Q: The cushion is usually in the housing which parts: First of all, the foundation refers to the basis of the ground below, the cushion is generally below the base, the base should be there, if the sewage treatment station, then you look at the sewage pool, the bottom of the pool should also have it

Q: Why do the basics of the cushion waterproofing: 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: 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: Basement cushion 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: 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: What is the relationship between the cushion and the ring beam?: There is no direct relationship between the cushion and the ring beam.

Q: Is foam concrete suitable for use as a cushion?: Inappropriate. Bubble concrete is a new type of energy-saving and environmentally friendly building materials, which are widely used in wall materials, but there are still some defects, such as low strength, cracking, water absorption, as the cushion of its strength is not enough standard.

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: Why calculate the amount of time to count a lot of cushion ah: Cushion cushion, as the name suggests is the structure of the liner layer, mainly from the back cover of the role, generally in the engineering design drawings have a clear approach (material).

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;
