Q:Basement cushion waterproof
Five, how the basement moisture: 1, moisture-proof material This is the decoration in the attention of the problem, the basement is relatively humid place, so when we should pay attention to the decoration, the choice of wallpaper, tiles and other moisture-proof effect of better decoration materials, and other basement ceiling, floor, walls are To be the best waterproof. 2, ventilation and moisture Strengthen the air circulation on the moisture is more helpful, can effectively reduce the indoor moisture content. 3, electrical dehumidification If you run into the rainy weather, outdoor air humidity is relatively high, it is not suitable for long ventilation, you can use the exhaust fan, air conditioning or dehumidifier and other machines for indoor dehumidification. 4, desiccant dehumidification In addition to the use of a variety of electrical dehumidification can also be placed some moisture damp dehumidification effect of small items, such as desiccant, charcoal and other indoor moisture, but the desiccant is a service life, the general need for frequent replacement. 5, to warm moisture Installation of warmth is also one of the effective means of underground moisture protection, to warm the basement room temperature can be maintained at a certain temperature can keep the room dry and not wet, but pay attention to the temperature is not too high will cause the room is too dry, Comfortable.
Q:Why calculate the amount of time to count a lot of cushion ah
Cushion cushion, as the name suggests is the structure of the liner layer, mainly from the back cover of the role, generally in the engineering design drawings have a clear approach (material).
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
  2. repair the cracks well. After the cracks to be repaired are dry, start waterproofing.
Q:The roof cushion is waterproof on the slope roof
When the moisture generated by the ice dam into the external walls of the gap, the walls and insulation layer will become damp, which is the ideal environment for the breeding of mold.
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:Do you need a cushion for roof waterproofing?
If the base layer of the waterproof layer is flat or in line with the requirements of the waterproof material process, you can not do leveling layer. For example, in the cast-in-place concrete roof with the pound with wiping light, may serve as the waterproof layer of the grassroots.
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:Cushion, waterproof layer construction to do what information
3, waterproof layer: In order to prevent the rain into the roof, groundwater into the wall, basement and underground structures, indoor water into the floor and walls and other materials layer.
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.
