Brick arches are a kind of arched masonry, which looks most effective in the width of the opening of 2 m or more. Initially, for the formation of a brick arch along its contour, it was made circled, it makes up the formwork on which bricks are laid, and after the solution hardens, the formwork is eliminated from the doorway. For the formation of brick arches, pattern bricks are most often used, since one end of it is wider than the other, which allows you to create the same seams between bricks. When using conventional brick, the seams of the binder solution will have a cone -shaped look, while their width should not exceed 25 mm in the upper part and be less than 5 mm in the lower.
