Identifying and Repairing a Cracked House Foundation
Finding cracks in your home's foundation can be unsettling, but not all foundation cracks are a cause for concern. However, it's essential to know when a crack requires immediate attention and when it can be left to a professional to evaluate and repair. In this article, we'll explore the causes of foundation cracks, how to identify them, and the DIY and professional steps for repairing a cracked house foundation.
Causes of Foundation Cracks
Foundation cracks can occur due to various reasons, including:
- Settling of the foundation over time
- Soil movement and water absorption
- Shrinkage and expansion of the concrete
- Poor construction or foundation installation
- Age and deterioration of the foundation
Identifying Foundation Cracks
Not every crack requires immediate attention. However, certain signs suggest that foundation cracks are serious enough to warrant professional evaluation. These include:
- Large cracks wider than 5 millimeters. These can indicate foundation movement, stress on structural supports, or settling issues.
- Diagonal or horizontal cracks. These can indicate structural problems or settling issues.
- Cracks above door frames or near corners. These can indicate stress on structural supports or settling issues.
DIY Repair Options for Small Cracks
For small, hairline cracks, you can try a DIY repair using:
- Urethane caulk
- Concrete patching compound
- Epoxies or polyurethane-based sealants
Apply the chosen sealant to the crack, following the manufacturer's instructions. However, for larger or more extensive cracks, it's recommended to seek the help of a professional foundation repair specialist.
