Repairing of cracks has to be attended by ensuring that the settlement causing the crack has ceased. This generally takes about one year for the complete settlement.
Small cracks are cleaned with a wire brush and a thick paste of cement mix is forced into the crack. In order to get a firm key for the mortar, large cracks should be raked. An inverted V groove is made with a minimum of 1 cm depth. A cement mortar of 1 : 2 ratio is applied with less water. The mixture is forced into the crack to get a firm bond. Along with this mixture expansive agents are added to improve the bond.
