The concrete poured in site can be filled with continuous joint or cold joint, which is easy to produce honeycomb or filling the bad part, forming the congenital shrinkage crack. Especially large span walls or protruding outward from the wall structure for this situation is more common podium.

3, around the mouth

Not only confined to the concrete structure, around the opening is waterproof, easy to form weaknesses in the construction site. In the pouring of concrete tiles or by template method with pre occasions, as long as the attention window can be, but in the painted decoration or tiles affixed to the top of the window around the place, there will be floating debris, like cement or concrete, void for horizontal or reverse slope situation, will form a site full of flaws.
