Does Snow Damage Your Driveway?

Concrete Driveways

Concrete driveways are durable but vulnerable to winter’s harsh conditions. Like asphalt, they can suffer from freeze-thaw damage, which can cause spalling—flaking or chipping of the surface. De-icing salts are especially harmful to concrete, as they cause chemical reactions that weaken the material.

To lessen damage to concrete, consider the following precautions:

• Apply a high-quality sealant designed for concrete.
• Avoid using traditional rock salt; opt for non-corrosive alternatives.
• Remove snow regularly to minimize melting and refreezing.

Paver and Brick Driveways

Concrete paver and brick paver driveways are generally more resilient to winter weather. The paver installation method has an interlocking structure that allows for better water drainage; however, these surfaces aren't immune to damage. The gaps between pavers can allow water to pool, freeze, and shift the pavers out of place. Additionally, the use of heavy snow removal equipment can dislodge the bricks or do damage to pavers.

Tips for protecting paver and brick driveways:

• Just like a paver patio, regularly sweep sand or polymeric jointing material into the gaps to keep them stable.
• Use rubber-edged snow shovels or snowblowers with plastic blades to avoid damage.
• Stop with the excessive use of de-icing salts; it can erode the material.

Unpaved Stone Driveways

Unpaved stone driveways have their own set of challenges in snowy conditions. Snow and ice can compact the stones, making an uneven surface and difficult to navigate. Plows are a problem, too. Despite the operator's best efforts, snow plows can push stones into your yard or disrupt the surface entirely.

Maintenance tips for unpaved stone driveways:

• Level the surface before winter to reduce pooling water.
• Plow or snow blow with care using a raised blade to avoid disturbing the stones.
• Add fresh gravel in the spring to replace displaced material.

Steps to Protect Your Driveway During Winter

Taking preventative measures can extend the lifespan of your driveway. Here are some quick steps to minimize potential damage:

• Seal cracks and surfaces before the first snowfall to prevent water infiltration.
• Shovel snow promptly and avoid letting it accumulate.
• Use non-corrosive de-icers such as sand or calcium magnesium acetate instead of rock salt.
• Inspect your driveway periodically for signs of damage or wear.
• Hire professionals for snow removal if you have a delicate surface like concrete pavers or paver bricks.

FAQ

Does snow removal equipment damage driveways?

Yes, snow removal equipment like plows and shovels can cause significant wear and tear if used improperly. Metal shovels and plow blades can scratch or chip asphalt and concrete surfaces, while improper plowing with heavy equipment can dislodge pavers or compact stone driveways. To minimize damage, use rubber or plastic-tipped tools, and consider hiring professionals familiar with your driveway material who can do a proper plowing job.

What is the best way to protect my driveway from winter damage?

Preventing damage starts with preparation. Sealing the surface, repairing cracks, and choosing appropriate de-icing agents are all good ways to protect your driveway. Regular maintenance, such as clearing snow promptly and inspecting for damage, can also help. For unpaved stone driveways, leveling and adding fresh gravel are important seasonal tasks.
