Crazing Cracks in Concrete: Should I Worry?

Crazing cracks are fine spiderweb cracks that are purely cosmetic. They're caused by surface drying too fast. Seal concrete to hide them. Understanding crazing helps you know it's not a structural concern.

Crazing is:

• Fine spiderweb cracks: Very fine, interconnected cracks
• Surface only: Only affects surface layer
• Cosmetic: Purely cosmetic, not structural
• Harmless: Doesn't affect concrete strength

Crazing is caused by:

• Surface drying too fast: Surface dries faster than interior
• Shrinkage: Surface shrinks while interior doesn't
• Temperature/humidity: Hot, dry conditions increase risk
• Improper curing: Not properly protecting surface

Should You Worry?

No—crazing is:

• Cosmetic only: Appearance issue only
• Common: Very common, happens often
• Harmless: No need to worry
