- 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:Maintenance time of the cushion on the roof of the building
- for the incorporation of retarding admixture or impermeable concrete , Not less than 14d;
- Q:What is the difference between leveling and cushion?
- Cushion, the base material is not divided into materials at the same time, the design will be described. Material is the same concrete, the greater than 20CM calculated basis, less than, equal to 20CM calculated cushion. Leveling layer refers to the original structure due to the existence of uneven or slope and the laying of the base layer, is conducive to laying the surface layer or waterproof, insulation layer. The role is to play a leveling, looking for a slope or enhanced function.
- 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?
- Base cushion waterproofing is not contact with the soil (Ying water) to prevent water into the cushion, but in the cushion and the base of the bottom of the contact, in fact, is the basis of the bottom of the waterproof. The general basis of the foundation, the bar base is not necessary to do, like a raft in the basement, it is necessary to prevent the water from dipping into the basement (so the basement design may have to do anti-floating calculations).
- 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: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:Is foam concrete suitable for use as a cushion?
- The foamed concrete is a foaming system through a foaming machine that allows the foaming agent to be fully mechanically foamed and the foam is mixed evenly with the slurry.
- 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: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.
