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

Q:What is the relationship between the cushion and the ring beam?: Cushion is plain concrete or asphalt concrete (for groundwater soil corrosive strong site). Is located below the ground, in order to prevent the foundation or the concrete beam pouring when the excessive loss of water caused by defects set. The purpose is to ensure the quality of concrete, increase the durability of underground components

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:How to build a fine stone concrete cushion?: The main role of the cushion is to meet the requirements of the design elevation. In addition, the cushion to meet the sound insulation, insulation, insulation, slope and buried pipeline and other functional requirements and set a variety of levels.

Q:Basement floor mattress dry to what degree can do coil 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: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: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:Why do the basics of the cushion waterproofing: 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: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.
