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 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:Foam concrete for the roof cushion generally do much bulk ah

in recent years, the density of 160kg / m3 ultra-light foam concrete is also used in construction projects.

Q:What is the difference between leveling and cushion?

Cushion, the base material is not divided into materials at the same time, the design will be described. Material is the same concrete, the greater than 20CM calculated basis, less than, equal to 20CM calculated cushion. Leveling layer refers to the original structure due to the existence of uneven or slope and the laying of the base layer, is conducive to laying the surface layer or waterproof, insulation layer. The role is to play a leveling, looking for a slope or enhanced function.

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.

Q:Large area ground concrete cushion seam Why is the separation of joints generally concrete

First, the rigid waterproof layer in a large area of ??construction, by the external force, temperature, humidity changes, structural layer deformation and other factors prone to cracking, leading to leakage, the design should consider the deformation of the waterproof layer to take the necessary Structural or structural measures to avoid and mitigate the cracking of the waterproofing layer to achieve the desired waterproofing effect.

Q:Roof waterproof mattress should play the number of centimeters appropriate

? 3. The first layer to do flexible waterproof, that is, roof-specific anti-aging waterproof coating.

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: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:Basement cushion waterproof

Fourth, improve the waterproof performance: 1, Aggregate graded concrete, is the use of different aggregates of the aggregate and improve the content of cement mortar in the concrete, so that the mortar is filled between the aggregate, thus blocking the aggregate is not dense between the seepage channel , Improve water resistance; 2, plus concrete, is added in the concrete air conditioner or dense agent to improve the impermeability.
