If the crack is through and has an opening of more than 4 mm in the wall, the thickness of which consists of half of the brick, then it can only be eliminated by disassembling the masonry.

Dismantling must start from both sides to a depth of half the brick, in turn from each side. The masonry that remains is required to rinse well with cement milk, and then lay out a diverse area, using full -shaped brick, whose brand is 100 on a cement solution.
When reconstructing a brick building or with its emergency condition, it may be necessary to carry out a complete disassembly of the masonry. In such cases, for a start, it is required to install between the jumpers and sections of the window sills for the time of the rack, from such a material as wood or metal. If the width of the wall is more than one meter, then you need to install two or more racks. For new masonry, it is not recommended to use a brick that has a brand at least 100. The seams that are located horizontally reinforce, should not be thin.
