What is Anti-icing?

Anti-icing is a snow and ice control measure to prevent a strong bond between frozen precipitation or frost and a pavement surface by timely application of a chemical freezing point depressant. Proactive approach.

What is Deicing?

De-icing is a measure where a deicer is applied to the top of an accumulation of snow, ice or frost that is already bonded or formed to the pavement surface. Reactive approach.

Why anti-icing over deicing?

• Most liquid deicers usually stay where you put them
• Typically less chemical is used
• Can be applied before the storm or early in the storm
• Service levels are raised
• Maintenance costs are lower
• Reduced environmental impact

Anti-icing chemicals lower the freeze point temperature of water, depending on the percentage of chemical in solution.

Key to succesfull snow and ice control

• Both anti-icing and deicing are needed for effective winter storm management.
• You need a tool box approach for choosing the deicer and method of application.
• Snow and ice control is an art combined with science.
• Purchase price of material is not the only cost consideration.
• Long lasting effect
• Snow more easily removed
• Lower chemical usage
• Plowing required
• Lower equipment maintenance costs
