Common Causes of Concrete Cracks
Shrinkage
Concrete shrinks slightly as it cures. Fine surface cracks from this process are common and rarely structural.
Settlement
When the base under the slab moves or compacts, cracks form as the slab follows.
Freeze/Thaw
Water in cracks expands as it freezes, widening damage over Illinois winters.
Overload
Weight beyond what the slab was designed for can crack it.
Poor Jointing
Missing or badly placed control joints cause uncontrolled cracks.
When to Take a Crack Seriously
- The crack is wider than a credit card
- One side is higher than the other
- The crack is growing over time
- Water is pooling near or in the crack
- The slab is moving under load
Options for Cracked Concrete
- Seal and monitor non-structural cracks
- Cut out and patch localized damage
- Replace the section or full slab when damage is widespread
Frequently Asked Questions
Are all concrete cracks a problem?+
No. Hairline shrinkage cracks are common and often cosmetic. Wider, moving, or offset cracks usually point to a structural cause.
Can a crack be repaired without replacing the slab?+
Sometimes. Localized cracks in an otherwise sound slab can be sealed or patched. Widespread or moving cracks often require replacement.
