There are many causes which develops cracks in the building. Main causes of cracks in the buildings are following.
• drying and shrinkage
• thermal movement
• elastic deformation
• due creep
• chemical reaction
• foundation movement and settlement in soil
• growth of vegetation
Cracks in wall generally develop due to following factors.
• Settlement in foundation
• Weak mortar
• Weakening of mortar due to sulphate effect.
• Slip joint not proper between wall and RCC slab
• Improper bonding of cross wall with main wall
• Differential movement between RCC and masonry
• Deflection of beam under wall
• Deflection of slab
