Foundation cracks can be a common occurrence in homes, but not all cracks are created equal. Some may be harmless, while others could indicate serious structural issues. Understanding the difference is crucial for the safety and longevity of your home. Here’s a guide to help you determine whether your foundation crack is serious and what steps to take.
Different Types of Foundation Cracks
Hairline Cracks-Typically very thin cracks in the foundation walls, often less than 1/8 inch wide.
What causes them-Usually due to the natural settling of the house or minor shrinkage in the concrete as it cures.
Severity of the crack-Generally considered non-structural and not a cause for concern unless they expand and get bigger over time.
Vertical Cracks-Are Cracks running up and down the foundation walls.
What causes them-Often caused by the natural settling of the home and minor concrete shrinkage.
Severity of the crack-Usually non-structural but should be monitored for changes in size.
Diagonal Cracks-Foundation Cracks running at an angle.
What causes them- Often due to differential settling, where one part of the foundation settles more than another.
Severity of the crack-Can be a concern if they are wider at one end, indicating uneven settling which could lead to structural issues.
Horizontal Cracks–Foundation Cracks running horizontally across the foundation.
What causes them-Usually caused by soil pressure against the foundation wall.
Severity of the crack- Often serious and indicative of significant structural stress. Horizontal cracks can lead to foundation wall failure if not addressed promptly.
Stair-Step Cracks-Cracks that follow the mortar joints in a stair-step pattern on the foundation block wall.
What causes them-Common in brick or block foundations, usually due to differential settling.
Severity of the crack-Can range from minor to serious depending on the width and movement. Larger cracks could indicate structural issues.
Signs Your homes Foundation Crack May Be Serious
Width and Expansion-Cracks wider than 1/4 inch, or those that continue to widen over time, are a red flag.
Displacement-If one side of the crack is higher or lower than the other, it suggests significant movement and potential structural problems.
Moisture– Water seepage through cracks can erode the foundation and lead to mold and mildew, indicating the need for immediate repair.
Location-Cracks in the corners of your foundation or running horizontally are more likely to be serious.
Frequency- Multiple cracks appearing simultaneously or new cracks forming quickly can indicate a more extensive problem.
What To Do If You Suspect a Serious Crack in your foundation
Monitor the Crack-Use a pencil or marker to trace the crack and note the date. Check it regularly to see if it’s expanding.
Hire a Professional Foundation repair company-Engage a structural engineer or a foundation specialist to assess the crack. They can determine the cause and suggest the best solution for you and your home.
Get a Soil Report-In areas with expansive clay soils, soil movement can be a significant issue. A soil report can provide insight into whether soil conditions are contributing to foundation problems.
Consider Basement Waterproofing-If moisture is an issue, waterproofing your basement can prevent water from exacerbating the problem.
Foundation Repair-Depending on the severity, repairs might include epoxy injections for small cracks, installing piers for significant settling, or full foundation wall rebuild.
Prevention Tips for cracks in foundation
