Understanding Salt Brine

While we are in the midst of the summer season, the Greenscape teams are already beginning to prepare for the upcoming winter. Greenscape regularly meets with clients to understand their true objectives, and ways to improve our snow service. The conversation of late has largely been centered around the introduction of Salt Brine as an effective tool to use in combatting winter storms. We hope the following information helps to provide valuable insight into the effectiveness and limitations of Salt Brine.

​What Is Salt Brine?
​
Salt Brine is an effective liquid solution for fighting snow and ice on roadways, parking lots and walkway. Salt Brine is made in tanks circulating specific amounts of rock salt and water until the concentration of salt in water reaches a specific percentage. The solution is then pumped into holding tanks in preparation for use. Other elements such as calcium or magnesium may be added to address specific temperature ranges of a storm to increase the effectiveness of the application. 

Salt Brine is used to pre-treat surface areas in anticipation of wintry conditions. If applied before a winter storm, Salt Brine will begin working as soon as the first snowflake falls and will help delay the accumulation of snow and ice on the pavement. While granular salt alone lowers the freezing temperature of ice, it must be wet for the chemical reaction to take place and melting to begin. Putting dry salt down means you must wait for pre-melting to begin - Salt brine jumpstarts this process. 

​When Is Salt Brine Used?
​
One of the major benefits of Salt Brine is the ability to apply Brine up to 48 hours in advance of a storm. The peace of mind knowing that your property is treated and prepared for an event is substantial. Lots of things can go wrong before a snow storm: forecast changes, equipment breaks down, traffic etc. Knowing that your property has been pretreated is extremely re-assuring when facing these variable factors. Despite the many positives of Salt Brine, there are certain weather conditions in which the application of Brine is not advisable. Contractors should monitor weather forecasts and record pavement temperatures to correctly diagnose the optimum application times. 

When Is Salt Brine Not Advisable? 

• If snow/ice has already bonded to pavement
• Painted surfaces and crosswalks
• In extreme cold
• Storm begins as rain
• Pavement temperatures are above freezing

 
 
How Is Salt Brine Applied?

Salt Brine is applied in specially designed trucks with holding tanks and spray bars. The spray bars apply several streams of brine onto the roads. Sidewalk units can spray brine from a hand-held wand or powered spray unit. These units allow the applicator to control the amount of material applied based on the conditions present or forecasted.

Is Salt Brine Better For The Environment?

Salt applications to roads and paved areas have a major impact on our environment.  Salt naturally migrates into lakes and streams and can have a major impact on your landscape plant material. Salt corrosion is one of the leading causes of road and bridge deterioration in Northern climates.   Brine applications to an area use  ¼ of the salt that would be applied in a similar application. In addition, because it is directly applied to the surface there is no scatter or bounce into unintended areas.
 
 
What Are Some Of The Other Advantages Of Salt Brine?

• Anti-icing allows the road surfaces to be cleaned quicker and cleaner, resulting in fewer accidents and delays
• Using Liquid Brine starts the melting process faster than rock salt
• Brine doesn’t bounce or blow off the road, impacting other areas or wasting product
• If the storm is delayed the Brine remains, and is ready when the storm begins
• The amount of salt applied is significantly reduced to walkways and roadways

 

Why Doesn’t Everyone Use Salt Brine?

The main reason that Salt Brine use has not been widespread is that there is a significant upfront investment in the equipment and training needed. Most customers are paying for De-icing on a per application basis, and there is no incentive to the contractor to make a switch.

 
Why Do Snow Contractors Over Salt?
​

• Liabilities: Slip and fall claims related to winter service account for more lawsuits than any other, except auto. 
• Contractors will over salt to protect themselves from litigation
• Equipment to start up Salt Brine operation is expensive
