Q: Can the cushion on the prefabricated board floor be dug?: Prefabricated board floor layer of cement layer is not called the cushion, should be called leveling layer, this layer can be removed, but be careful not to damage the prefabricated plate.

Q: The cushion is usually in the housing which parts: There was no other place in the house below

Q: When the cushion is used, the thickness of the protective layer is not less than (): The purpose of the protection, one is to avoid man-made mechanical damage; the second is to prevent climate, UV aging, to extend the service life; three in the planting roof protection layer is to prevent plant roots puncture, different effects using different methods of protection.

Q: The top floor made waterproof playing cushion layer of how to do: 3. The first layer to do a flexible waterproof, try the valve Bai fat together with the full bricks that are roof-specific anti-aging waterproof coating.

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: Can the floor tiles be removed from the cement mats on the prefabricated board floor?: Prefabricated board floor layer of cement layer is not called the cushion, should be called leveling layer, this layer can be eradicated, but should pay attention not to damage.

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: 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: Why calculate the amount of time to count a lot of cushion ah: It can be seen, in the preparation of the project budget, the cushion is also a very important sub-head, the amount of its calculation is often measured by m3, the current commonly used materials are concrete, gravel, stone, Stone slag), slag, slag concrete, lime and so on.

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;
