Concrete walkways are a popular choice for homeowners due to their durability and aesthetic appeal. However, one common issue that many people encounter is the rising of the concrete from the middle, often leading to an uneven surface that can be both unsightly and hazardous. In this article, we’ll explore the reasons behind this phenomenon, focusing on terms like concrete freeze heave and concrete driveway rise.

Understanding Concrete Walkway Issues

Concrete is a versatile material, but it is not impervious to environmental factors. Over time, various issues can arise, particularly when it comes to concrete walkways. If you’ve noticed your walkway rising from the middle, it’s essential to understand the underlying causes.

Common Causes of Concrete Rising

1. Soil Settlement
   • The soil beneath the concrete may settle unevenly, causing the slab to shift. If one side of the walkway has a firmer foundation than the other, it can lead to a noticeable rise in the middle.
2. Moisture Levels
   • Excess moisture can cause the soil to expand and contract. If the soil underneath the concrete becomes saturated with water, it can lead to upheaval. This is particularly common in areas with poor drainage.
3. Tree Roots
   • Nearby trees can have extensive root systems that may infiltrate the soil under the concrete. As these roots grow, they can push against the concrete, causing it to rise.
4. Concrete Freeze Heave
   • One of the most significant factors contributing to a rising walkway is concrete freeze heave. This occurs when moisture trapped in the soil freezes and expands during colder months. As the ice forms, it pushes the concrete upward, leading to a raised walkway.
5. Poor Installation
   • If the concrete was not poured correctly or if the subbase was not adequately prepared, it can lead to structural issues. Poor installation can result in air pockets and uneven settling over time.

The Impact of Rising Concrete

When a concrete walkway rises from the middle, it can pose several problems:
