The state of Tennessee is located in the Southeastern region of the United States. The state is divided into three geographical regions: the rugged terrain and Blue Ridge area of East Tennessee, the elevated plain and Nashville basin of Middle Tennessee, and the Gulf Coastal plain of West Tennessee. The climate throughout the state is predominantly humid subtropical, with hot, humid summers, and mild to cool winters, although the higher regions have colder winters and more of a mountain temperate or humid continental climate. These hot conditions and the occasional remnants of tropical storms in the state can spell trouble for your foundation.
There are many different factors that can effect your foundation. Some of the most common of these factors that cause foundation problems in Tennessee are:
Erosion: When a severe rain follows a long dry spell, erosion can occur, washing away the soil under your home and creating voids. These voids cannot support the structure, and the foundation will settle into them as a result.
Soil Shrinkage: This occurs when dry, drought-like conditions cause the soil to shrink form lack of moisture. Soil shrinkage, like erosion, can form voids that lead to foundation settlement.
Vegetation: If there are trees or large shrubs planted close to your foundation, the roots may push against the foundation in their search for moisture, putting stress on it and causing shifting and cracking.
Poor Soil Compaction: If the soil under your home is not properly packed when the foundation is poured, it will settle over time, causing the home above to settle and sink unevenly as well.
Shifting, settling, sinking, or crack formation are common foundation problems that often lead to other issues in the home. If you see water problems or pest infestation, or structural instability in your home, it may be a sign that your foundation is failing. Examine your foundation for issues to catch foundation problems as soon as they occur. Some common signs of foundation problems to look for in your home include:
Sloped or uneven floors
Sticking doors or windows
Bowed or leaning walls
Settling and sinking foundations is one of the most common foundation problems in Tennessee. Fortunately, there is a solution; the installation of helical piers or steel push piers. These piers are installed into the load bearing soils deep underground to support the weight of the structure while lifting and stabilizing the foundation. Steel piers and helical piers work much the same way, except steel piers are driven into the ground, while helical piers are screwed into the ground. This solution can also help to close cracks that may have formed as a result of the settlement.
If you have a shifting foundation, one viable solution is to install helical tiebacks. These are large, screw-like devices that pull the foundation back into position by applying opposite lateral pressure.
