Walls

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

wall cracks

  • 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
