As much as 80% of salt and sand is thrown from the road and wasted. When applied before a storm, the chemicals are under the snow and ice preventing ice from forming a bond with the surface. If plowing is required, the work is made easier as only slush (rather than hard pack snow and ice) will remain. Salt is highly corrosive and harmful to vegetation. Liquid products can be much less harmful and easier maintenance means less damage, saving time and money.
