North Carolina is a beautiful state with a diverse climate, ranging from the coastal plains to the Appalachian Mountains. However, this climate diversity can create challenges for building foundations, and many homeowners in the state face foundation problems. Here are some of the most common foundation issues in North Carolina.
SETTLEMENT
Settlement occurs when the soil beneath a foundation compresses, causing the foundation to sink. This problem can be caused by various factors, including soil erosion, changes in the moisture content of the soil, and poor soil quality. Settlement can result in cracks in the foundation walls or floors, uneven floors, and doors and windows that do not close properly.
EXPANSIVE SOIL
Expansive soil is soil that expands and contracts with changes in moisture content. This soil can put pressure on the foundation, causing it to shift and crack. Expansive soil is common in North Carolina’s Piedmont region, where clay soils are prevalent. Signs of expansive soil problems include cracks in the foundation walls or floors, windows and doors that do not close properly, and uneven floors.
POOR DRAINAGE
In areas with heavy rainfall or poor drainage, water can collect around the foundation and cause the soil to shift, leading to foundation damage. Over time, this can cause the foundation to shift and crack. Signs of poor drainage include standing water around the foundation, water seeping into the basement, and mold growth.
POOR CONSTRUCTION PRACTICES
Foundation issues can also be caused by poor construction practices, such as using insufficient or inadequate materials, improper reinforcement, or improper grading. Signs of poor construction include cracks in the foundation walls or floors, uneven floors, and doors and windows that do not close properly.
OTHER ISSUES
- Natural disasters such as earthquakes, hurricanes, and tornadoes can cause wall cracks by putting pressure on the walls and causing them to shift or buckle.
- Trees planted too close to the foundation can cause foundation damage by absorbing moisture from the soil and causing it to shift.
- North Carolina’s humid climate can cause moisture problems in homes. Water can seep through the foundation walls, causing dampness and mold growth. Excess moisture can also cause wood rot and termite infestations. Poor drainage around the foundation can exacerbate moisture problems.
- Sinkholes can form in areas with karst topography, which is common in parts of North Carolina. Sinkholes can cause foundation damage by creating voids in the soil that can cause the foundation to settle or shift.
Foundation problems are common in North Carolina, and homeowners need to be aware of the signs of foundation issues. Settlement, expansive soil, poor drainage, and poor construction are all common issues that can cause foundation problems. It’s important to note that foundation issues can lead to serious structural problems and safety hazards if left untreated. If you suspect that your foundation has been damaged, it’s essential to consult a licensed foundation repair contractor who can assess the extent of the damage and provide the necessary repairs.
