Use 1:2 cement mortar to build the wall. The bricks or lightweight bricks should be staggered, the wall should be vertical, the vertical deviation should be less than 20mm, the mortar should be full, the blocks should be watered and moist, and the surface should be smooth.
Concrete beams should be poured on the doors and windows, which can reduce the stress on the doors and windows and prevent deformation. There should be threaded steel mesh inside the construction piles and columns. If the top of the building is flat, attention should be paid to preventing water leakage.
