- 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: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:Basement floor mattress dry to what degree can do coil 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:What is the difference between leveling and cushion?
- Commonly used materials are, cement mortar leveling layer, fine stone concrete leveling layer, asphalt mortar leveling layer and so on. Leveling layer and the difference between the cushion, which is a very easy to confuse the two engineering concepts.
- 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: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:Is it possible to make a waterproof layer
- 1, to do after the dry do, or prone to the phenomenon of wall skin off.
- 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:Large area ground concrete cushion seam Why is the separation of joints generally concrete
- hird, the relevant parts
Different types of rigid waterproof layer separation spacing in addition to meet the calculation needs, but also in the following parts set sub-grid joints.
1. The deformation of the roof structure sensitive parts;
2. Roof and roof drainage direction changes;
3. The junction of the waterproofing layer and the protruding roof structure;
4. Under normal circumstances, each bay load-bearing walls should be set sub-grid seam.
5. Between the waterproof layer and the load-bearing or non-load-bearing parapet or gable should be set sub-grid joints, and in the node structure for proper treatment.
- Q:The cushion is usually in the housing which parts
- There was no other place in the house below
