Why Your Concrete May Shift During Winter (And What to Do About It)

Have you noticed your concrete surfaces rising during the colder months? This phenomenon, known as frost heave, occurs when the ground beneath the concrete freezes and expands, causing the surface to lift. While this movement is typically temporary, it’s essential to understand the process and when it might require professional attention.

What Causes Concrete to Heave?

Frost heave happens when moisture in the soil freezes, creating ice lenses that push the ground upward. Concrete surfaces, such as driveways, sidewalks, or patios, are particularly susceptible to this movement if they are laid over moisture-retaining soils.

Is It a Problem?

In most cases, the concrete will settle back into its original position once the ground thaws in spring. However, if the concrete does not return to its normal alignment, it could indicate underlying issues, such as:

• Poor soil drainage
• Compacted or unstable subgrade
• Repeated freeze-thaw cycles causing long-term damage

If left unresolved, these issues could lead to cracks, uneven surfaces, or permanent structural concerns.

When to Call an Expert

If your concrete remains elevated or you notice damage after the thawing season, it’s time to consult a professional. At TerraFirma, our experts can assess the situation and recommend solutions tailored to your needs, such as:

• Concrete Leveling: Using high-strength polymers to lift and stabilize the surface
• Drainage Improvements: Addressing water accumulation beneath the concrete
• Preventative Measures: Sealing the concrete to minimize moisture absorption

How to Prevent Future Heaving

Taking proactive steps can help minimize frost heave risks, including:

1. Improving Drainage: Ensure proper water runoff around your property.
2. Sealing Concrete Surfaces: Protect against moisture penetration with products like SealantPro.
3. Installing Insulation: Reduce frost depth by adding insulation layers below the concrete.
