Understanding the problem
Foundation cracks vary widely. Some are associated with normal concrete shrinkage, while others may signal water intrusion, soil movement, settlement, or lateral pressure. A contractor can assess waterproofing-related cracks; movement, bowing, or major structural concerns may require a licensed engineer.
Common professional options
The appropriate approach must be based on an inspection. A professional may discuss:
- Crack injection or sealing
- Exterior excavation and membrane work
- Wall reinforcement
- Engineer referral when appropriate
