- 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:Maintenance time of the cushion on the roof of the building
- Concrete watering maintenance time: the use of Portland cement, ordinary Portland cement or slag Portland cement mixed with concrete, not less than 7d;
- Q:How to build a fine stone concrete cushion?
- The cushion is primarily responsible for the load coming from the surface and passes the load evenly to the structural or base.
- 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: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:Can the cushion on the prefabricated board floor be dug?
- 1, can not be dug, the prefabricated board seam is too big.
2, in addition, now rarely used prefabricated panels, the earthquake effect is not good; especially after the Wenchuan earthquake. If it is cast-in-place floor, you can dig out.
- Q:Large area ground concrete cushion seam Why is the separation of joints generally concrete
- Second, sub-grid seam set
In order to reduce the total shrinkage and temperature stress of the large area waterproof layer, avoid the leakage of the waterproof layer due to the deformation of the structural layer and the change of the temperature and humidity, the waterproof layer should be divided according to the shape, size and structure of the flat roof, Stay sewn. The waterproof layer is divided into several squares.
- 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:Basement cushion 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:The top floor made waterproof playing cushion layer of how to do
- Roof leaking of the construction program:
1. Need to remove the previous waterproof, such as paint, coil, etc., if it is to do the mortar waterproof can not be eradicated.
