However, it is necessary to reverse the bottom beam of plain concrete. Aerated bricks, sintered gangue bricks or autoclaved lime-sand bricks can be laid on it. Except for rooms with plenty of water, ordinary concrete small hollow blocks use skirting lines (slabs) to cover possible shrinkage cracks at the bottom of infilled walls, mainly to improve the waterproof effect of the bottom of infilled walls in rooms with plenty of water.

Extended data:

The details shall be constructed first, and the grooves, holes and wall-penetrating pipes of each drainage pipe shall be closed. Scour the ground, clean up the accumulated water in time, and the washed water shall not flow out of the construction scope to prevent leakage from damaging the downstairs. Make sure there are no floating dust, sand and debris. After cleaning the walls and floors, flush the pipes with water to prevent the pipes from being blocked.

In large-scale construction, the wall shall be constructed first, and then the ground shall be constructed, and there shall be no construction omissions. For the treatment along the entrance, the water stop along the entrance should be added according to the existing materials on site. If the height meets the test conditions (there is water on the toilet floor), it is best not to affect the laying of the entrance stone.

The construction is completed. Finally, check whether there are any defects in the waterproof layer construction as a whole to ensure that there are no omissions in the construction process. Pack up the cleaning tools. In principle, cleaning water should not be spilled in the room to prevent it from leaking to the downstairs room. Before leaving the site, if there are no other construction workers, the water diversion valve, main water valve, main power switch and doors and windows must be closed.
