How Intensive Snow Removal Can Damage Concrete Surface

07.12.2023

As winter blankets the landscape in a pristine layer of snow, property owners and municipalities engage in the vital task of snow removal to ensure safe and accessible surfaces. While the removal of snow is essential for safety and mobility, it is crucial to recognize that intensive snow removal methods can have unintended consequences, particularly on concrete surfaces. In this article, we will explore how aggressive snow removal practices can lead to damage in concrete structures and offer insights into alternative methods to mitigate potential harm.

The Impact of Intensive Snow Removal on Concrete:

  1. Abrasive Materials: One common method of snow removal involves the use of abrasive materials such as rock salt or calcium chloride. While these substances effectively melt snow and ice, they can also penetrate the porous surface of concrete. Over time, the repeated application of de-icing agents can contribute to the deterioration of the concrete, leading to cracks and weakening of the structure.
  2. Mechanical Removal: Snowplows and snow blowers are indispensable tools for clearing roads and walkways, but their use can pose a threat to concrete surfaces. The force exerted by snowplow blades and the impact of snow blowers can cause abrasion and surface damage. In particular, expansion joints and vulnerable areas of the concrete are at risk of chipping and cracking.
  3. Freeze-Thaw Cycle: Intensive snow removal can exacerbate the effects of the freeze-thaw cycle. When water seeps into cracks and pores in the concrete and subsequently freezes, it expands, putting pressure on the surrounding structure. The repeated freezing and thawing cycle can lead to the development of cracks, spalling, and overall deterioration of the concrete over time.

Mitigating Damage to Concrete During Snow Removal:

  1. Moderate Use of De-icing Agents: Instead of relying solely on aggressive de-icing agents, consider using them judiciously. Opt for environmentally friendly alternatives or use sand to provide traction on slippery surfaces without causing long-term harm to the concrete.
  2. Rubber Blades and Edges: When using snowplows, consider equipping them with rubber blades and edges. This helps minimize the impact on the concrete surface, reducing the risk of abrasion and damage.
  3. Proactive Maintenance: Regular inspections of concrete surfaces, especially after periods of intense snow removal, can help identify early signs of damage. Prompt repairs and the application of sealants can prevent further deterioration and extend the lifespan of the concrete.
  4. Alternative Snow Removal Methods: Explore alternative methods such as heated driveways and walkways, which can reduce the reliance on traditional snow removal techniques. While the initial investment may be higher, these solutions can be more sustainable and less damaging to concrete over time.

Intensive snow removal is a necessary and routine aspect of winter maintenance, but it is crucial to strike a balance between safety and the preservation of concrete surfaces. By adopting alternative methods and employing thoughtful snow removal practices, property owners and municipalities can ensure the longevity of their concrete structures while maintaining safe and accessible environments during the winter months.
