All deicing compounds, including road salt, do not work in extremely cold temperatures. Sand can be broadcast over icy surfaces to improve traction when deicing agents are ineffective. The use of sand may require additional sweeping and cleaning maintenance.
Minimize the use of deicing chemicals during the first two years of concrete curing. Properly designed, air-entrained and cured concrete is required to provide a durable concrete structural system, but concrete curing is an ongoing process. During this initial two-year time period, it is recommend to follow method 1 & 6 only as noted below.
After the first two years of concrete curing, deicing agents may be used as indicated below. There are also anti-icing agents such as Potassium Acetate available on the market which may be utilized in preparation for an upcoming snow/ice event. Anti-icing agents will prevent adhesion of snow/ice to concrete.
Recommended deicing measures, in order of decreasing preference, are:
