- Q: Can the cushion on the prefabricated board floor be dug?
- 1, can not be dug, the prefabricated board seam is too big. 2, in addition, now rarely used prefabricated panels, the earthquake effect is not good; especially after the Wenchuan earthquake. If it is cast-in-place floor, you can dig out.
- Q: Do you need a cushion for roof waterproofing?
- There is no "cushion" on the roof, and there is a concrete cushion under the basement floor. What you said may be leveling, is the base of the waterproof layer.
- Q: When the cushion is used, the thickness of the protective layer is not less than ()
- Master roof: the general use of 40 thick C20 reinforced fine stone concrete protection.
- Q: Why do the basics of the cushion waterproofing
- The general basis of the foundation, the bar base is not necessary to do, like a raft in the basement, it is necessary to prevent the water from dipping into the basement (so the basement design may have to do anti-floating calculations). Assuming (just suppose) the raft can easily turn over, then we do waterproof (like roof) directly on it, not waterproof on the cushion.
- Q: The roof cushion is waterproof on the slope roof
- and the formation of the ice dam will lead to roof water, water will find the path into the house.
- 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: Large area ground concrete cushion seam Why is the separation of joints generally concrete
- Large area of ??concrete after concrete construction, the concrete volume will be slightly inflated, the ground for a long time deposition, will be sinking, all large area of ??concrete construction, the general set of separation joints.
- Q: What is the waterproof layer and the waterproof cushion in the tile roof?
- Waterproof layer: set in the tile or metal sheet below, from the waterproof, moisture-proof structure of the layer. The waterproof cushion plays an important role in the tile surface, because the "tile" itself can not be counted as a waterproof material, only tile and waterproof cushion combination to form a waterproof fortification.
- 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: Basement floor mattress dry to what degree can do coil waterproof?
- Second, when the design of the highest groundwater level above the bottom of the basement floor, you must do waterproofing. As the waterproof waterproof effect is good, so the application of more. Internal waterproofing is generally used for repair works.
