Pretreatment to Prevent Icing
December 9, 2018
At Scotts Exterior Maintenance, we strive to stop the ice before the storm begins. Our company is introducing an anti-icing method to help keep commercial and residential pavement safe when freezing drizzle or light snow is predicted.
Crews are applying liquid anti-icing to improve winter driving and walking conditions. Anit-icing is most often doen the day before a light freezing drizzle or light to moderate snow events. It is useful at specific pavement temperatures when a bond between ice and the pavment is most likely.
Anti-icing is a tool to maintain better pavement conditions, but it does not replace road salt, especially during freezing rain or blowing and heavy snow events.
Goal of Anti-icing
The goal of anti-icing is to prevent or reduce the bond of snow and ice to the pavement, reducing the need for granular deicing products to break that bond after the event. This is done by spraying salt brine on the pavement befdore the winter event; the brine dries on the surface and then is rehydrated when the precipitation begins.
Liquid application make it possible to apply a small amout of salt to the pavement reducing the environmental impact. With a smaller bond between the snow and the pavement, plows can remove more snow from the road and apply less salt after plowing. Additional benefits include increased traction on brine - treated pavements for longer periods of time, especially in light snow events.
Our salt mixed in 23% water solution is the most commonly used anti-icing, additions may include calcium or magnesium chloride to lower the practical working temperature, or organic additives like beet juice or corn syrup to reduce corrosiveness and increase adhesion to the road surface. At Scotts, we strive to make our anti-icing the most enviromentally safe and cost effective practice in winter maintenance. It requires about 1/4 the material to produce.
Where It's Used
Scotts Exterior Maintenance are using anti-icing treatments on all commercial and residental contracts. Commercial lots can be treated around the enterence areas along with the parking lot area. Residental contracts can receive treament on driveways, sidewalks, and any other pavement areas that are needed.
