Interlocking pavers are a durable and visually appealing choice for outdoor spaces, but winter weather can take a toll on their longevity. Homeowners in colder regions, especially those with harsh winters, need to take proactive steps to protect their paved surfaces from freezing temperatures, snow, and ice. If you have interlock pavers in Durham Region, ensuring proper winterization will help prevent costly repairs and maintain their pristine condition year after year.
Why Winterization Matters?
Cold weather, especially in regions with frequent freeze-thaw cycles, can cause significant damage to interlocking pavers. When water seeps into the joints and freezes, it expands, leading to surface heaving, shifting, and cracking. Salt and deicing chemicals can also accelerate wear and discoloration, while heavy snow accumulation can contribute to erosion and structural instability. Taking the right precautions before winter arrives will help prevent these issues and extend the life of your paved areas.
Step-by-Step Guide to Winterizing Your Interlocking Pavers
- Clean the Surface Thoroughly: Before winter sets in, remove all dirt, debris, and organic matter from the paver surface. Fallen leaves, twigs, and soil buildup can trap moisture, leading to mold growth and staining. Use a broom or a pressure washer to clear the area, paying special attention to the joints between the pavers. If there are oil stains or mildew spots, consider using a paver-friendly cleaner to eliminate them.
- Inspect for Damage and Make Repairs: Cracks, loose pavers, or sunken areas should be addressed before the first snowfall. Minor damage can worsen during the winter, making repairs more expensive in the spring. Check for uneven surfaces, shifting pavers, and missing joint sand. Replace any broken pavers and relevel sections where necessary.
- Reapply Joint Sand: Polymeric sand is essential for maintaining the stability of interlocking pavers. Over time, wind, rain, and foot traffic can wash away the sand from the joints, creating gaps that allow water to seep in. Reapply fresh polymeric sand to fill the joints and prevent water infiltration. Once applied, use a compactor to set the sand, then mist it lightly with water to activate the binding agents.
- Seal the Pavers: Sealing interlocking pavers creates a protective barrier against moisture, salt, and stains. Choose a high-quality, breathable sealant designed for pavers to enhance durability without trapping moisture underneath. A properly sealed surface repels water, minimizes freeze-thaw damage, and keeps the pavers looking vibrant. Apply the sealant according to the manufacturer’s instructions, ensuring even coverage for optimal results.
- Ensure Proper Drainage: Standing water is one of the biggest threats to paver longevity. Before winter, check that your paver installation has adequate drainage. If you notice pooling water, consider adding a slight slope or improving the base material to direct runoff away from the surface. French drains or additional gravel layers can also help prevent water accumulation.
- Avoid Harsh Deicing Products: Rock salt (sodium chloride) and chemical deicers can cause paver surfaces to deteriorate over time. These substances can lead to efflorescence (white residue), discoloration, and weakening of the material. Instead, opt for calcium magnesium acetate or sand for traction, which are safer alternatives that won’t damage your pavers.
- Shovel with Caution: Using metal shovels or snowplows with sharp blades can scratch or chip the surface of interlocking pavers. To prevent damage, use a plastic shovel or a snowblower with rubber blades. If you must use a metal shovel, lift rather than scrape to avoid unnecessary wear.
- Monitor and Maintain Throughout Winter: Winterization doesn’t end once the snow falls. Regularly inspect your paved areas to remove excess snow and ice buildup. If you notice any signs of shifting or damage, address them as soon as possible to prevent worsening conditions.
- Common Mistakes to Avoid
- Skipping the Sealing Process – Unsealed pavers are more vulnerable to moisture damage, stains, and wear.
- Using Excessive Deicers – Overuse of salt-based deicers can lead to long-term surface damage.
- Ignoring Small Repairs – Minor cracks and loose pavers can become major problems if left unaddressed before winter.
- Neglecting Drainage Issues – Poor drainage can accelerate erosion and structural instability.
When to Call a Professional
While many homeowners can handle basic winterization steps, there are situations where professional assistance is beneficial.
