9 Tips to Protect Commercial Paving from Snow

How to Mitigate the Effects of Snow on Commercial Paving

1. Understand the Impact of the Freeze/Thaw Cycle

The freeze/thaw cycle is one of the biggest culprits behind winter pavement damage. When moisture enters small cracks in the pavement and freezes, it expands by up to 9%, forcing the cracks to grow larger. By addressing small issues early, a paving company can minimize repair costs and maintain the pavement’s structural integrity throughout the winter.

To mitigate this:

• Seal Small Cracks Early: A paving company can use crack-sealing techniques to stop water infiltration and prevent minor issues from growing into larger problems.

   

• Monitor Problem Areas: Property owners should keep an eye on low-lying or frequently wet areas where water can pool, as these spots are more susceptible to freezing.

   

• Ensure Proper Drainage: A well-designed drainage system can prevent water from accumulating on pavement surfaces and reduce the risk of repeated freeze/thaw damage.

2. Remove Snow and Ice Regularly and Promptly

Prompt snow removal is crucial to reducing damage to commercial pavements. When snow is left to sit, it can melt and seep into the surface, only to freeze again during cold snaps. This accelerates the freeze/thaw cycle and weakens the pavement.

Here’s how property owners can ensure effective snow removal:

• Schedule Regular Snow Removal: Work with a reputable paving company or snow removal service to clear snow promptly after every snowfall to keep surfaces safe.

   

• Use Proper Equipment: Avoid metal blades or shovels that can scrape the pavement and compromise sealants. Rubber-edged plows or blowers are safer and more efficient for protecting surfaces.

   

• Prevent Ice Build-Up: Use sand or de-icing alternatives (covered below) to minimize slippery surfaces and avoid accidents.

3. Use De-Icing Agents Sparingly and Correctly

While salt and de-icing agents help melt ice, they can also harm pavement surfaces and surrounding landscapes. Overuse can erode asphalt, stain concrete, and deteriorate the pavement’s structural integrity. By following proper de-icing practices, property owners can strike a balance between safety and pavement preservation throughout winter.

A professional paving company recommends the following:

• Use Safer Alternatives: Consider calcium chloride or magnesium chloride, which are less harsh than traditional rock salt and minimize long-term damage to asphalt.

   

• Apply in Moderation: Using too much de-icer does not improve effectiveness and may cause unnecessary chemical build-up that weakens the surface.

   

• Combine with Sand: Mixing de-icing agents with sand improves traction while reducing the amount of salt needed, offering both safety and protection for pavements.

4. Hire a Professional Snow Removal Service

Clearing snow seems simple, but improper snow removal techniques can worsen pavement damage. For example, using heavy plows or incorrect equipment can gouge the surface or remove protective sealants. 

The Asphalt Pavers Market is projected to grow at a Compound Annual Growth Rate (CAGR) of 5% from 2024 to 2029. This highlights the increasing demand for professional paving and snow removal services as businesses recognize the importance of maintaining durable, damage-free pavements.

Here’s why partnering with a snow removal service or paving company is beneficial:

• Expertise and Equipment: Professionals use specialized tools and vehicles that safely clear snow without harming the pavement.

   

• Timely Response: A reliable team ensures snow is removed quickly after storms, which prevents ice build-up and reduces liability risks for property owners.

   

• Preventative Solutions: Many paving companies offer winter maintenance packages that include snow removal alongside pavement repairs, helping to maintain the surface year-round.

5. Apply a Protective Sealant Before Winter

Sealcoating is a preventative measure that shields asphalt and concrete pavements from water, snow, and ice. A protective sealant fills minor cracks, creates a water-resistant barrier, and prevents surface wear. A trusted paving company recommends sealcoating in late summer or early fall to ensure the pavement is well-prepared to withstand winter’s challenges.

Benefits of sealcoating include:

• Enhanced Durability: A sealcoated surface is more resistant to vehicle wear, heavy snow loads, and exposure to de-icing chemicals. Sealants also stop water from seeping into cracks, reducing freeze/thaw damage and prolonging pavement life.

   

• Improved Appearance: Sealcoating restores the pavement’s smooth, black finish, enhancing its aesthetic appeal and curb value.

6. Address Damage as Soon as It Appears

Even minor cracks or potholes can worsen dramatically in winter. Small openings allow moisture to penetrate the pavement, which accelerates the damage. By addressing damage early, property owners not only save on costly repairs but also improve the safety and reliability of their commercial pavement.

To minimize this risk:

• Schedule Regular Inspections: Property owners should work with a paving company to inspect and identify cracks, potholes, or surface wear early.

   

• Patch Potholes Quickly: Temporary patches can prevent further damage until a permanent repair can be completed in warmer weather. This helps reduce the risks of larger issues.

7. Invest in Pavement Insulation for Added Protection

Pavement insulation reduces temperature fluctuations and protects surfaces from extreme freeze/thaw cycles. While this solution involves higher upfront costs, it reduces ongoing repair expenses and extends the pavement’s overall lifespan.

A paving company may recommend pavement insulation for:

• High-Traffic Areas: Commercial parking lots and driveways prone to significant winter wear can benefit from added insulation. Insulating these surfaces helps reduce stress from heavy vehicles and constant use, preventing cracks and surface degradation during the winter months.

   

• Cold Climates: Regions with long, harsh winters experience frequent freeze/thaw cycles, making insulation a wise investment. By stabilizing pavement temperatures, insulation minimizes expansion and contraction, which are the leading causes of winter-related structural damage.

   

• New Installations: Insulation is easier to incorporate during new pavement projects, offering long-term protection from winter-related damage. Installing insulation at the outset also ensures the pavement is better equipped to handle seasonal challenges, saving businesses money on future repairs.

8. Plan Asphalt Paving and Repairs Strategically

Timing is critical when it comes to asphalt paving and repairs. Cold temperatures and snow make winter a poor time for large-scale pavement projects. Instead, property owners should work with a paving company to schedule repairs during warmer months.

Tips for strategic planning include:

• Summer Repairs: Address cracks, potholes, and resurfacing projects in spring or summer to strengthen the pavement before winter sets in. Completing repairs during warmer months allows the materials to set and cure properly, ensuring long-lasting protection against heavy snow and freezing temperatures.

   

• Inspection Before Winter: Have a paving company perform a pre-winter assessment to identify vulnerabilities and fix them early. A thorough inspection ensures minor issues are addressed before they escalate, helping businesses avoid unexpected disruptions during the winter months.

9. Conduct a Post-Winter Inspection to Assess Damage

After winter ends, it’s essential to evaluate the pavement for damage caused by snow, ice, and freezing temperatures. An early inspection allows property owners to address issues before they escalate.

Steps to assess winter damage include:

• Check for Cracks and Potholes: Look for visible signs of deterioration, such as small cracks, potholes, or surface traveling. Early detection of these issues prevents them from worsening during temperature fluctuations or heavy traffic.

   

• Inspect Drainage Systems: Ensure water is draining properly to prevent pooling, which can accelerate pavement damage. Blocked or inefficient drainage systems can trap water, leading to freeze/thaw cycles that weaken the pavement’s foundation and surface structure.

   

• Consult a Paving Professional: A paving company can conduct a thorough inspection, recommend repairs, and implement long-term solutions. Their expertise ensures that repairs are tailored to the specific condition of the pavement. They can also apply solutions to enhance its durability and resilience against future weather challenges.
