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:Can the cushion on the prefabricated board floor be dug?
Surface layer without steel, do not bear the load, you can dig out But sometimes the prefabricated floor above the surface layer with steel, to bear the load, this can not be removed! To know how thick the cushion, in the local dig about In general, to do leveling layer, can not be directly laid tiles
Q:Roof waterproof mattress should play the number of centimeters appropriate
  3. The first layer to do flexible waterproof, that is, roof-specific anti-aging waterproof coating.
Q:Why do the basics of the cushion waterproofing
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: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 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: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:The top floor made waterproof playing cushion layer of how to do
Roof waterproofing can not use a single waterproof material, must be rigid and flexible combination of construction, flexible waterproof stretch is good, a little bit of settlement or deformation will not damage the waterproof layer. Rigid waterproof (ie mortar waterproofing agent) waterproof at the same time, can play a protective role, waterproof layer is not easy to be destroyed.
Q:What is the difference between leveling and cushion?
Building floor cushion is the structure layer below the grass-roots level. Cushion as the name suggests is the structure of the liner layer, mainly plays the role of the back cover. Cushion should be noted with the basic distinction. It is easy to confuse the two engineering concepts.
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
