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: The cushion is usually in the housing which parts: There was no other place in the house below

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: 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: Can the floor tiles be removed from the cement mats on the prefabricated board floor?: Cement cushion as a leveling layer on the floor, not designed to the structure of the load-bearing, the general can be dug, the cushion is generally 3 to 5 cm, chisel in addition to unloading the floor of the heavy objects, chisel in addition to the use of strong vibration Machine or penetrating machine is too large, with a small hammer small chisel, along the horizontal plane horizontal chisel, stripping cement cushion.

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: 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 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: Basement floor mattress dry to what degree can do coil waterproof?: First, the basement moisture treatment structure is usually: first in the basement wall outer surface wiping 20mm thick 1: 2 waterproof mortar, basement walls should be used cement mortar masonry, gray seam must be full; and in the basement floor and the first Floor floor is divided into two walls of the level of moisture-proof layer. The outer wall of the basement wall should be tampered with the soil with poor permeability.

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;
