- 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:Basement floor mattress dry to what degree can do coil waterproof?
- First, the basement moisture treatment structure is usually: first in the basement wall outer surface wiping 20mm thick 1: 2 waterproof mortar, basement walls should be used cement mortar masonry, gray seam must be full; and in the basement floor and the first Floor floor is divided into two walls of the level of moisture-proof layer. The outer wall of the basement wall should be tampered with the soil with poor permeability.
- Q:Foam concrete for the roof cushion generally do much bulk ah
- Foam concrete density grade is generally 300-1800kg / m3, commonly used foam concrete density grade 300-1200 kg / m3,
- Q:Do you need a cushion for roof waterproofing?
- There is no "cushion" on the roof, and there is a concrete cushion under the basement floor. What you said may be leveling, is the base of the waterproof layer.
- 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:Maintenance time of the cushion on the roof of the building
- According to the "concrete structure construction quality acceptance criteria" provides:
Concrete should be poured within 12h after the completion of the concrete to be covered, and moisturizing conservation;
- 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: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:Why do the basics of the cushion waterproofing
- 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.
- Q:Cushion, waterproof layer construction to do what information
- 2, bedding (bed course) refers to the structure below the grass-roots level. Its main role is to water, drainage, antifreeze to improve the grass-roots and soil-based working conditions, the water stability requirements are better. The cushion layer is a structural layer between the base layer and the soil base. When the soil quality is poor, it is used to improve the water stability of the soil base, improve the water stability and frost resistance of the pavement structure and disperse Load to reduce soil deformation.
