Why Is My Driveway Peeling? The Truth About Winter Damage

When road salt lands on your driveway, it does two things:

1. It lowers the freezing point of water, allowing moisture to seep deeper into the concrete instead of freezing on the surface.
2. That moisture then refreezes inside the concrete, expanding and causing small surface fractures over time.

According to the American Concrete Institute (ACI), de-icing salts accelerate freeze-thaw damage by drawing additional water into the concrete pores, which increases internal pressure when frozen [ACI 201.2R-16].

Winter conditions with frequent freeze-thaw cycles make the problem worse. Some winters have more of these cycles than others, and studies show that climate change is increasing their frequency [National Oceanic and Atmospheric Administration (NOAA)]. More thawing and refreezing events mean greater potential for surface damage on concrete.

Richfield Concrete’s initial price estimates are very accurate, because we take special care to make certain we’ve taken all factors into consideration. Most final bills end up be the same as the estimate. However, changes in the project can change the total price. If the property owner decides to change something or we discover a condition that could not be known at the time of the estimate, the price may have to be adjusted. In such situations, we discuss the changes immediately with the property owner before proceeding with the project. Unlike some contractors, Richfield Concrete will never give you a final bill that contains surprises or hidden charges. We know you need an accurate price as soon as possible, and will always strive to make sure you have the correct price in advance.

The good news? No, this is not a structural problem. The peeling typically affects just the top 1/8 inch of your driveway, while the full slab is 4–5 inches thick. Concrete is most vulnerable in its first few years as it fully cures and hardens. As time passes, the surface becomes more resistant to these issues.

Even the Portland Cement Association (PCA) states that properly placed concrete maintains long-term durability despite surface wear in high-traffic or high-exposure areas [PCA Durability Guide].

Consider Sealing for Extra Protection

Sealing is not required, but it can add an extra layer of defense against moisture and de-icing salts. Richfield Concrete’s driveways already include integrated admixtures that improve moisture resistance. However, a high-quality penetrating sealer can further reduce moisture absorption and slow down surface wear. It won’t reverse existing damage, but it can help prevent new damage moving forward.

According to the National Ready Mixed Concrete Association (NRMCA), silane- and siloxane-based penetrating sealers are effective in reducing water and chloride intrusion without altering the concrete’s appearance [NRMCA Sealer Guide].

Avoid De-Icers—Use Sand Instead

De-icing salts worsen peeling by increasing moisture penetration. Instead, use sand for traction. Sand provides grip without chemical reactions. It’s a safer alternative for maintaining skid resistance.

The Concrete Pavement Institute (CPI) recommends avoiding salt-based de-icers, especially in the first 3–5 years of a new driveway, when the concrete is most susceptible to freeze-thaw damage [CPI Winter Maintenance Guide].

Keep Excess Salt Off Your Driveway

While road salt is unavoidable, minimizing buildup helps. Avoid parking in the same spot every day to reduce concentrated salt exposure. Brush off excess salt and slush from your vehicle before parking. Studies by the Federal Highway Administration (FHWA) show that repeated exposure to road salt significantly increases surface deterioration over time [FHWA Salt Impact Study].

Patching—An Option, But Not Always the Best One

Patching flaked areas is possible, but it comes with trade-offs. The patch material won’t perfectly match the original driveway in color and texture. In some cases, patches stand out more than the original flaking. Over time, as your driveway naturally wears, the appearance will blend better.

Mortar flaking is a surface issue, not a structural one. While it can be frustrating, it does not affect the long-term strength of your driveway. The best ways to protect your driveway include:

• Avoiding de-icers and using sand instead
• Minimizing road salt exposure from vehicles
• Sealing for extra protection, if desired

Your driveway was built to last, and as it fully cures and weathers naturally, any initial surface wear will become less noticeable. If you have additional questions or concerns, feel free to contact Richfield Concrete today!
