Before You Sprinkle That Ice Melt… Read This First!

As temperatures drop and winter weather sets in, homeowners start preparing for icy sidewalks, driveways, and patios. While keeping your walkways safe is important, many don’t realize that the way you melt ice can actually cause serious damage to your concrete surfaces. At first glance, it might seem like ice melt is your best friend—but in reality, it can be one of concrete’s worst enemies.

How Freezing Weather Affects Concrete

Concrete is a durable material, but it’s also porous. That means it absorbs small amounts of water. When temperatures fall below freezing, this water expands as it turns to ice—creating internal pressure that can cause cracking, flaking, and spalling over time. Repeated freeze-thaw cycles take a toll, especially on older or unsealed concrete. Once those cracks form, they allow even more moisture to enter, accelerating the damage each winter.

The Problem with Ice Melt Products

Most traditional ice melt products contain rock salt (sodium chloride) or calcium chloride, which can speed up ice melting—but at a cost. These chemicals penetrate the surface of the concrete, and when they refreeze, they expand beneath the surface, leading to scaling and surface deterioration. Additionally, salt-based melts can harm landscaping, pets, and metal surfaces nearby, compounding the long-term damage.

Safer Alternatives for Concrete

If you want to protect both your family and your concrete, consider using concrete-safe alternatives this winter. Products containing calcium magnesium acetate (CMA) or potassium chloride are far less corrosive and much gentler on concrete surfaces.

Another simple and cost-effective option? Sand or kitty litter. While they won’t melt ice, they provide traction and help prevent slips without damaging your walkways or driveways.

Pro Tip from Your Home Inspector

To extend the life of your concrete:

• Seal your flatwork before winter hits to help prevent water absorption.

• Avoid de-icers with salt or chloride compounds.

• Clean up ice melt residue in the spring to prevent long-term damage.

• Inspect your concrete annually for cracks or spalling and repair early to prevent further deterioration.

Freezing temperatures are tough on homes, but with the right care and products, your concrete can withstand many winters ahead. Protect your investment this season by being mindful of what you use on your sidewalks, patios, and driveways.
