9 Common Causes Of Foundation Cracks

Foundation cracks are a common yet concerning issue in homes and buildings, often resulting from a variety of underlying causes.

One primary cause is soil movement beneath the foundation. This can occur due to soil expansion and contraction as moisture levels change, leading to shifting and settling of the ground. While this may be the most common, other issues also contribute to the problem.

This article breaks down all the causes crucial for diagnosing the severity of the cracks and determining the appropriate remedial measures.

Understanding the Causes of Foundation Cracks

1. Poor Foundation Construction

Using the right materials during foundation construction is important to prevent foundation problems. If quality building materials are not used, the entire foundation is compromised and could fail.

2. Construction: Soil Condition

Soil testing is always recommended before building a home. Most homes in the U.S. are built in areas where some clay content is found and in most cases, there is a large amount of clay in the soil resulting in seasonal movement. Soil compaction is also vital in preventing foundation cracks. The uppermost layer of the soil provides the bearing capacity for a stable foundation. Failure to compact the soil during the grading process will subject the foundation to settlement as the supporting soil consolidates.

3. Expansive, Heaving, or Consolidating Soil

The type of soil your house was built on affects the stability of your foundation. When moisture levels in the soil are too high, the clay soil expands, causing upheaval and pushing your foundation in an upward direction. When the soil is too dry, the soil settles, pulling away from your foundation when it dries out.

4. Flood

Too much water can also cause foundation cracks. Water intrusion is possible during periods of heavy downpours from a storm or when snow melts in the spring. An adequate drainage system is needed.

5. Plumbing Leaks

Oftentimes water from plumbing leaks can cause significant foundation problems. Even a small leak left unnoticed can cause the foundation to move or shift.

6. Gutters & Downspouts

Gutters need to be clean from leaves and downspouts have to be pointed away from your home. Checking the gutters regularly also helps to make sure there are no clogs or leaks that might cause the water to overflow near the foundation.

7. Inadequate Drainage System

Improper drainage is one of the leading causes of foundation failure. Water leaking into your basement or crawl space may lead your foundation to shift. Oftentimes the problem goes unnoticed until cracks start to develop. The foundation will continue to shift until it is fixed.

8. Evaporation

Hot weather and a dry wind can dry out the soil, causing settling and soil sinking. When this happens, cracks in the foundation may appear throughout the structure.

9. Large Trees

Growing a large tree next to your house may look good, but may not be a good idea. When the roots extend under or next to your foundation, the moisture in the soil that actually keeps the soil stable will be taken away by the tree since it consumes water regularly, especially during drought.
