The Vertical seam (backlash) dividing walls of a building on all height, name deformation. Its appointment - to prevent occurrence of cracks in walls and other designs from non-uniform deposits of a building or difference of temperatures.

Sedimentary seams divide a building on length into parts to warn destruction of designs in case of possible non-uniform deposits of separate parts. Sedimentary seams pass from building eaves dopodoshvy the base, an arrangement of seams specify in the project.

Seams in walls (fig. 65, and, carry out in a kind shpunta in the thickness, as a rule, 1 / 2 . A brick or in a quarter with a lining in a backlash of a laying of a package from the tarred tow which has been wrapped up by two layers of roofing felt, and in the bases (fig. 65, - without shpunta. Over the top sawn-off shotgun of the base under shpuntom walls leave a backlash (pocket) on laying height in 1... 2 bricks that at a deposit shpunt did not rest against a base laying. Otherwise in this place the laying can collapse. Sedimentary seams in the bases and walls zakonopachivajut the tarred tow.

Deformation seams: and - at interface of walls in shpunt, - the same, in a quarter; in - transition from a sedimentary seam of the base to a sedimentary seam of a wall; the A-A-cut, the wall B-B-plan, the base V-V-plan; 1 - a wall, 2 - a lining, 3, 5 - a wall seam, 4 - shpunt, 6 (above) - a backlash (a pocket) for deposits, 6 - a base seam

And - at interface of walls in shpunt, - the same, in a quarter; in - transition from a sedimentary seam of the base to a sedimentary seam of a wall;
A-A-cut, the wall B-B-plan, the base V-V-plan;
1 - a wall, 2 - a lining, 3, 5 - a wall seam, 4 - shpunt, 6 (above) - a backlash (pocket) for deposits, 6 - a base seam

That superficial ground waters have not got into a cellar through a sedimentary seam, from lateral aspect it arrange the clay lock or apply other measures provided by the project.
