Q: Can the cushion on the prefabricated board floor be dug?: Prefabricated board floor layer of cement layer is not called the cushion, should be called leveling layer, this layer can be removed, but be careful not to damage the prefabricated plate.

Q: Foam concrete for the roof cushion generally do much bulk ah: Foam concrete density grade is generally 300-1800kg / m3, commonly used foam concrete density grade 300-1200 kg / m3,

Q: The roof cushion is waterproof on the slope roof: Most of the slope roof itself is not waterproof. The role of the slope roof is used for drainage,

Q: Is the raft cushion waterproofing full of the cushion?: 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: 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: 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?: In the tile roof, to wait for the waterproof layer after the dry layer, or prone to the phenomenon of wall off. 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 Hour) 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: How to build a fine stone concrete cushion?: The main role of the cushion is to meet the requirements of the design elevation. In addition, the cushion to meet the sound insulation, insulation, insulation, slope and buried pipeline and other functional requirements and set a variety of levels.

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: 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;
