A cracked foundation can lead to significant issues if not properly dealt with, including home structural damage. Some types of foundation cracks are more concerning than others and may require the assistance of a professional.
Types of Foundation Cracks
1. Horizontal
Horizontal foundation cracks run side to side and are a sign of bigger issues that need attention. Soil and outside water pressure against the concrete can cause cracks to form in the wall, which can eventually lead to the foundation failing and the home collapsing.
Horizontal cracks are a big deal and should be inspected and repaired by a professional as soon as possible.
2. Vertical
Vertical cracks in the foundation wall run up and down and are typically not as serious as horizontal cracks. This type of crack is often caused by the foundation settling and the concrete shrinking as it cures. Vertical foundation cracks are common in new construction and are typically located in the middle of the wall.
If you find vertical cracks that are wider than 1/8th of an inch or are located near a corner, there may be bigger issues causing the cracks, and you should consult a professional.
3. Hairline
Are hairline cracks in the foundation normal? Yes. As concrete shrinks, thin hairline cracks in concrete or cinder block foundations can form. In cinder blocks, hairline cracks can occur in the mortar rather than running through the cinder block.
They’re not usually a cause for concern as long as they’re 1/8th inch wide or smaller. It is important to monitor these cracks to ensure they are not getting bigger, and are not leaking water.
4. Diagonal
Diagonal cracks in the foundation are usually caused by the foundation settling. Like vertical cracks, diagonal foundation cracks are common in new construction and are typically located in the middle of the foundation wall.
If the crack is wider than 1/8th of an inch, there may be a bigger issue and you should have a professional inspect the foundation crack.
5. Structural
Changing temperatures, water pressure, soil pressure, and soil shrinkage can all cause the concrete to move, leading to structural cracks in the foundation. These foundation cracks are typically 1/4th of an inch or wider and can negatively affect the structural integrity of your home.
A structural crack in the house foundation should be inspected and repaired by a professional as soon as possible.
