Top 5 Most Common Foundation Issues

Soil Expansion and Contraction
Southeast Louisiana’s clay-rich soil is notorious for expanding when wet and contracting when dry. This continuous cycle can put a significant strain on foundations, leading to cracks and instability.

Flooding and Water Damage
Being close to the Gulf of Mexico, the area experiences heavy rainfall and occasional hurricanes. This results in flooding, which can cause foundation erosion, mold growth, and structural damage.

Subterranean Termite Damage
The humid climate of Southeast Louisiana is a perfect breeding ground for subterranean termites. These pests can severely weaken wooden foundation components, making the structure susceptible to collapse.

Poor Construction Techniques
Sometimes the foundation issues can be traced back to the building phase itself. Using subpar materials or improper construction techniques can result in a foundation that is not equipped to handle the environmental challenges of the region.

Tree Root Intrusion
The lush greenery of Southeast Louisiana is undoubtedly a sight to behold. However, the roots of large trees can sometimes intrude upon a building’s foundation, causing cracks and upheaval.


What are the signs of foundation issues?
Common signs include cracks in walls or floors, doors and windows that don’t close properly, uneven floors, and moisture in the basement or crawl space.

How can I prevent soil expansion and contraction from affecting my foundation?
Ensuring proper drainage around your property can help to maintain consistent soil moisture levels. Additionally, landscaping choices such as selecting plants that require less water can also mitigate the effects of soil expansion and contraction.

Is flood insurance necessary in Southeast Louisiana?
Given the region’s susceptibility to flooding, it is highly recommended to have flood insurance to protect your property from potential water damage.

How can I protect my foundation from termite damage?
Regular inspections and treatments by a pest control professional can help to protect your foundation from termites. Additionally, keeping the area around your foundation free of wood debris and ensuring proper drainage can reduce the likelihood of a termite infestation.

Can tree roots damage the foundation?
Yes, tree roots can cause damage by growing into the foundation. Planting trees a safe distance away from your home and considering the tree species and its root growth pattern are vital preventive measures.

Understanding the unique challenges that the environment in Southeast Louisiana presents is crucial for maintaining a strong foundation. By being aware of the top 5 most common foundation issues and taking preventative measures, you can ensure that your home or building remains safe and sturdy for years to come.
