salt Do I Need?

This seemingly “simple” question raises a whole host of critical considerations, including the size of the surface you are treating, the frequency of rock salt application required, and your region's climate. So, where should you begin? 

A good starting place would be determining how many square feet you need to treat.

• Are you treating a parking lot, driveway, or property of a similar size? If you are dealing with a standard parking lot (which can accommodate about 20 to 25 cars), it is likely about 10,000 square feet.
• Meanwhile, the average driveway is approximately 1,000 square feet.
• Thankfully, if you are a snow-removal contractor, property manager, landscaper, or facility operator (contact us for wholesale bulk rock salt), this is where the math gets easy. Standard practice for you would be buying rock salt by the ton. This rule means that one order of rock salt would cover approximately 16,000 to 20,000 square feet, depending on the rate, depth of application, and conditions. 
  
  Nevertheless, if you live in a colder climate characterized by frequent freeze-thaw cycles or if ice or snow has already hit before the application of the rock salt, you will likely have to add even more rock salt to the surface you are treating. Therefore, a wise practice would be to purchase more rock salt than the calculated amount for a particular project. Plus, if you store that rock salt in a dry, covered place, it will still be usable for the next season!
