Brick wall crack repair methods

    Repairing of Cracks in Brick Wall (Crack width below 2 mm):

  • If the cracks remain under 2 mm in width, then the crack can be repaired with the snowfilla paint (ACC make) that is extended in the cracks after it becomes dry. It is recommended to cure painted crack for minimum five days.
  • Repairing of Cracks in Brickwork (Crack width among 2 mm to 5 mm):

  • If the cracks remain among 2 mm to 5 mm in width, then the crack should be repaired by injecting the flowing grout in the ratio like cement 1 kg, grout polymer 0.1 kg, and 1-litre water. Bore the hole at a distance of 350 mm c/c for attaching the nipple with the sealant. The grout mixture is injected with the pressure of 3 kg/cm2 through a pressure pump.
  • Repairing The Cracks In Brickwork (Crack width among 5 mm To 10 mm):

  • If the cracks remain among 5 mm to 10 mm in width, then eliminate all the loose materials and keep the width of the groove of cracks as 25 mm and depth as 10 mm. Detach the plaster up to a width of 300 mm on the both sides of the cracks and fill the groove with CM 1:3 having 10% polymer by weight of cement. Once the cracks are filled, 12 mm diameter nipples should be inserted at 100 mm c/c and 30 mm to 40 mm deep along the crack line and employ the above grouting method for grouting the cracks.
  • Repairing of Cracks in Brick Masonry (Crack width over 10 mm):

  • Eliminate all the loose materials from the crack and detach the plaster up to 450 mm on both side of the cracks. Fill the cracks with CM 1:3 with 10% polymer by weight of cement.
