Before to close up cracks, it is necessary to eliminate the reasons causing them, and then to be convinced that deformations of walls have ended, and cracks do not increase. For this purpose across a crack in several places impose beacons (fig. 152, from a plaster solution in width 50... 100, thickness 6... 10мм. If walls are plastered, in installation sites of beacons plaster force down, clear away laying seams, clear a laying and its seams of a dust and wash out water. It is impossible to put beacons on the crude and not washed out laying as they will not be linked to it and the crack increase in a laying will not be reflected in a plaster beacon. On beacons write date of their installation. If, for example, in two-three weeks after installation on beacons there will be no crack, it means that wall deformation has stopped. Term of the control of deformations on beacons appoint depending on the prospective reasons of deformations. Thin cracks clear of a dirt and a dust and fill with a liquid cement mortal, forcing it inside rastvoronasosom. Wide cracks close up, assorting parts of an old laying and replacing its new.
At zadelke cracks in walls in the thickness 1 1 / 2 a brick a laying assort and close up consistently separate sites for all thickness of a wall in the form of brick locks. If a thickness of cracks considerable for a laying fastening often put anchors or beams (metal communications) (fig. 152, ). These beams close up in a laying the same as over punched apertures arrange crosspieces.
At zadelke thin rents in the wall in the thickness 2 bricks and more at first break a laying along a crack into depth 1 / 2 a brick (fig. 152,) from each party of a wall. After that a crack wash out water, establish a timbering and force in it a liquid cement mortal of structure 1:3 or 1:2 sites in height 1... 1,5м. Then the disassembled laying put from both parties of a crack a brick vperevjazku with an old laying.

Repair of piers . At repair of piers adjacent apertures put a bricklaying on a clay solution or establish in them the time racks perceiving loading from an overlying laying. Then consistently assort and replace the destroyed laying new and after it gets necessary durability, assort a time laying or remove time fastenings.
