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: Large area ground concrete cushion seam Why is the separation of joints generally concrete: Large area of ??concrete after concrete construction, the concrete volume will be slightly inflated, the ground for a long time deposition, will be sinking, all large area of ??concrete construction, the general set of separation joints.

Q: What is the waterproof layer and the waterproof cushion in the tile roof?: Waterproof: In order to prevent rainwater from entering the roof, groundwater infiltrates the wall, the basement and the underground structures, and the indoor water penetrates the floor and the wall.

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: In the building construction refers to the base is located below the cushion sometimes also served as grassroots. With the cushion, in the above work is convenient, clean, especially the mold, bar reinforced, pouring concrete and other processes, will not be affected by the basic earth pollution. Set the place where the cushion is generally based, floor, roof (slope) and so on.

Q: Maintenance time of the cushion on the roof of the building: for the incorporation of retarding admixture or impermeable concrete , Not less than 14d;
