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: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:Foam concrete for the roof cushion generally do much bulk ah
First help you correct it, foam concrete used in the roof should be the role of thermal insulation, not as a cushion.
Q:Do you need a cushion for roof waterproofing?
Where the process (such as waterproof material construction, floor construction, equipment installation, etc.) on the grass-roots level have certain requirements, must be grass-roots leveling treatment, in the project, commonly used leveling method is to use a certain strength of cement mortar or Fine stone concrete leveling.
Q:Do you need a cushion on the ground floor?
Chalet recommended to do sloping roof, the lowest point suggested 2.4. Talk about the ground, the roof, the wall area divided by the length of your board length and width of the area can be calculated on the amount of it!
Q:Can the floor tiles be removed from the cement mats on the prefabricated board floor?
Prefabricated board floor layer of cement layer is not called the cushion, should be called leveling layer, this layer can be eradicated, but should pay attention not to damage.
Q:Basement cushion waterproof
Second, when the design of the highest groundwater level above the bottom of the basement floor, you must do waterproofing. As the waterproof waterproof effect is good, so the application of more. Internal waterproofing is generally used for repair works.
Q:How to build a fine stone concrete cushion?
Reduce ground cracking, plus steel mesh. Reinforced mesh, should be placed in the middle of the concrete, because the protective layer of concrete thick Fang generally only 5CM thickness, so the middle is the best.
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.
