Q: Do you need a cushion on the ground floor?: In addition to wood also buy wooden side, used as the main beam, beam and pillars. The ground is also recommended to raise, raise the place also to beam and pillars The number of boards to be based on your design to determine the ground practice, roof practices will affect the number of wood

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

Q: Foam concrete for the roof cushion generally do much bulk ah: in recent years, the density of 160kg / m3 ultra-light foam concrete is also used in construction projects.

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: Can the floor tiles be removed from the cement mats on the prefabricated board floor?: Prefabricated board surface is best to do some cement mortar cushion, can prevent the decoration of the water generated to the downstairs.

Q: Large area ground concrete cushion seam Why is the separation of joints generally concrete: Second, sub-grid seam set In order to reduce the total shrinkage and temperature stress of the large area waterproof layer, avoid the leakage of the waterproof layer due to the deformation of the structural layer and the change of the temperature and humidity, the waterproof layer should be divided according to the shape, size and structure of the flat roof, Stay sewn. The waterproof layer is divided into several squares.

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: Why calculate the amount of time to count a lot of cushion ah: ? In the municipal engineering, the bedding layer is a structural layer between the grassroots and the soil foundation. When the soil temperature is bad, the water temperature of the soil is improved and the water stability and frost resistance of the pavement structure are improved. Diffusible load to reduce soil deformation.

Q: Maintenance time of the cushion on the roof of the building: for the incorporation of retarding admixture or impermeable concrete , Not less than 14d;
