Your home’s foundation is one of the most important aspects of your property. Unfortunately, it’s also often one of the most vulnerable. Today, we’ll take a look at common causes of foundation cracks, when to be concerned, and when there’s likely no cause for alarm.
Types Of Foundation Cracks
First, it’s important to know that all homes settle a bit in the first few years. These are usually barely noticeable vertical cracks that happen as the concrete cures and adjusts to its environment. They are typically even and remain the same size. Other cracks, however, aren’t as benign. These include:
- Soil expansion and contraction cracks. As the surrounding soil retains and expends moisture, it can cause the foundation around your home to expand and shrink. This type of movement can lead to cracks, especially in areas of heavy clay soil.
- Hydrostatic pressure. Hydrostatic pressure cracks happen when your foundation is subject to heaviness in the soil caused by excessive water buildup. This can be triggered by poor drainage, heavy rains, or rapidly melting snow. Horizontal cracking and bowing should be monitored for changes.
- Frost cracks. During particularly bad winters, the ground can take on a deep freeze. This causes soil to expand upwards, which can lift the foundation, leaving it damaged.
In addition to the above, your home may also be subject to poor soil compaction, tree roots, and even seismic activity, although the latter is not common throughout the southern United States.
When To Worry
Within each type of crack there will be varying levels of potential damage. A general rule of thumb is that cracks wider than the thickness of a nickel should be inspected by a professional. Further, horizontal cracks warrant immediate attention, as they often indicate bowing walls and potential structural damage. If you notice water leakage, bulging or bowing walls, or suddenly sticking windows and doors, you might have a problem.
