Cracks in walls, uneven floors, and doors that won’t close properly are often signs of foundation heaving. This occurs when the soil beneath your home expands, pushing the foundation upward and causing structural damage. Foundation heaving is a serious issue, but understanding its causes and solutions can help you take the right steps to protect your home. Here’s what you need to know.
What Causes Foundation Heaving?
Foundation heaving occurs when the soil beneath your home expands and pushes upward, causing the foundation to lift. This movement can lead to a variety of structural problems, some of which can be quite severe if not addressed promptly. Several factors contribute to this phenomenon:
1. Expansive Soils
One of the most common causes of foundation heaving is expansive soils. Certain types of soil, such as clay, have a high capacity to absorb water. When these soils become saturated, they expand significantly, creating upward pressure on your foundation. Conversely, when the soil dries out, it contracts, leading to a cycle of expansion and contraction that can wreak havoc on your foundation.
2. Frost Heave
In colder climates, frost heave is a major culprit. This occurs when the water in the soil freezes, expands, and causes the ground to lift. As the ground thaws, the soil contracts, but the damage to your foundation can be permanent. Frost heave is particularly problematic because it can happen every winter, gradually worsening the condition of your foundation over time.
3. Poor Drainage
Inadequate drainage around your home can also lead to foundation heaving. When water isn’t properly directed away from your foundation, it can accumulate in the soil and cause it to swell. This issue is often exacerbated by clogged gutters, poor grading, or the absence of a proper drainage system, all of which can allow water to pool around your foundation.
4. Tree Roots
The roots of large trees near your home can extend under your foundation, seeking moisture. As they grow, they can displace the soil, causing it to heave. Additionally, when these roots absorb moisture from the soil, they can create pockets of dry soil that contract, contributing to further movement and instability.
5. Plumbing Leaks
A less obvious, but equally damaging cause of foundation heaving is plumbing leaks. A leak in your plumbing system can saturate the soil around your foundation, leading to soil expansion and, subsequently, foundation heaving. This is particularly concerning because plumbing leaks often go unnoticed until significant damage has already occurred.
How to Fix Foundation Heaving
Now that we’ve identified the common causes of foundation heaving, the next question is how to fix it. Addressing foundation heaving is a complex process that often requires professional intervention. Here’s what you can expect:
1. Soil Stabilization
One of the first steps in fixing foundation heaving is stabilizing the soil. This can be achieved through soil injections that reduce the soil’s ability to absorb water. In some cases, replacing the problematic soil with a more stable material may be necessary.
2. Improved Drainage
To prevent future heaving, it’s crucial to address any drainage issues around your home. This might involve regrading your yard to slope away from the foundation, installing French drains, or extending downspouts to ensure water is directed away from your home.
3. Foundation Underpinning
In severe cases, foundation underpinning might be necessary. This process involves reinforcing the foundation by extending it deeper into more stable soil or bedrock, thereby providing additional support. Methods like helical piers or steel push piers are often used in underpinning to stabilize the foundation permanently.
4. Repairing Cracks and Damage
Once the underlying cause of the heaving has been addressed, any cracks or structural damage to your foundation and home should be repaired. This might include sealing cracks in the foundation, leveling floors, and repairing any damage to walls or other parts of your home’s structure.
