Types of Cracks
1. *Hairline cracks*: Small, shallow cracks (usually 1 mm wide)
2. *Structural cracks*: Deeper, wider cracks that can compromise the structure's integrity
3. *Thermal cracks*: Caused by temperature changes, expansion, and contraction
4. *Shrinkage cracks*: Occur due to drying shrinkage of concrete
5. *Settlement cracks*: Result from settlement or movement of the foundation

Repair Process
1. *Assessment*: Evaluate the crack's cause, size, and impact on the structure
2. *Cleaning*: Clean the crack area to ensure proper bonding
3. *Sealing*: Apply sealants or fillers to the crack
4. *Reinforcement*: Install reinforcement materials (e.g., rebars, mesh) if necessary
5. *Finishing*: Apply a finish coat to match the surrounding surface
