Walls

Cracks along the joints between/ in the block wall and reinforced concrete elements.

• Why it happens:
  • Different materials expand and contract with temperature changes. Over time, this differential movement will result in cracks along the joints
• Solutions:
  • For hairline cracks: re-paint the wall with a flexible sealant/ elastomeric paint to seal the cracks
  • For wider cracks: engage a contractor to carry out the repair works
• Preventive measures:
  • Facilitate cross-ventilation in the flat
  • Re-paint the walls regularly
