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.

Q:Maintenance time of the cushion on the roof of the building: According to the "concrete structure construction quality acceptance criteria" provides: Concrete should be poured within 12h after the completion of the concrete to be covered, and moisturizing conservation;

Q:What is the difference between leveling and cushion?: Cushion is generally used in the ground floor of the building, leveling layer is generally used in the floor or roof. According to the above analysis, I believe that we use the quota, where the floor, roof construction, it should be used to find the level of the fixed sub-head, because there is no so-called concept of the cushion, leveling layer thickness is not what Specific provisions can also be used at the same time different layers of leveling, but must be carried out in accordance with the design requirements, so as not to exceed the load;

Q:The top floor made waterproof playing cushion layer of how to do: 2. repair the cracks well. After the cracks to be repaired are dry, start waterproofing.

Q:Is the raft cushion waterproofing full of the cushion?: 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:Basement floor mattress dry to what degree can do coil waterproof?: Third, the membrane waterproof in the construction should first do the basement floor of the waterproof, and then the membrane along the basement floor continuous paste to the outer surface of the wall. Basement floor waterproofing first in the foundation pouring C10 concrete cushion, the thickness of about 100mm. And then paste the membrane, and then in the coil to wear 20 thick 1: 3 cement mortar, and finally pouring reinforced concrete floor. The outer surface of the wall first wip 20mm thick 1: 3 cement mortar, cold base oil, and then paste the membrane, the membrane should be stitched paste, adjacent coil lap width of not less than 100mm. The top of the coil should be higher than the maximum water level of about 500mm, the outer side of the brick wall.

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:Basement cushion waterproof: Fourth, improve the waterproof performance: 1, Aggregate graded concrete, is the use of different aggregates of the aggregate and improve the content of cement mortar in the concrete, so that the mortar is filled between the aggregate, thus blocking the aggregate is not dense between the seepage channel , Improve water resistance; 2, plus concrete, is added in the concrete air conditioner or dense agent to improve the impermeability.

Q:Cushion, waterproof layer construction to do what information: 4, waterproof layer set and standard construction methods: to be painted 2 to 3 times, or should be added fiberglass cloth, and each brushing the thickness of the cured material shall not be less than 1 mm, and should be completely dry (about 5 -8 hours) and then the next construction. After brushing, but also in the paint waterproof layer to do a mortar protective layer, and finally paste the tile.

Q:Is it possible to make a waterproof layer: 3, waterproof layer set and standard construction methods: to be painted 2 to 3 times, or should be added fiberglass cloth, and each brushing the thickness of the cured material shall not be less than 1 mm, and should be completely dry (about 5 -8 hours) and then the next construction. After brushing, but also in the paint waterproof layer to do a mortar protective layer, and finally paste the tile.
