Deicing Your Driveway the ECO Friendly Way

Did You Know Deicers Can Be Environmentally Harmful?

Depending on which solution is used, concerns might include it washing down into water stores, damaging plants, creating air particulates, or being harmful to animals.  It can also cause damage to home fixtures like wooden steps and may damage asphalt.  Even storing deicing solutions is a careful business, since large amounts can leach into soil and seriously affect nearby waterways.

Use Deicers Sparingly

In those rare cases when more powerful deicing solutions are needed, it’s important to shovel and plow first, and then use the least toxic option that's still effective.  Salt and sand are the most cost-effective, but calcium magnesium acetate (CMA) is also relatively inexpensive and benign.  Potassium acetate (KA) is another fairly benign option that also works at colder temperatures than salt or CMA.

An Environmentally Friendly Mix

The best option in many cases is to use a mix of various deicing agents.  At Wolf Paving, we prefer to use a mix of sand and salt, in ratios of 8:1, 4:1, or 1:1 as appropriate.  No solution is perfect, but we find this is the best for melting, improving traction, and having the minimal possible impact on the environment.
