For strip mall owners and commercial property managers in Green Bay, the changing seasons present a clear challenge: how do you keep your facilities safe and looking great throughout the year? While the parking lot is often the focus, the sidewalks—the pathways your customers use every single day—are equally, if not more, critical.
When winter hits, the combination of aggressive snow removal and relentless freeze-thaw cycles turns minor concrete issues into major liabilities. At American Pavement Solutions, we understand that delaying repairs until after the winter thaw is a common—and costly—mistake.
Here is why you should prioritize concrete sidewalk repair and maintenance before the first snowfall.
The Perfect Storm: Snow, Salt, and Your Concrete
Wisconsin winters are especially tough on exposed concrete. Once temperatures drop, your sidewalks become vulnerable to a series of destructive forces that are sped up by the very things you do to keep them safe.
The Dangers of Freeze-Thaw Cycles
Concrete is porous, meaning water can seep in. This is where the damage begins:
- Expansion and Cracking: Water that enters the concrete freezes, expands, and causes the surface to break apart. This cycle of freezing and thawing is a standard condition in Green Bay winters, and it turns small, manageable cracks into significant structural problems.
- Spalling Escalation: Small cracks allow water to reach the steel reinforcements inside the slab. The resulting rust expands, forcing the surrounding concrete to crack and spall (chip or flake away). This is one of the most visible signs of winter damage, often seen on walkways and curbs.
How De-Icing Chemicals Accelerate Damage
We use de-icing salts and chemicals to keep surfaces safe, but they pose their own threat to your concrete sidewalks.
- Chemical Deterioration: Salts and harsh deicers chemically deteriorate the concrete surface over time. The chemicals can block water and de-icing products from penetrating the surface, and if you use non-concrete-safe products, the degradation is sped up significantly.
- Our Recommendation: Instead of corrosive rock salt, use non-corrosive ice melts or sand to manage snow and ice on concrete.
The Snow Plow Problem: Turning Flaws into Hazards
Minor cracks might be easy to ignore in October, but they become instant liabilities once the snow removal crew arrives.
- Exposing Vulnerabilities: A heavy snow plow blade or a metal shovel—which we generally advise against using on any pavement —can catch on an uneven edge, a small pothole, or an already-spalled section. This impact tears away existing weak points, instantly escalating a minor issue into a large, unsafe hole.
- Preventing Water Runoff: Plowed snow piles can direct water toward the sidewalk edges, contributing to pooling. Proper drainage is essential to keep water away from your concrete, preventing pooling that can weaken the surface and create hazardous conditions.
The Cost of Waiting: Liability vs. Longevity
Why risk it? Waiting until spring to address a spalled section or a large crack will cost you far more than a timely repair.
| The Danger of Delaying Repairs | The Benefit of Pre-Winter Action |
| Increased Liability: Spalled concrete creates significant tripping hazards for customers and staff. A slip-and-fall lawsuit on a clearly damaged surface is a serious financial threat. | Enhanced Safety: Addressing damage early helps maintain a smooth and safe surface for pedestrians, mitigating liability. |
| Escalating Repair Costs: A minor crack that costs a few dollars to seal in the fall can turn into a massive pothole or a deeply spalled area requiring extensive, costly concrete spall repair come spring. | Escalating Repair Costs: A minor crack that costs a few dollars to seal in the fall can develop into a massive pothole or a deeply spalled area, requiring extensive and costly concrete spall repair come spring. |
| Structural Damage: Once water penetrates, it causes internal damage that leads to structural weakening. This compromises the long-term durability of the entire concrete section. | Cost Savings: Preventive maintenance is far less expensive than complete replacement or major structural repair. |
Steps to Take Before Winter
Proactive maintenance keeps your concrete durable and visually appealing, especially in Green Bay’s challenging climate.
- Inspect Thoroughly: Inspect your concrete annually for cracks, discoloration, or uneven settling.
- Repair and Seal Cracks: Seal small cracks as soon as they appear to prevent water from seeping in and causing further damage. Repairs are best done during moderate temperatures with freeze-thaw-resistant products.
- Address Spalling: The timely repair of concrete spalls is critical—not just for appearance, but also for safety and long-term durability.
- Seal and Protect: Apply a breathable concrete sealer to block water and deicing chemicals from penetrating the surface. Resealing should be done every 2-3 years.
When your sidewalks show signs of spalling, don’t wait for the damage to spread. At American Pavement Solutions, we specialize in concrete spall repair for commercial properties throughout Green Bay and the Upper Midwest.
