Milwaukee winters can be brutal. Not only does the snow and ice pose a danger to drivers, but frozen sidewalks can be unsafe for pedestrians too if not taken care of. Contact a Milwaukee, Wisconsin concrete contractor and have him apply an ice melting compound. The most commonly used product is sodium chloride, also known as rock salt. It’s very effective but has two downsides: it doesn’t melt ice at temperatures below 20 degrees Fahrenheit and it’s corrosive to steel, trees and shrubs. Calcium chloride is another substance that Milwaukee concrete companies can apply to ice. It can work at temperatures as low as minus 25 degrees Fahrenheit, but also damages lawns and vegetation.
