Q:Roof waterproof mattress should play the number of centimeters appropriate
  3. The first layer to do flexible waterproof, that is, roof-specific anti-aging waterproof coating.
Q:Why calculate the amount of time to count a lot of cushion ah
In the building construction refers to the base is located below the cushion sometimes also served as grassroots. With the cushion, in the above work is convenient, clean, especially the mold, bar reinforced, pouring concrete and other processes, will not be affected by the basic earth pollution. Set the place where the cushion is generally based, floor, roof (slope) and so on.
Q:What is the difference between leveling and cushion?
and only in the construction of the building at the bottom of the building, it is possible to use the relevant level of the cube, After the use of the underlying layer of the building, it is not exempt from the possibility of using leveling layer
Q:Is foam concrete suitable for use as a cushion?
Inappropriate. Bubble concrete is a new type of energy-saving and environmentally friendly building materials, which are widely used in wall materials, but there are still some defects, such as low strength, cracking, water absorption, as the cushion of its strength is not enough standard.
Q:Maintenance time of the cushion on the roof of the building
Concrete watering maintenance time: the use of Portland cement, ordinary Portland cement or slag Portland cement mixed with concrete, not less than 7d;
Q:Is it possible to make a waterproof layer
1, to do after the dry do, or prone to the phenomenon of wall skin off.
Q:How to build a fine stone concrete cushion?
Reduce ground cracking, plus steel mesh. Reinforced mesh, should be placed in the middle of the concrete, because the protective layer of concrete thick Fang generally only 5CM thickness, so the middle is the best.
Q:Foam concrete for the roof cushion generally do much bulk ah
First help you correct it, foam concrete used in the roof should be the role of thermal insulation, not as a cushion.
Q:Why do the basics of the cushion waterproofing
As for the bottom of the bar thickness of the protective layer is generally 4cm, but if the basic floor of the concrete label is relatively high, the protective layer can be appropriately reduced.
Q:What is the relationship between the cushion and the ring beam?
Ring beam is reinforced concrete. Is to increase the overall wall and overall stiffness, improve the side resistance performance, according to the earthquake or masonry specifications set. There may be in the ground wall, there may be in the underground wall.
