We are still talking about the reinforcing steel work for the first floor ceiling, upon completion of the main and footbridges, the contractor must emphasize the need to raise the reinforcing steel from the ceiling well by using cement pieces that are prepared on site or by placing tiles, after that the ceiling is cleaned and the horde is supplied and placed directly on the ceiling.

If the horde used for the ceiling is polystyrene (cork) and when there are protrusions on the front of the ceiling, it is necessary to put it on the ceiling.

If the horde used for the roof is polystyrene (cork) and there are protrusions in the front of the building or any other parts of the roof to be lined, it is necessary to use in these parts cement horde blocks or red bricks in order to hold the lining on it well, as the lining cannot be carried out on cork horde.

If the roof is polystyrene (cork) and there are protrusions in the front of the building or other parts of the roof where the lining will be made

When the horde is completed, the reinforcing steel for the nerves that connect the main bridges to each other is started, then the reinforcing steel is spread on top of the horde and covers it according to the approved plan for the project.

After that, the blacksmith makes the inverted bridges under the roof jacket, the height of the inverted bridge should not be less than 30 cm and preferably 40 cm, the inverted bridge limits the future creep of tiles in surfaces exposed to weathering, we usually see cracks under the roof jacket in existing buildings due to the absence of inverted bridges, no inverted bridges are made under the walls of the roof accessories. Upon completion of all rebar work on the roof, plumbing and electrical materials are secured in preparation for the start of the "plumbing, electrical, and air conditioning" works, and we inform the kind reader that our reference in this series is the book Stages of Building Residential Villas (Part I) Structural Structure Stage "Bone".

Which is better for installing porcelain flooring, cement mix or glue?

If the tiles to be installed for the floors are porcelain, it is recommended that after preparing the site and placing the burial, a cement mix is made for the floors (cement + white sand): Cement + white sand) and this mixture is spread on the tambourine with a thickness of 3 to 5 cm and its surface is completely flat and rough, the cement mixture is sprayed with water for four days, after that the floors are cleaned and start installing the tiles using adhesive glue intended for this purpose, and make sure to acquire high-quality types of glue, the glue is used to install porcelain to ensure that the tiles do not come loose, it is good to acquire tiles with grooved surfaces from the back to ensure the strength of the adhesion of the glue to the tiles.
