Winter Concrete Care: Protecting Your Investment in Boston's Harsh Climate

Understanding Winter’s Impact on Concrete

Winter is harsh for concrete. When the temperature fluctuates, water inside the concrete expands and contracts, which can cause cracks. De-icing salts are used to melt ice, but when the salt comes into contact with the concrete and the steel rebar inside, it can corrode both. When there is a significant accumulation of snow or ice, prolonged exposure to moisture can deteriorate the surface. Lastly, plowing or using a shovel to remove snow can inadvertently damage the concrete surface.

Pre-Winter Protection

Before the first frost, apply a high-quality concrete sealer to create a protective barrier against moisture and chemicals.

Pro Tip: Select a breathable sealer that allows moisture vapor to escape from the concrete.

Clean and repair any existing damage. Fill all cracks and holes with an appropriate concrete patching compound. Ensure the surface is clean by removing dirt, oil, or other debris.

Why it matters: Existing damage will worsen much faster if you do not take action to fix it now.

Drainage and Water Management

Good drainage is essential for preventing water from accumulating under the concrete surface. Poor drainage can lead to standing water and increase the risk of freeze-thaw damage.

Quick Fix: Extend downspouts to move water further away from the concrete foundation or driveway.

Winter Maintenance Practices

• Traction: Instead of salt, sand or kitty litter can be used to improve traction on icy surfaces. If you must use a de-icing product, select one labeled as safe for use on concrete.
• Snow Removal: Remove snow from the concrete surface as quickly as possible. Use a plastic shovel or a snow blower to reduce the possibility of scratching the surface.

Remember: The longer snow remains on the concrete, the greater the chance of moisture entering the material.

Application-Specific Considerations

Driveways and Parking Areas

The best way to manage water runoff from driveways and parking areas is to use permeable concrete or install drainage channels. Additionally, consider applying a textured finish to improve traction.

Patios and Walkways

Protect decorative concrete on patios and walkways from severe weather by covering it with breathable tarps. Additionally, install adequate lighting to help identify slippery areas.

Foundations

To avoid water accumulation near the foundation, ensure gutters and downspouts are cleared of leaves and debris. Maintain a slight incline on the ground sloping away from the foundation to allow water to drain properly.

When to Call a Professional

There are times when it makes sense to call in a professional for winter concrete care, including:

• The appearance of large cracks or uneven settling.
• Signs of concrete spalling or flaking.
• The need for an advanced drainage system installation.
• The application of a commercial-grade sealer.
