- 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:Why calculate the amount of time to count a lot of cushion ah
- In the building construction refers to the base is located below the cushion sometimes also served as grassroots. With the cushion, in the above work is convenient, clean, especially the mold, bar reinforced, pouring concrete and other processes, will not be affected by the basic earth pollution. Set the place where the cushion is generally based, floor, roof (slope) and so on.
- Q:Roof waterproof mattress should play the number of centimeters appropriate
- 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.
- Q:Do you need a cushion for roof waterproofing?
- If the base layer of the waterproof layer is flat or in line with the requirements of the waterproof material process, you can not do leveling layer. For example, in the cast-in-place concrete roof with the pound with wiping light, may serve as the waterproof layer of the grassroots.
- Q:The top floor made waterproof playing cushion layer of how to do
- 2. repair the cracks well. After the cracks to be repaired are dry, start waterproofing.
- 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: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: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.
- Q:Is the raft cushion waterproofing full of the cushion?
- The request is full.
Raft foundation do not do waterproof mainly depends on the design of the groundwater level considerations, calculated if the floor itself to meet the requirements, you can not do, and not rigid to do.
- Q:Do you need a cushion on the ground floor?
- First to ask the use of your huts, there is the strength of the huts.
If you just get a little, then a few years into a dangerous floor, then calculate the ground, walls, roof (slope roof) area, doors and windows can be used as a wood plate loss.
