Concrete sidewalks are durable and attractive. To ensure your walkways made with this material last a long time, it is crucial to protect them from exposure to salt. Here are ways to care for your property and avoid damage during winter freezes and thaws.    

How to Prevent Salt Damage to Concrete Sidewalks

1. Use Alternatives to Rock Salt Deicers 

Rock salt itself does not cause concrete to deteriorate. However, when used as a deicer, it attracts moisture and lowers the freezing point of water. If the water freezes, the increased pressure of the ice expands the porous spaces of the concrete. When the water thaws, the larger spaces remain. As the freeze-thaw cycles continue during the winter, the results include concrete cracking and damage to the underlying materials. 

Using alternative deicers that do not contain salt protects the walkway from these damaging effects. Calcium chloride works better than salt, especially in temperatures between 0 and 30 degrees. 

2. Opt for All-Natural Solutions 

Sand is a popular natural solution to rock salt as a deicer, and it absorbs sunlight to speed snow and ice melting. Coffee grounds function similarly to sand and provide a surface that reduces slipping; they're also good as fertilizer.

Alfalfa meal is 100% natural, and its grainy texture provides traction. Sugar beet juice also reduces the melting point of snow and ice and is eco-friendly to concrete as well as plants and pets.

3. Apply a Repellent or Sealer

By applying a water-based repellent that penetrates the concrete walkway, you create a barrier that keeps out water and salt. The shield reduces the possibility of damage to the surface and supporting materials underneath, including rebar. An effective sealer keeps the water out of the tiny pores and extends the life of your sidewalks.
