Introduction: How Foundation Cracks Occur
Foundation cracks can be a serious problem for homeowners. They can lead to water damage and structural damage to your home. In this article, you get more information about different types of foundation cracks and how you can prevent them from happening.
Foundation cracks happen when the soil beneath your home shifts or shifts too much. This can happen due to a number of things, including rain, frost, or even earthquakes. When the soil shifts, it causes the foundation to crack.
There are a few different types of foundation cracks. The most common type is called an expansion crack. Expansion cracks are caused by excessive moisture in the soil. They typically form in areas where the soil has been wet for a long time or in areas where there is a lot of pressure from above like on top of an underground storage tank.
An excavation crack is slightly different from an expansion crack. Excavation cracks are usually caused by something heavy being dropped on the ground below your home like a water tower. They usually form at the base of your home where the ground has been disturbed.
Another type of foundation crack is called a shear failure crack. Shear failure cracks are usually caused by wind or seismic forces.
