Q:What is the waterproof layer and the waterproof cushion in the tile roof?
In the tile roof, to wait for the waterproof layer after the dry layer, or prone to the phenomenon of wall off. Waterproof layer set and standard construction methods: to be painted 2 to 3 times, or should be added fiberglass cloth, and each brushing the thickness of the cured material shall not be less than 1 mm, and should be completely dry (about 5-8 Hour) and then the next construction. After brushing, but also in the paint waterproof layer to do a mortar protective layer, and finally paste the tile.
Q:Is the raft cushion waterproofing full of the cushion?
As for the bottom of the bar thickness of the protective layer is generally 4cm, but if the basic floor of the concrete label is relatively high, the protective layer can be appropriately reduced.
Q:Can the floor tiles be removed from the cement mats on the prefabricated board floor?
Cushion generally no steel mesh, even if there can be removed, it is used to inhibit the cushion cement mortar layer cracking.
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 it possible to make a waterproof layer
3, waterproof layer set and standard construction methods: to be painted 2 to 3 times, or should be added fiberglass cloth, and each brushing the thickness of the cured material shall not be less than 1 mm, and should be completely dry (about 5 -8 hours) and then the next construction. After brushing, but also in the paint waterproof layer to do a mortar protective layer, and finally paste the tile.
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: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: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 do the basics of the cushion waterproofing
Base cushion waterproofing is not contact with the soil (Ying water) to prevent water into the cushion, but in the cushion and the base of the bottom of the contact, in fact, is the basis of the bottom of the waterproof.
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.
